Alternatively, both the first display mode and the second display mode may be shape display, where the shape of the first display mode is more prominent than the shape of the second display mode, for example, the shape of the first display mode is an arrow, and the second display mode is a circle.

Alternatively, the first distance may be user-set or preconfigured or acquired in real-time by the electronic device.

Alternatively, the first distance may be set by a user, who may set the first distance empirically.

Alternatively, in the case where the electronic device acquires the first distance in real time, the first distance may be one distance of a plurality of distances, and the electronic device may determine the first distance among the plurality of distances according to the current speed of the electronic device, for example, if the current speed of the electronic device is relatively fast, determine a relatively large first distance among the plurality of distances, and if the current speed of the electronic device is relatively slow, determine a relatively small first distance among the plurality of distances.

Alternatively, in the case where the electronic device acquires the first distance in real time, the first distance may be a product of a first preset time and a current speed of the electronic device, where the first preset time may be understood as a set time for reminding the user of the impending arrival at the first intersection in advance, the first preset time may be obtained empirically, that is, when a current first position of the electronic device is located at a distance from the first intersection that is smaller than a first distance obtained by the product of the first preset time and the current speed of the electronic device, the first navigation interface is displayed, and it should be understood that, on the premise that the first preset time is fixed, the higher the current speed of the electronic device, the larger the first distance, that is, the first navigation interface may be displayed at a position farther from the first intersection, the lower the current speed of the electronic device, and the smaller the first distance, that is, the first navigation interface may be displayed at a position closer to the first intersection.

In some possible implementations, the N branches are on the same side of the moving direction of the electronic device, and the total number of branches included in the first way is M; wherein M is a positive integer greater than or equal to N.

In the above scheme, the N branches of the first intersection are on the same side of the moving direction of the electronic device, that is, the N indication icons included in the first navigation interface include the indication icon of the target branch and the indication icon of the branch on the same side of the moving direction of the electronic device as the target branch, the M-N branches of the M branches except for the N branches are not on the same side as the target branch, so that the user can clearly distinguish the M-N branches, that is, the first navigation interface can display the indication icons of the branches which are easy to be confused by the user, and thus, the first navigation interface can be presented to the user clearly and simply, and too many indication icons are prevented from being displayed.

Alternatively, the direction of movement of the electronic device may be the direction of movement of the electronic device on the current road.

Alternatively, the same side of the movement direction of the electronic device may be the same side of the movement direction of the electronic device on the current road, that is, the N branches are all on the same side of the movement direction of the electronic device on the current road.

Optionally, if the direction of the target switch is the moving direction of the electronic device on the current road, that is, the direction of the target switch is the same as the moving direction of the electronic device on the current road, the N switches at the first intersection may include the target switch and switches adjacent to the target switch from left to right, that is, the N switches may not be limited to be on the same side of the moving direction of the electronic device at this time.

In the above solution, the gradient of the first switch of the N switches is a first angle, which may be understood as that the first switch is an uphill switch or a downhill switch, where the angle corresponding to the gradient of the uphill switch or the downhill switch is the first angle, and in order to better indicate the road condition of the first switch, the angle of the indication icon of the first switch relative to the road direction of the first intersection is the first angle, that is, the angle of the indication icon of each switch of the N switches relative to the road direction of the first intersection may indicate the gradient of the corresponding switch, for example, if the target switch is a road with a gradient, and the gradient of the target switch is the first angle, the angle of the indication icon corresponding to the target switch relative to the road direction of the first intersection is the first angle. Therefore, the gradient of the turnout can be expressed by indicating the pitch angle of the icon and the actual road surface direction in the road with gradient, and the user can know the road condition of each turnout in N turnouts of the first intersection in more detail according to the first navigation interface, so that the user can conveniently drive towards the target turnout.

In the above scheme, when the electronic device moves from the first position smaller than the first distance to the second position smaller than the second distance, the electronic device is shown to be continuously close to the first intersection, the user can more clearly see the first intersection, differences between adjacent intersections are larger than the second preset angle and smaller than the first preset angle are gradually obvious, then the indication icons of N-P obvious in differences can disappear, at the moment, the first navigation interface can be switched to the second navigation interface, in this way, the second navigation interface is clearer and simpler than the first navigation interface, the indication mode of the indication icons of the target switches in the P switch ways is the same as the indication mode of the target switches in the N switch ways in the first navigation interface, the indication mode of the indication icons of the switch ways except the target switches in the P switch ways is the same as the indication mode of the indication icons of the switch ways except the target switches in the first navigation interface, that the indication mode of the indication icons of the target switches in the P switch ways included in the second navigation interface is the same as the indication mode of the indication icons of the switch ways except the target switches in the N switch ways, and thus the target switches in the P switch ways can be distinguished from the second navigation interface according to the indication mode.

Alternatively, the third branch may be any one of the P branches. Alternatively, the third angle may be a vector including a magnitude and a direction, the third angle may be a positive number, which may indicate that the third branch is an uphill branch, or a negative number, which may indicate that the third branch is a downhill branch.

Optionally, any adjacent turnout angle in the P turnouts is smaller than or equal to a second preset angle.

Alternatively, the second distance may be user-set or preconfigured or acquired in real-time by the electronic device.

Alternatively, in the case where the electronic device acquires the second distance in real time, the second distance may be one distance of a plurality of distances, and the electronic device may determine the second distance among the plurality of distances according to the current speed of the electronic device, for example, if the current speed of the electronic device is relatively fast, determine a relatively large second distance among the plurality of distances, and if the current speed of the electronic device is relatively slow, determine a relatively small second distance among the plurality of distances.

Optionally, in the case that the electronic device acquires the second distance in real time, the second distance may be a product of a second preset time and a current speed of the electronic device, where the second preset time may be understood as a time when the set difference is obvious and the branch road disappears, the second preset time may be obtained empirically, that is, when the distance between the current second position of the electronic device and the first intersection is smaller than the second distance obtained by the product of the second preset time and the current speed of the electronic device, the second navigation interface is displayed, and it should be understood that, on the premise that the second preset time is fixed, the higher the current speed of the electronic device, the larger the second distance, that is, the second navigation interface may be displayed at a position farther from the first intersection, the lower the current speed of the electronic device, and the smaller the second distance, that is, the second navigation interface may be displayed at a position closer to the first intersection.

Alternatively, the second preset angle may be user-set or preconfigured, and the second preset angle may be an empirically derived angle value.

Alternatively, the P branches may be part or all of the N branches.

In some possible implementation manners, the arrangement manner of the N indication icons of the N branches of the first intersection in the first navigation interface is a first arrangement manner, if the indication icon of the second branch of the N branches of the first intersection is at the boundary of the display area of the electronic device, a third navigation interface is displayed, the arrangement manner of the N indication icons of the N branches of the first intersection in the third navigation interface is a second arrangement manner, and in the second arrangement manner, any one indication icon of the N indication icons of the N branches is in the display area of the electronic device; wherein the first arrangement is different from the second arrangement.

In the above scheme, when the electronic device is closer to the first intersection, the range of the road that can be covered by the display area of the electronic device is gradually smaller, and the second branch of the N branches of the first intersection may appear at the boundary of the display area of the electronic device, at this time, the arrangement mode of the N indication icons of the N branches in the first navigation interface needs to be changed, and the first navigation interface may be switched to the third navigation interface, so that the N indication icons of the N branches in the third navigation interface are all in the display area of the electronic device. The arrangement mode of N indication icons of N turnouts of the first intersection in the third navigation interface is a second arrangement mode, which is different from the first arrangement mode of N indication icons of N turnouts of the first intersection in the first navigation interface, under the second arrangement mode, any indication icon of N indication icons of N turnouts is in a display area of the electronic equipment, wherein the first arrangement mode is different from the second arrangement mode. Therefore, the indication icons of the turnout which are out of the coverage range of the display area of the electronic equipment can still display the relative position relation between the indication icons and the adjacent turnout in the third navigation interface, so that a user is helped to distinguish the target turnout and accurately grasp the time for turning to the target turnout.

Optionally, when the electronic device includes an ARHUD device, the display area of the ARHUD device is an AR area of the ARHUD, and the AR area is configured to display a third navigation interface, if the indication icons of the second branch in the N branches at the first intersection are at the boundary of the AR area, at this time, the arrangement manner of the N indication icons of the N branches in the first navigation interface is changed, and the first navigation interface may be switched to the third navigation interface, so that the N indication icons of the N branches in the third navigation interface are all in the AR area. In this way, the N indication icons of the N branches in the third navigation interface may not be completely and accurately attached to the actual N branches, but the user may still identify the target branch through the relative positional relationship of the N indication icons of the N branches in the third navigation interface.

Optionally, the arrangement manner of the P indication icons may be the positions of the P indication icons in the display area of the electronic device, in the third arrangement manner and the fourth arrangement manner, the relative positional relationship of the P indication icons is unchanged, for example, the second arrangement manner of the P indication icons of the P branches of the first intersection in the second navigation interface is a lateral distribution, the fourth arrangement manner of the P indication icons of the P branches of the first intersection in the ninth navigation interface may be a longitudinal distribution, and in the lateral distribution and the longitudinal distribution, for example, the relative positional relationship of the indication icons 1 and the indication icons 2 is unchanged, for example, in the lateral distribution, the indication icons 1 are on the left of the indication icons 2, and in the longitudinal distribution, the indication icons 1 are also on the left of the indication icons 2.

Alternatively, the first arrangement and the third arrangement may be the same or different, and the second arrangement and the fourth arrangement may be the same or different.

That is, the tenth navigation interface may be different from the second navigation interface in display manner of the indication icon of the target branch, and the display manner of the indication icon of the target branch may be changed from the first display manner to the third display manner, so that the user may be reminded of turning to the target branch again in time by changing the display manner of the indication icon of the target branch in the tenth navigation interface.

In some possible implementations, the indication icon of each turnout is an indication arrow, and the direction indicated by the indication arrow of each turnout is a turnout direction of each turnout.

In the above scheme, the indication icon of each of the N branches at the first intersection is an indication arrow, and the direction indicated by the indication arrow of each branch is the branch direction of the corresponding branch, so that the indication icon in the navigation interface can not only distinguish the target branch from branches other than the target branch, but also indicate the direction of each branch, thereby better helping the user to distinguish the direction of the target branch to be turned.

Alternatively, the indication icon of each turnout may be an indication icon of any shape, and the indication icons of turnout other than the target turnout among the N turnouts have the same shape.

For easy understanding, the following embodiments of the present application will take an electronic device having a structure shown in fig. 1 and fig. 2 as an example, and specifically describe a method for navigation provided in the embodiments of the present application with reference to the accompanying drawings and application scenarios.

In car navigation, because the road is complex and diverse in form, for the road of complex form, more accurate navigation instructions are required to guide the user to drive the vehicle to the destination. For example, when a user needs to pass through the intersections of a plurality of turnouts when the user drives the vehicle and the distances between the target turnouts of the plurality of turnouts and the turnouts other than the target turnouts are relatively close, a navigation method is needed to help the user clearly distinguish the target turnouts and turnouts adjacent to the target turnouts, so as to effectively help the user to grasp the time for steering the target turnouts, thereby avoiding the user from driving the vehicle to walk wrong turnouts or missing the target turnouts.

The ARHUD and an application scenario of the ARHUD in vehicle navigation according to the embodiments of the present application will be described first.

The ARHUD may be understood as a combination of AR technology and head-up display (HUD) technology, in which the HUD may project vehicle running information or navigation information directly in front of a driver's line of sight, so that the driver may not need to frequently look down at the vehicle running information or navigation information displayed in an instrument panel or an on-board center control screen of the vehicle, thereby improving driving safety and convenience. The AR technology can fuse virtual information with a real scene, the ARHUD can integrate navigation information to a front road through vehicle navigation information and real road condition information, that is, the ARHUD can fuse the displayed navigation information with an actual road seen by a driver, and more visual navigation experience can be provided for the driver.

Fig. 3 is a schematic view of a scene based on ARHUD navigation, in which the indication icon displayed in the AR area in fig. 3 may be superimposed into a real scene, and in combination with an actual road surface, a user may clearly recognize the condition of a road ahead through the indication icon displayed right ahead. The virtual image plane in fig. 3 may present a navigation interface, where the navigation interface includes an indication icon, and the virtual image plane may also present vehicle driving information, which is not limited in this application, for example, the vehicle driving information may include a vehicle speed, a duration, or a tire pressure, and the virtual image plane in fig. 3 may be an AR frame. The virtual image distance (virtual image distance, VID) in FIG. 3 may be the distance between the focal point of the virtual image and the eyes of the user, and theoretically, the longer the VID can cover, the larger the size of the virtual image plane, the better the ARHUD effect, e.g., the VID of the ARHUD can be 10 m-13 m. The field of view (FOV) in fig. 3 includes a horizontal FOV and a vertical FOV, the horizontal FOV is an angle formed by two edges of the maximum range in the horizontal direction in which the eyes see the virtual image, the vertical FOV is an angle formed by one eye as a vertex and two edges of the maximum range in the vertical direction in which the eyes see the virtual image, the FOV can reflect the size of the virtual image plane that the user can see, i.e., the size of the AR frame, for example, the horizontal FOV can reach 10 ° or more, the vertical FOV can reach 4 ° or more, theoretically, the larger the FOV, the larger the size of the virtual image plane, i.e., the AR frame, the larger the AR frame, the real road can be covered by the larger AR frame, the AR region is a region formed by four dotted lines of the vertex and four vertices of the virtual image plane, and the region of the virtual image plane, which is far from the direction of the eyes, the AR region is used for displaying the navigation interface, that is, the navigation interface displayed in the AR region can be said as the navigation interface. In the case of guaranteeing the VID, if the FOV is to be enlarged to achieve that the AR area can cover a wider range of real roads, there is a high technical requirement on the optical design, for example, when the VID is 10m, the horizontal angle of view in the FOV is about 10 °, the AR area of the ARHUD can cover a real road of about one half lane at a distance of 20m from the current position of the vehicle, and cover a real road of about three lanes at a distance of 50m from the current position of the vehicle.

The following specifically describes a scenario possibly related to the present application, and describes a technical solution in an embodiment of the present application in detail in combination with the scenario.

Fig. 4 (a) is a schematic view of a scenario of a plurality of intersections of a turnout provided in this embodiment of the present application, when a user drives a vehicle to drive into an intersection of a plurality of turnouts, if an included angle between adjacent turnouts of the plurality of turnouts is smaller, it is difficult for the user to clearly and intuitively distinguish a target turnout in a thumbnail of a navigation map according to an indication icon marked in the thumbnail, as in a navigation interface shown in fig. 4 (b), at this time, the user needs to carefully check the target turnout indicated by the indication icon in the thumbnail in the navigation interface, and the line of sight of the user can be switched back and forth between the thumbnail of the navigation map and an actual intersection, so that the attention of the user for driving the vehicle is easily dispersed, causing a certain potential safety hazard, and the user may also be referred to as a driver. In some embodiments, in order to better solve the problem of potential safety hazards caused by the fact that the line of sight of the user switches back and forth between the thumbnail of the navigation map and the actual intersection, navigation may be performed based on the ARHUD, in the ARHUD, the indication icon may be superimposed into the actual intersection, although the user may not need to view the indication icon marked in the thumbnail of the navigation map, but the included angle between the target switch and the adjacent switch in the plurality of switch ways is smaller, that is, the target switch and the adjacent switch way are closer, so that the adjacent switch ways with smaller included angles cannot be well distinguished by the indication icon, as shown in (c) of fig. 4, based on the schematic view of ARHUD navigation in the intersection scene of the plurality of switch ways, the indication icon in the navigation interface displayed in front of the line of sight of the user may be combined with the actual road surface, and because the included angle between the target switch way and the adjacent switch way in the actual intersection is smaller, the direction of the target switch way indicated by the indication icon displayed by the user according to the AR area cannot distinguish the target switch way from the target switch way to the target switch way, and the target switch way, or the target switch way can not be accurately turned to the target switch way, or the target switch way can not be missed.

In this regard, the embodiment of the application provides a method for navigation, so as to improve the navigation accuracy under the navigation of the intersections of a plurality of turnouts, help the user to drive the vehicle to accurately grasp the turning time, and avoid to go wrong turnouts or miss target turnouts.

Alternatively, the electronic device may determine N branches of the first intersection according to the map information, and in the case where the N branches are all branches of the first intersection, as in fig. 6 (a) or (b), the 4 branches of the first intersection may be determined by the electronic device according to the map information.

Optionally, in the case that the N branches are part of the branches of the first intersection, the determining, by the electronic device, the N branches of the first intersection according to the map information may include: and the electronic equipment determines N branches of the first intersection according to the map information and all branches of the first intersection. As in fig. 7, the 3 branches of the first intersection in fig. 7 (a) or (b) may be that the electronic device determines 4 branches of the first intersection according to the map information, and then determines 3 branches of the first intersection in fig. 7 (a) or (b) according to the map information and the 4 branches of the first intersection.

The first navigation interface in fig. 7 (a) or (b) includes 3 indication icons of 3 branches of the first intersection, one indication icon indicating one of the 3 branches.

Alternatively, the first display mode is more conspicuous than the second display mode, and can be understood as: the first display mode is more prominent than the second display mode, or the first display mode is more noticeable to the user than the second display mode. Alternatively, both the first display mode and the second display mode may be brightness display, where the brightness of the first display mode is higher than the brightness of the second display mode, for example, the first display mode is highlighting display, and the second display mode is gray scale display. Optionally, the first display mode and the second display mode are both color display, the color of the first display mode is more prominent than the color of the second display mode, for example, the color of the first display mode is green, and the color of the second display mode is gray; alternatively, traffic corresponding to the color of the first display mode is indicated as traffic, traffic corresponding to the color of the second display mode is indicated as no traffic, for example, the color of the first display mode is green, and the color of the second display mode is red. Alternatively, both the first display mode and the second display mode may be shape display, where the shape of the first display mode is more prominent than the shape of the second display mode, for example, the shape of the first display mode is an arrow, and the second display mode is a circle. The indication icons of the branches except the target branches are displayed in the same mode, so that a user can clearly distinguish the target branches from the branches except the target branches. As shown in fig. 6 (a) or (b), or as shown in fig. 7 (a) or (b), the indication icon of the target switch in the first navigation interface is displayed in a more prominent manner than the indication icon of the switch other than the target switch.

For example, the first distance is 70m, and the first navigation interface is displayed when the current first position of the electronic device is less than 70m from the first intersection.

Alternatively, in the case where the electronic device acquires the first distance in real time, the first distance may be one distance of a plurality of distances, and the electronic device may determine the first distance among the plurality of distances according to a current speed of the electronic device, for example, if the current speed of the electronic device is relatively fast, determine a relatively large first distance among the plurality of distances, and if the current speed of the electronic device is relatively slow, determine a relatively small first distance among the plurality of distances, where a correspondence between the plurality of distances and the speed may be obtained empirically. For example, the plurality of distances are 60m and 70m, and when the current speed of the electronic device is greater than or equal to 40km/h, the first distance is determined to be 70m, and when the current speed of the electronic device is less than 40km/h, the first distance is determined to be 60m.

Alternatively, in the case where M is equal to N, all the branches of the first intersection are represented on the same side of the movement direction of the electronic device, and in the case where M is greater than N, part of the branches of the first intersection are represented on the same side of the movement direction of the electronic device.

As shown in fig. 7 (a) or (b), 3 branches at the first intersection included in the first navigation interface are a second branch from the left in fig. 7 (a) or (b), a third branch, and a fourth branch, where the 3 branches are all on the same side of the movement direction of the vehicle driven by the user, the total number of branches included in the actual first intersection is 4, and the first branch from the left in fig. 7 (a) or (b) is the other side of the movement direction of the electronic device.

When M is greater than N, as shown in fig. 8 (a) or (b), the total number of branches included in the first intersection is 4, because the direction of the target branch is the same as the moving direction of the vehicle driven by the user on the current road, N branches of the first intersection are 3 branches of the first intersection, that is, N is 3, the 3 branches of the first intersection include the target branch and the branches adjacent to the target branch from left to right, specifically, the first branch is from left of the first intersection in fig. 8 (a) or (b), the second branch and the third branch are the target branch, the first navigation interface in fig. 8 (a) or (b) includes 3 indication icons of the 3 branches, specifically, the first navigation interface shown in fig. 8 (a) may be the navigation interface presented by the indication icon displayed in the thumbnail of the navigation map, the navigation interface shown in fig. 8 (b) may be the navigation interface shown in fig. 8 (b) is the navigation scene displayed in the front of the vehicle in fig. 8 (d) or (d) of the user on the basis of the map, and the display device may be mounted in the front of the map 8 (d) of the vehicle in the actual driving area.

Optionally, the angle between any two adjacent branches in the N branches at the first intersection is smaller than a first preset angle, the total number of branches included in the first intersection is M, and M is a positive integer greater than or equal to N. That is, the N branches are easy to be confused in the user's line of sight, so that the first navigation interface may display N indication icons of the N branches that are confused by the user, in other words, if there are two adjacent branches in the M branches at the first intersection, the indication icon of one of the two branches having an angle between the adjacent branches greater than the first preset angle may not be included in the first navigation interface, and because the branches having an angle between the adjacent branches greater than the first preset angle may be clearly distinguished in the user's line of sight, the first navigation interface may not include the indication icon of the branch having a larger angle between the adjacent branches, so that the first navigation interface may be presented to the user clearly and simply, and display of too many indication icons is avoided. Optionally, under the condition that M is equal to N, an angle between any two adjacent branches in all branches representing the first intersection is smaller than a first preset angle; and when M is larger than N, the angle between any two adjacent branches in the partial branches representing the first intersection is smaller than a first preset angle.

In the case where M is greater than N, for example, the first preset angle is 45 °, as shown in (a) or (b) of fig. 9, the angle between the left first branch and the left second branch of the first intersection is 50 °, and the angle between the left second branch and the left third branch is 40 °, the angle between the left third branch and the left fourth branch is 30 °, that is, the angle between the left second branch, the left third branch and the left fourth branch of the first intersection is 30 °, that is, the angle between any two adjacent branches in these 3 branches is less than 45 °, the first navigation interface of (a) or (b) of fig. 9 includes an indication icon of each branch in these 3 branches, specifically, the first navigation interface shown in (a) of fig. 9 may be a navigation interface presented by an indication icon displayed in a thumbnail of the navigation map, that is, the (b) of fig. 9 is a navigation scene that may be displayed in a schematic view of fig. 9 in front of an actual vehicle, and the display of (a) of fig. 9 may be a user-to-vehicle in a map display area (d) of the user-in which the user-interface is a map is installed in front of the map (a) of the vehicle.

For example, 3 branches of the first intersection in fig. 9 (a) or (b) refer to a second branch from the left, a third branch from the left, and a fourth branch from the left, all of which are on the same side of the direction of movement of the vehicle driven by the user, and the first branch from the left is on the other side of the direction of movement of the vehicle driven by the user, so that the angle between any two adjacent 3 branches of the first intersection included in the first navigation interface in fig. 9 (a) or (b) is smaller than the first preset angle, and all of which are on the same side of the direction of movement of the electronic device.

Optionally, if the target switch is included in two switches of the M switches of the first intersection, where the angle between adjacent switches is greater than the first preset angle, the first navigation interface may not include an indication icon of a switch that is not the target switch in the adjacent switches. For example, the first preset angle is 45 °, in the graph (a) or the graph (b) of fig. 10, the angle between the left-hand first branch and the left-hand second branch is 50 °, the angle between the left-hand second branch and the left-hand third branch is 50 °, the angle between the left-hand third branch and the left-hand fourth branch is 30 °, and the left-hand third branch is the target branch, wherein the angle between the left-hand second branch and the target branch of the first intersection is greater than the first preset value, and the target branch is included in the two branches, then the first navigation interface in the graph (a) or the graph (b) of fig. 10 includes the indication icon of the target branch and the indication icon of the left-hand fourth branch of the first intersection, the indication icon of the second branch from the left is not included, specifically, the first navigation interface shown in (a) of fig. 10 may be a navigation interface presented by the indication icon displayed in the thumbnail of the navigation map, and (b) of fig. 10 is a scene diagram under ARHUD-based navigation, and (b) of fig. 10 may be presented in front of the user's line of sight by superimposing the first navigation interface displayed in the AR area over the actual intersection, wherein the electronic device may be the user-driven vehicle in (b) of fig. 10 or the ARHUD device installed in the user-driven vehicle in (b) of fig. 10.

Optionally, the gradient of the first switch of the N switches of the first intersection is a first angle, and the angle of the indication icon of the first switch of the first intersection included in the first navigation interface relative to the road surface direction of the first intersection is a first angle, where the first switch may be any switch of the N switches, and the first navigation interface and the first intersection belong to the same coordinate system, for example, all belong to a world coordinate system, that is, the angle of the indication icon of each switch of the N switches relative to the road surface direction of the first intersection may indicate the gradient of the corresponding switch. In this way, the gradient of the branch road can be represented by the angle between the indication icon and the actual road surface direction in the road with gradient, and the user can know the road condition of each of the N branch roads of the first intersection in more detail according to the first navigation interface.

Optionally, the electronic device may include an ARHUD device, where a display area of the ARHUD device is an AR area of the ARHUD, the AR area is configured to display a first navigation interface, a gradient of a first branch of the N branches is a first angle, and an angle of an indication icon of the first branch of the first intersection included in the first navigation interface relative to a road surface direction of the first intersection is the first angle, so that the indication icon of the first branch in the first navigation interface may be better attached to an actual road surface.

Alternatively, the first switch may be any one of the N switches, for example, the first switch may be the target switch or may not be the target switch. That is, if any one of the N branches forms an angle with the actual road surface direction of the first intersection, the indication icon of the branch that forms an angle with the actual road surface direction of the first intersection in the first navigation interface also forms an angle with the actual road surface direction of the first intersection.

Alternatively, the first angle may be a vector comprising a magnitude and a direction, the first angle may be a positive number, which may for example indicate that the first switch is an uphill switch, or a negative number, which may indicate that the first switch is a downhill switch.

For example, on the basis of the diagram (b) of fig. 9, there may be fig. 11, where fig. 11 is a schematic view showing a scene based on ARHUD navigation at an intersection of a plurality of branches, and the electronic device may be the vehicle driven by the user in fig. 11 or an ARHUD device installed in the vehicle driven by the user in fig. 11. The third switch from the left of the first intersection in fig. 11 is the target switch, and the target switch is the first switch, that is, the target switch is a road with a gradient, for example, the target switch is an uphill switch, and the gradient of the target switch is 15 °, so that the angle of the indication icon corresponding to the target switch with respect to the road surface direction of the first intersection is 15 °, and the angle of the indication icon of the third switch from the left of the first navigation interface displayed in the AR area in fig. 11 is 15 °, so that the indication icon of the target switch in fig. 11 can be better attached to the actual target switch.

The embodiment in which fig. 11 is also applicable to the scenario of fig. 6 (b), fig. 7 (b), fig. 8 (b), fig. 9 (b), or fig. 10 (b), that is, the gradient of the first branch road among the N branch roads of the first intersection is the first angle, and the angle of the indication icon of the first branch road of the first intersection included in the first navigation interface displayed in the AR area with respect to the road surface direction of the first intersection is the first angle may be applicable to any scenario, and it is not limited that the angle between any two adjacent branch roads among the N branch roads of the first intersection is smaller than the first preset angle, and that the N branch roads of the first intersection are located on the same side surface in the moving direction of the electronic device, where the first navigation interface displayed in the AR area and the first intersection belong to the same coordinate system.

Optionally, the arrangement mode of the N indication icons of the N branches of the first intersection in the first navigation interface is a first arrangement mode, if the indication icon of the second branch of the N branches of the first intersection is at the boundary of the display area of the electronic device, displaying a third navigation interface, wherein the arrangement mode of the N indication icons of the N branches of the first intersection in the third navigation interface is a second arrangement mode, and under the second arrangement mode, any one indication icon of the N indication icons of the N branches is in the display area of the electronic device; wherein the first arrangement is different from the second arrangement.

Optionally, when the electronic device includes an ARHUD device, the display area of the ARHUD device is an AR area of the ARHUD, where the AR area is used to display the third navigation interface, when the electronic device is closer to the first intersection, a range of a road that can be covered by the AR area is gradually smaller, and indication icons of the second branch in the N branches of the first intersection may appear on a boundary of the AR area, at this time, an arrangement manner of the N indication icons of the N branches in the first navigation interface needs to be changed, and the first navigation interface may be switched to the third navigation interface, so that the N indication icons of the N branches in the third navigation interface are all in the AR area. The arrangement mode of N indication icons of N turnouts of the first intersection in the third navigation interface is a second arrangement mode, which is different from the first arrangement mode of N indication icons of N turnouts of the first intersection in the first navigation interface, and any indication icon of N indication icons of N turnouts is in an AR area under the second arrangement mode, wherein the first arrangement mode is different from the second arrangement mode. Therefore, the indication icons of the turnout which are out of the coverage range of the AR area can still display the relative position relation with the adjacent turnout in the third navigation interface, so that a user is helped to distinguish the target turnout and accurately grasp the time for turning to the target turnout. For example, in the case where the arrangement of 3 indication icons of 3 branches in the first navigation interface displayed in the AR area in fig. 9 (b) is the first arrangement, as the electronic device moves, the range of the road that the AR area may cover becomes gradually smaller, the fourth branch from the left of the first intersection in fig. 9 (b) may appear outside the range covered by the AR area, when the indication icon of 3 branches in the third navigation interface displayed in the AR area from the left appears at the boundary of the AR area, the first navigation interface displayed in the AR area in fig. 9 (b) may become the third navigation interface in fig. 12, as shown in fig. 12 is a scene diagram based on ARHUD navigation under the intersections of a plurality of branches, the electronic device may be a vehicle driven by the user in fig. 12 or an ARHUD device installed in the vehicle driven by the user in fig. 12, the arrangement of 3 indication icons of 3 branches in the third navigation interface displayed in the AR area from the left may be the third navigation interface displayed in the AR area is the boundary of the AR area, the arrangement of 3 indication icons of 3 branches in the 3 d is different from the current arrangement of the first navigation interface in the first position in the AR area (h) in the current position in the first navigation interface in fig. 9 (h) of the distance between the user icons in fig. 3.

Alternatively, the second branch may be any one of the N branches.

Optionally, the arrangement manner of the N indication icons may arrange the positions of the N indication icons in the display area of the electronic device, in the first arrangement manner and the second arrangement manner, the relative positional relationship of the N indication icons is unchanged, for example, the first arrangement manner of the N indication icons of the N branches of the first intersection in the first navigation interface is a lateral distribution, and the second arrangement manner of the N indication icons of the N branches of the first intersection in the third navigation interface may be a longitudinal redistribution of the N indication icons that are laterally distributed, under the lateral distribution and the longitudinal distribution, for example, the relative positional relationship of the indication icons 1 and the indication icons 2 is unchanged, for example, under the lateral distribution, the indication icons 1 are on the left side of the indication icons 2, and under the longitudinal distribution, the indication icons 1 are also on the left side of the indication icons 2.

For example, the arrangement of 3 indication icons of 3 branches in the first navigation interface displayed in the AR area shown in fig. 9 (b) is a first arrangement in which the indication icon of the second branch from the left is on the left of the indication icon of the third branch from the left, and the arrangement of 3 indication icons of 3 branches in the third navigation interface displayed in the AR area shown in fig. 12 is a second arrangement in which the indication icon of the second branch from the left is on the upper left of the indication icon of the third branch from the left.

Optionally, when the electronic device moves to the first intersection, the user needs to be prompted to perform an operation of turning to the target intersection, and at this time, a fourth navigation interface is displayed, where the fourth navigation interface includes an indication icon of each of N branches of the first intersection, a display mode of the indication icon of the target intersection in the N branches is a third display mode, a display mode of the indication icons of the branches other than the target intersection in the N branches is a second display mode, and the third display mode is different from the first display mode, and the third display mode is more striking than the second display mode. That is, compared with the first navigation interface, the fourth navigation interface may be different in display mode of the indication icon of the target turnout, and the display mode of the indication icon of the target turnout may be changed from the first display mode to the third display mode, so that the user can be reminded of turning to the target turnout again by changing the display mode of the indication icon of the target turnout in the fourth navigation interface.

Optionally, the third display mode is more striking than the second display mode, which can be understood as: the third display mode is more prominent than the second display mode or the third display mode is more noticeable to the user than the second display mode. Optionally, the third display mode is different from the first display mode, and may be understood as: when the first display mode and the second display mode are both display modes indicating the same characteristic of the icon, the third display mode is a display mode indicating another characteristic of the icon, for example, the first display mode and the second display mode may be both brightness display, the third display mode may be color display, for example, the first display mode and the second display mode may be both brightness display, and the third display mode may be shape display; or the third display mode may be dynamic display of the indication icon, the first display mode and the second display mode are static display of the indication icon, for example, the third display mode is flashing display of the indication icon of the target turnout, the first display mode is static display of the indication icon of the target turnout, and the second display mode is static display of the indication icons of turnout except the target turnout in the N turnout. Optionally, the third display mode, different from the first display mode, may include: the third display mode is hollow display of the indication icon, the first display mode is solid display or the first display mode is hollow display, and the third display mode is solid display.

For example, in the first navigation interface shown in fig. 7 (a) or (b), the display mode of the indication icon of the target switch is the first display mode, the display mode of the indication icon of the switch other than the target switch is the second display mode, and as the electronic device moves, when the electronic device moves to the first intersection, the first navigation interface in fig. 7 (a) or (b) may become the fourth navigation interface in fig. 13 (a) or (b), the fourth navigation interface shown in fig. 13 (a) may be the navigation interface presented by the indication icon displayed in the thumbnail of the navigation map, the fig. 13 (b) is a scene diagram based on ARHUD navigation under the intersections of the plurality of switches, and the fourth navigation interface displayed in the AR area may be superimposed in front of the user's line of sight in the actual intersection, wherein the electronic device may be the vehicle driven by the user in fig. 13 (b) or the vehicle driven by the vehicle installed in the user's fig. 13 (b). The third display mode of the indication icon of the target branch in the fourth navigation interface in fig. 13 (a) is different from the display mode of the indication icon of the target branch in the first navigation interface shown in fig. 7 (a). Alternatively, the third display mode of the target-branch indication icon in the fourth navigation interface displayed in the AR area in the diagram (b) shown in fig. 13 is different from the display mode of the target-branch indication icon in the first navigation interface displayed in the AR area shown in the diagram (b) shown in fig. 7, and the display mode of the target-branch indication icon in the diagram (a) or the diagram (b) shown in fig. 13 is more conspicuous than the display mode of the target-branch indication icon other than the target-branch.

Optionally, when the electronic device continuously approaches the first intersection, the user can more clearly see the first intersection, the difference between the adjacent intersections with the angle larger than the second preset angle and smaller than the first preset angle is gradually obvious, then the indication icons of the N-P intersections with obvious differences can disappear, and the first navigation interface can be switched to the second navigation interface at this time, so that the second navigation interface is clearer and simpler than the first navigation interface, that is, when the distance between the current second position of the electronic device and the first intersection is smaller than the second distance, the second navigation interface is displayed, the second navigation interface comprises the indication icon of each intersection in the P intersections with the first intersection, the indication icon of the target intersection in the P intersections is displayed in a first display mode, the indication icons of the intersections except the target intersection in the P intersections are displayed in a second display mode, P is a positive integer smaller than or equal to N, and the distance between any one intersection in the N-P intersections and the adjacent intersection with the N intersections is larger than the first preset angle and smaller than the first distance.

Alternatively, the second distance may be set by a user, who may empirically set the second distance. For example, the second distance is 40m, and when the current second position of the electronic device is less than 40m from the first intersection, a second navigation interface is displayed.

Alternatively, in the case where the electronic device acquires the second distance in real time, the second distance may be one distance of a plurality of distances, and the electronic device may determine the second distance among the plurality of distances according to the current speed of the electronic device, for example, if the current speed of the electronic device is relatively fast, determine a relatively large second distance among the plurality of distances, and if the current speed of the electronic device is relatively slow, determine a relatively small second distance among the plurality of distances. The correspondence between the plurality of second distances and the speed may be obtained empirically, for example, the plurality of second distances is 30m and 40m, when the current speed of the electronic device is greater than or equal to 40km/h, the second distance is determined to be 40m, and when the current speed of the electronic device is less than 40km/h, the second distance is determined to be 30m.

Optionally, in the case that the electronic device acquires the second distance in real time, the second distance may be a product of a second preset time and a current speed of the electronic device, where the second preset time may be understood as a time when the set difference is obvious and the branch road disappears, the second preset time may be obtained empirically, that is, when the distance between the current second position of the electronic device and the first intersection is smaller than the second distance obtained by the product of the second preset time and the current speed of the electronic device, the second navigation interface is displayed, and it should be understood that, on the premise that the second preset time is fixed, the higher the current speed of the electronic device, the larger the second distance, that is, the second navigation interface may be displayed at a position farther from the first intersection, the lower the current speed of the electronic device, and the smaller the second distance, that is, the second navigation interface may be displayed at a position closer to the first intersection. For example, the second preset time is 3 seconds, the current moving speed of the electronic device is 40km/h, and then when the distance between the electronic device and the first road is less than 33.33m, the second navigation interface is displayed. Optionally, the second preset time is less than the first preset time, and the second preset time may be S/T times the first preset time, where T is greater than S, and T and S are positive integers.

Optionally, the first preset angle is greater than the second preset angle.

Alternatively, the P branches may be part or all of the N branches.

Optionally, when the electronic device moves from the first position smaller than the first distance to the second position smaller than the second distance, if N-P intersections exist among N branches of the first intersection, where an angle between adjacent branches is greater than a second preset angle and smaller than the first preset angle, the second navigation interface includes an indication icon of each of P branches of the first intersection, and at this time, the P branches are part of the N branches.

For example, the second preset angle is 35 °, the first preset angle is 45 °, in the case of 3 indication icons of 3 branches in the first navigation interface in the (a) diagram or the (b) diagram of fig. 9, when the electronic device moves from the first position smaller than the first distance to the second position smaller than the second distance, the angle between the second branch and the target branch from the left of the first intersection in the (a) diagram or the (b) diagram of fig. 9 is 40 °,40 ° is greater than the second preset angle 35 °,40 ° is smaller than the first preset angle 45 °, at which time the first navigation interface of the (a) diagram of fig. 9 may become the second navigation interface of the (a) diagram of fig. 14, the first navigation interface of the (b) diagram of fig. 9 displayed in the AR region may become the second navigation interface of the (b) diagram of fig. 14 displayed in the AR region, the second navigation interface shown in fig. 14 (a) or (b) includes an indication icon of each of 2 branches, the 2 branches being a third branch from the left and a fourth branch from the left of the first intersection, in particular, the second navigation interface shown in fig. 14 (a) may be a navigation interface presented by the indication icon displayed in a thumbnail of the navigation map, the (b) in fig. 14 is another scene diagram of ARHUD-based navigation under the intersections of the plurality of branches, the second navigation interface displayed in the AR area in the (b) in fig. 14 may be superimposed in the actual intersection to be presented immediately in front of the user's line of sight, the electronic device may be a user-driven vehicle in fig. 14 (b) or an ARHUD device installed in the user-driven vehicle in fig. 14 (b).

Optionally, when the electronic device moves from the first position smaller than the first distance to the second position smaller than the second distance, if N-P intersections between N branches of the first intersection, where an angle between adjacent branches is larger than a second preset angle and smaller than the first preset angle, are not present, the second navigation interface includes an indication icon of each of P branches of the first intersection, where the P branches are all branches of the N branches, and the second navigation interface is similar to the first navigation interface in fig. 9 (a) or (b), so that details will not be described herein for avoiding redundancy.

Optionally, the second navigation interface includes an indication icon of each of the P branches of the first intersection, which may be understood as: the second navigation interface includes P indication icons, that is, one of the P indication icons in the second navigation interface indicates one of the P branches. For example, the second navigation interface in fig. 14 (a) or (b) includes 2 indication icons of 2 branches of the first intersection, one indication icon indicating one of the 2 branches.

Optionally, if the angle between the target switch and the adjacent switch is greater than the second preset angle, the P switches include the target switch but do not include switches adjacent to the target switch. For example, the second preset angle is 35 °, and the angle between the left-hand second branch and the left-hand third branch of the first intersection shown in fig. 14 (a) or (b) is 40 °, and the left-hand third branch is the target branch, so that the second navigation interface shown in fig. 14 (a) or (b) includes the indication icon of the target branch and does not include the indication icon of the left-hand second branch.

Optionally, after displaying the first navigation interface, the electronic device may acquire a current second position of the electronic device, and when a distance between the second position and the first intersection is smaller than the second distance, display the second navigation interface. The second navigation interface displayed in the AR area as shown in the graph (b) of fig. 14 may be a navigation interface displayed when the distance h from the second intersection of the second position of the vehicle driven by the user is smaller than the second distance after the first navigation interface displayed in the AR area in the graph (b) of fig. 9.

Alternatively, the second location may be determined by a location sensor of the electronic device.

Alternatively, the second location may be sent by other devices to the electronic device. Alternatively, the second location may be determined by a location sensor on the other device.

Alternatively, the P branches may be on the same side in the moving direction of the electronic device. Alternatively, the P branches may all be on the same side of the direction of movement of the electronic device on the current road. The P indication icons included in the second navigation interface include an indication icon of the target turnout and an indication icon of the turnout on the same side face of the target turnout in the moving direction of the electronic device, so that a user can clearly distinguish the turnout which is not on the same side face with the target turnout, that is, the second navigation interface can display the indication icons of the turnouts which are easy to be confused by the user, and therefore the second navigation interface can be presented to the user clearly and concisely, and too many indication icons are prevented from being displayed.

As shown in fig. 14 (a) or (b), the 2 branches included in the second navigation interface are a third branch from the left and a fourth branch from the left of the first intersection in the figure, and the 2 branches are all on the same side of the user-driven vehicle in the moving direction.

Optionally, if the direction of the target switch of the P switches is the moving direction of the electronic device on the current road, the second navigation interface may include an indication icon of the target switch and indication icons of switches adjacent to the target switch on the left and right sides, that is, the P switches may not be limited to be on the same side of the moving direction of the electronic device.

Optionally, in the case that the direction of the target switch in the P switches is the moving direction of the electronic device on the current road, and the second navigation interface includes an indication icon of the target switch and an indication icon of a switch adjacent to the target switch on the left and right sides, if the angle between the target switch and the adjacent switch is greater than the second preset angle, the P switches include the target switch, but do not include the switch adjacent to the target switch. For example, the second preset angle is 35 °, the first preset angle is 45 °, and the second navigation interface shown in fig. 15 (a) or (b) includes an indication icon of each of 2 branches, the 2 branches being the second branch from the left and the third branch from the left of the first intersection, specifically, the second navigation interface shown in fig. 15 (a) may be a navigation interface presented by an indication icon displayed in a thumbnail of a navigation map, the fig. 15 (b) is another scene schematic diagram of ARHUD-based navigation at intersections of a plurality of branches, the second navigation interface displayed in an AR area in fig. 15 (b) may be superimposed in front of the user's line of sight in an actual intersection, and the electronic device may be a vehicle driven by the user in fig. 15 (b) or an ARHUD device installed in a vehicle driven by the user in fig. 15 (b). In fig. 15 (b), when the distance h between the current second position of the vehicle driven by the user and the first intersection is smaller than the second distance, the second left-hand branch of the first intersection is the target branch, the direction of the target branch is the direction in which the vehicle driven by the user moves, the angle between the first left-hand branch and the target branch is 40 ° or greater than 35 °, and the angle between the third left-hand branch and the target branch is 30 °, the second left-hand branch and the third left-hand branch of the first intersection are included in the second navigation interface shown in fig. 15 (a) or (b).

Optionally, in the case that the direction of the target switch in the P switches is the moving direction of the electronic device on the current road, and the second navigation interface includes an indication icon of the target switch and an indication icon of a switch adjacent to the target switch in the left-right direction, if the angle between the target switch and the adjacent switch is smaller than or equal to the second preset angle, the P switches include the target switch and a switch adjacent to the target switch in the left-right direction, and the second navigation interface is similar to the first navigation interface in the diagrams (a) and (b) of fig. 8, so that detailed description is omitted herein for avoiding redundancy.

Alternatively, the third branch may be any one of the P branches. Alternatively, the third angle may be a vector including a magnitude and a direction, the third angle may be a positive number, which may indicate that the third branch is an uphill branch, or a negative number, which may indicate that the third branch is a downhill branch.

Optionally, the electronic device may include an ARHUD device, where a display area of the ARHUD device is an AR area of the ARHUD, the AR area is configured to display a second navigation interface, a gradient of a third branch of the P branches is a third angle, and an angle of an indication icon of the third branch of the first intersection included in the second navigation interface with respect to a road surface direction of the first intersection is the third angle, so that the indication icon of the third branch in the second navigation interface may better fit with an actual road surface.

Optionally, the arrangement manner of the P indication icons of the P branches of the first intersection in the second navigation interface may be a third arrangement manner. Optionally, if the indication icon of the fourth switch among the P switches at the first intersection is at the boundary of the display area of the electronic device, at this time, the arrangement mode of the P indication icons of the P switches in the second navigation interface is changed, and the second navigation interface may be switched to the ninth navigation interface, where the arrangement mode of the P indication icons of the P switches at the first intersection in the ninth navigation interface is a fourth arrangement mode, and in the fourth arrangement mode, any one of the P indication icons of the P switches is in the display area of the electronic device, where the third arrangement mode is different from the fourth arrangement mode. Alternatively, the first arrangement and the third arrangement may be the same or different, and the second arrangement and the fourth arrangement may be the same or different.

Optionally, when the electronic device includes an ARHUD device, the display area of the ARHUD device is an AR area of the ARHUD, where the AR area is used to display a ninth navigation interface, when the electronic device is closer to the first intersection, a range of a road that can be covered by the AR area is gradually smaller, a fourth branch of P branches of the first intersection may appear at a boundary of the AR area, and at this time, an arrangement manner of P indication icons of P branches in the second navigation interface needs to be changed, and the second navigation interface may be switched to the ninth navigation interface, so that P indication icons of P branches in the ninth navigation interface are all in the AR area. The arrangement mode of the P indication icons of the P turnouts of the first intersection in the ninth navigation interface is a fourth arrangement mode, which is different from the third arrangement mode of the P indication icons of the P turnouts of the first intersection in the second navigation interface, and any one indication icon of the P indication icons of the P turnouts is in the AR area under the fourth arrangement mode. Therefore, the indication icons of the turnout which are out of the coverage range of the AR area can still display the relative position relation with the adjacent turnout in the ninth navigation interface, so that a user is helped to distinguish the target turnout and accurately grasp the time for turning to the target turnout.

For example, in the case where the arrangement of 2 indication icons of 2 branches in the second navigation interface displayed in the AR area in fig. 14 (b) is the third arrangement, as the electronic device moves, the range of the road that the AR area may cover becomes gradually smaller, the fourth branch from the left of the first intersection in fig. 14 (b) may appear outside the range covered by the AR area, when the indication icon of 2 branches from the left appears at the boundary of the AR area in the indication icon of the fourth branch in fig. 14 (b) may become the ninth navigation interface displayed in the AR area in fig. 16, as shown in fig. 16, a scene based on ARHUD navigation under the intersections of a plurality of branches, the electronic device may be a vehicle driven by the user in fig. 16 or an ARHUD device installed in the vehicle driven by the user in fig. 16, the 2 indication icons of 2 branches in the ninth navigation interface displayed in the AR area may become the ninth navigation interface displayed at the boundary of the AR area, and the distance between the current navigation interface of 2 in the first road area (h) of the user in the navigation interface of fig. 16 is the current distance of the road 14 b.

Alternatively, the fourth branch may be any one of the P branches.

Optionally, the arrangement manner of the P indication icons may arrange the positions of the P indication icons in the display area of the electronic device, in the third arrangement manner and the fourth arrangement manner, the relative positional relationship of the P indication icons is unchanged, for example, the third arrangement manner of the P indication icons of the P branches of the first intersection in the second navigation interface is a lateral distribution, and in the ninth navigation interface, the fourth arrangement manner of the P indication icons of the P branches of the first intersection may be a longitudinal redistribution of the P indication icons that are distributed laterally, under the lateral distribution and the longitudinal distribution, for example, the relative positional relationship of the indication icons 1 and the indication icons 2 is unchanged, for example, under the lateral distribution, the indication icons 1 are on the left side of the indication icons 2, and under the longitudinal distribution, the indication icons 1 are also on the left side of the indication icons 2. For example, the arrangement of 2 indication icons of 2 branches of the second navigation interface displayed in the AR area shown in fig. 14 (b) is a third arrangement, in which the indication icon of the third branch from the left is above the indication icon of the fourth branch from the left, and the arrangement of 2 indication icons of 2 branches of the ninth navigation interface displayed in the AR area shown in fig. 16 is a fourth arrangement, in which the indication icon of the third branch from the left is above the indication icon of the fourth branch from the left.

Optionally, the display manner of the indication icon of the target switch in the P switches included in the second navigation interface may be the first display manner, and the display manner of the indication icon of the switch other than the target switch in the P switches may be the second display manner, that is, the display manner of the indication icon of each switch in the P switches included in the second navigation interface is unchanged, that is, the display manner of the indication icon of the target switch in the P switches is still the display manner of the indication icon of the target switch in the N switches in the first navigation interface, and the display manner of the indication icon of the switch other than the target switch in the P switches is still the display manner of the indication icon of the switch other than the target switch in the N switches in the first navigation interface. For example, the display mode of the indication icon of the target branch in the second navigation interface shown in fig. 14 (a) or (b) is the first display mode, and the display mode of the indication icon of the branch other than the target branch in the second navigation interface shown in fig. 14 (a) or (b) is the second display mode.

For example, as the electronic device moves on the basis of fig. 14 (a) or (b), when the electronic device moves to the first intersection, the second navigation interface in fig. 14 (a) or (b) may become the tenth navigation interface in fig. 17 (a) or (b), as the tenth navigation interface in fig. 17 (a) may be the navigation interface presented by the indication icon displayed in the thumbnail of the navigation map, the (b) in fig. 17 is a scene diagram based on ARHUD navigation under the intersections of the plurality of intersections, and the tenth navigation interface displayed in the AR area may be superimposed to be presented in front of the user's line of sight in reality, wherein the electronic device may be the vehicle driven by the user in fig. 17 (b) or the ARHUD device installed in the vehicle driven by the user in fig. 17 (b). The third display mode of the target-side instruction icon in the tenth navigation interface of fig. 17 (a) is different from the first display mode of the target-side instruction icon in the second navigation interface of fig. 14 (a), the third display mode of the target-side instruction icon in the tenth navigation interface of fig. 17 (b) is different from the first display mode of the target-side instruction icon in the second navigation interface of fig. 14 (b), and the target-side instruction icon in fig. 17 (a) or (b) is more conspicuous than the other target-side instruction icons.

Optionally, the indication icon of each turnout is an indication arrow, the direction indicated by the indication arrow of each turnout is a turnout direction of each turnout, as shown in fig. 6 to 17, the indication icon in the navigation interface is an indication arrow, and the direction indicated by each indication arrow is a turnout direction of the corresponding turnout. Therefore, the indication icons in the navigation interface not only can distinguish the target turnout from turnouts except the target turnout, but also indicate the direction of each turnout, so that the user can be better helped to distinguish the direction of the target turnout to be turned.

Alternatively, the indication icon of each turnout may be an indication icon of any shape, and the indication icons of turnouts other than the target turnout in the navigation interface have the same shape.

Alternatively, the electronic device may be a device including an ARHUD, where the display area of the ARHUD device is an AR area, and the AR area is used to display the navigation interface, that is, in a case where the electronic device includes the ARHUD device, the indication icon in the navigation interface may be superimposed on the intersection reality of a plurality of branches, and combined with the actual road condition, as shown in fig. 6 (b), fig. 7 (b), fig. 8 (b), fig. 9 (b), fig. 10 (b), fig. 11, fig. 12, fig. 13 (b), fig. 14 (b), fig. 15 (b), fig. 16, or fig. 17 (b). In this way, in the navigation process, the target turnout of the turnouts can be clearly distinguished through the indication icon which is displayed in front of the sight of the user and combined with the actual turnout, so that the user is prevented from looking at the thumbnail of the navigation map at low head to be distracted.

Optionally, when the electronic device includes an ARHUD device and performs navigation based on the ARHUD, due to limitation of the AR area, the indication icon of a certain branch in the navigation interface seen by the user may not be perfectly fit to the branch in the real scene, but the indication icon corresponding to the branch in the displayed navigation interface should be fit to the branch in the real scene as much as possible, for example, the indication icon of the fourth branch from the left of the first intersection in fig. 13 (b) is out of the coverage range of the AR area, the indication icon of the fourth branch from the left seen by the user may not be completely fit to the fourth branch from the left, but the indication icon of the fourth branch from the left in the fourth navigation interface displayed in the AR area in fig. 13 (b) is fit to the fourth branch from the left as much as possible.

The method for navigating under the scene of the intersections of the plurality of turnouts can show the shapes of the intersections of the plurality of turnouts and the relative positions of the electronic equipment and the intersections of the plurality of turnouts through the changes of the number, the direction, the relative positions and the display modes of the indication icons in the navigation interface, so that a user can drive a vehicle to more accurately grasp the time for steering the target turnout, and the user cannot walk the turnout or miss the target turnout.

Fig. 18 (a) or (b) is a schematic view of a scenario of multiple intersections provided in the embodiment of the present application, where the electronic device may be a vehicle driven by a user in fig. 18 (a) or (b) or an ARHUD device installed in a vehicle driven by a user in fig. 18 (a) or (b), when the user drives a road on which the vehicle is about to drive into multiple intersections, a road with a smaller curvature or a zero curvature, such as a straight road, as shown in fig. 18 (a), if a distance between adjacent intersections in the multiple intersections on the straight road is relatively close, or a roundabout road with a larger curvature, as shown in fig. 18 (b), if a distance between adjacent intersections in the roundabout is relatively close, it is difficult for the user to distinguish a target intersection in the thumbnail of the navigation map according to an indication icon marked in the thumbnail, at this time, the user needs to view the target intersection indicated by the indication icon in the thumbnail, and the user needs to switch between the navigation map and the actual road, so that the user easily has a potential safety hazard. In some embodiments, in order to solve the problem of potential safety hazards caused by the fact that the line of sight of the user switches back and forth between the thumbnail of the navigation map and the actual road, the indication icon may be superimposed into the actual target intersection based on the ARHUD, although the user may not need to look at the indication icon marked in the thumbnail of the navigation map, the distance between the target intersection and the adjacent intersection in the multiple intersections is closer, that is, the target intersection and the adjacent intersection are closer, then the adjacent intersection which are closer cannot be well distinguished by the indication icon, as shown in fig. 19, which is a scene diagram based on ARHUD navigation in the road with the multiple intersections having smaller curvature, wherein the electronic device may be an ARHUD device in the vehicle driven by the user in fig. 19 or in the vehicle driven by the user in fig. 19, the target intersection and the adjacent intersection are closer, and the direction of the target intersection indicated by the indication icon in the navigation interface displayed in the AR region is not able to clearly distinguish whether the target intersection is the adjacent intersection or the target intersection; or the road curvature of the road sections of the multiple intersections is large, the AR area may not completely cover the multiple intersections on the road, if the target intersection is not in the AR area, the indication icon of the target intersection displayed in the ARHUD cannot be superimposed on the actual target intersection, and further the user cannot identify the position of the target intersection according to the indication icon displayed in the ARHUD, as shown in fig. 20, a scene diagram based on ARHUD navigation in a roundabout of the multiple intersections with large curvature is shown, where the electronic device may be a vehicle driven by the user in fig. 20 or an ARHUD device installed in the vehicle driven by the user in fig. 20, and when the user drives the vehicle into the roundabout, the AR area cannot cover the target intersection on the roundabout, and the indication icon of the target intersection displayed in the ARHUD cannot be combined with the target intersection in the real scene, and the user cannot identify the target intersection in the roundabout according to the navigation interface displayed in the AR area, so that the user cannot accurately turn to the target intersection, thereby causing a wrong road junction or the target intersection to be missed.

In this regard, the embodiment of the application will provide a method for navigation, so as to improve the navigation accuracy under the scene of multiple intersections, help the user to drive the vehicle to accurately grasp the turning time, and avoid to walk wrong or miss the target intersection.

As shown in fig. 21, fig. 21 is a schematic diagram of a method 2100 for navigation provided herein, the method 2100 including:

s2110, when the electronic equipment moves to an ith intersection in R intersections, displaying a fifth navigation interface, wherein the fifth navigation interface comprises indication icons of R-i intersections, the R-i intersections are intersections except the first intersection to the ith intersection in the R intersections, the R-i intersections comprise target intersections, the intersections except the target intersections in the R intersections are intersections between the electronic equipment and the target intersections at a third position, R is a positive integer greater than or equal to 2, and the value of i is 1 to R-1.

Optionally, the third location is a current location of the electronic device.

Optionally, the electronic device may acquire the current third position of the electronic device, for example, the electronic device determines the current longitude and latitude coordinates of the electronic device through the position sensor in fig. 1, so as to obtain the current third position of the electronic device, that is, the third position may be the longitude and latitude coordinates.

Alternatively, the third location may be sent by other devices to the electronic device. Alternatively, the third location may be determined by a location sensor on the other device.

Optionally, the curvature of the road where the R intersections are located is greater than the first preset curvature. Alternatively, the first preset curvature may be user-set or preconfigured, and the first preset curvature may be empirically derived. As shown in fig. 18 (b), the road where R intersections are located is a roundabout.

Optionally, the curvature of the road where the R intersections are located is smaller than or equal to a second preset curvature. Alternatively, the second preset curvature may be user-set or preconfigured, and the second preset curvature may be empirically derived. For example, the second preset curvature is zero, and as shown in fig. 18 (a), the road where R intersections are located is a straight road.

Alternatively, i has a value of 1 to R-1, which can be understood as: along with the movement of the electronic equipment, when the value of i is 1, the electronic equipment moves to the first intersection, the displayed fifth navigation interface comprises R-1 indication icons from the second intersection to the R intersection, when the value of i is 2, the electronic equipment moves to the second intersection, the displayed fifth navigation interface comprises R-2 indication icons from the third intersection to the R intersection, and so on, when the value of i is R-2, the electronic equipment moves to the R-2 intersection, the displayed fifth navigation interface comprises 2 indication icons from the R-1 intersection to the R intersection, and when the value of i is R-1, the electronic equipment moves to the R-1 intersection, and the displayed fifth navigation interface comprises the indication icon of the R intersection, namely the indication icon of the target intersection. The values of i are different, the number of the indication icons displayed by the fifth navigation interface is different, and one icon disappears along with the electronic equipment passing through one intersection.

For example, as shown in fig. 22 (a) to (c), a scene diagram based on ARHUD navigation in roads with a plurality of intersections with smaller curvature, where the electronic device may be a vehicle driven by the user in fig. 22 (a) to (c) or an ARHUD device installed in a vehicle driven by the user in fig. 22 (a) to (c), where R is 4, i has a value of 1 to 3, when i=1, as shown in fig. 22 (a), a fifth navigation interface displayed in an AR area includes 3 indication icons of 3 intersections when the vehicle driven by the user moves to the 1 st intersection in the 4 intersections, when i=2, as shown in fig. 22 (b), a fifth navigation interface displayed in an AR area includes 2 indication icons of 2 intersections, when i=3, as shown in the 4 intersections, and when i=3, as shown in the 5 intersection moves to the 3 indication icons of the 5 intersection, i=2, as shown in the 5 interface. It should be understood that when the vehicle driven by the user moves to the ith intersection of the 4 intersections, the indication icon of the ith intersection disappears, the fifth navigation interface only comprises the indication icons of the 4-i intersections, and the value of i does not comprise the target intersection. Therefore, when the user drives the vehicle to run on the roads with the plurality of intersections with smaller curvature, the user can be reminded of the intersections between the current position and the target intersection in real time according to the dynamic change of the number of the indication icons in the fifth navigation interface which is presented in front of the sight of the user, and the user is helped to make preparation for turning the target intersection in advance.

For another example, as shown in fig. 23 (a) to (c), a scene diagram based on ARHUD navigation in a roundabout with multiple intersections, where the electronic device may be a vehicle driven by the user in fig. 23 (a) to (c) or an ARHUD device installed in a vehicle driven by the user in fig. 23 (a) to (c), where R is 4, i has a value of 1 to 3, when i=1, as shown in fig. 23 (a), a fifth navigation interface displayed in an AR area includes 3 indication icons of 3 intersections when the vehicle driven by the user moves to 1 st intersection in 4 intersections, and when i=2, as shown in fig. 23 (b), a fifth navigation interface displayed in an AR area includes 2 indication icons, and when i=3, as shown in fig. 23 (c), a fifth navigation interface includes 3 indication icons of 3 intersections, and when i=2, as shown in fig. 23 (c), a fifth navigation interface displayed in an AR area includes a fifth navigation interface. Therefore, when the user drives the vehicle to run in the rotary island, the user can be reminded of the crossing between the current position and the target crossing in real time through the dynamic change of the number of the indication icons in the fifth navigation interface which is presented in front of the sight of the user, and the user is helped to make preparations for turning to the target crossing in advance.

Optionally, the distance between any two adjacent intersections in the R-i intersections is smaller than the first preset distance, that is, the intersection which is easy to be confused can be displayed in the fifth navigation interface, so that the situation that when the indication icon of the target intersection is only displayed, the user cannot clearly distinguish the target intersection from the intersection adjacent to the target intersection when the distance between the adjacent intersections in the R-i intersections is relatively close is avoided, and therefore driving errors are caused.

For example, the first preset distance is 30m, as shown in fig. 22 (a) and 23 (a), 3 intersections included in the fifth navigation interface displayed in the AR area refer to the second intersection, the third intersection, and the target intersection, and the distance between any adjacent two of the 3 intersections is less than 30m.

Optionally, the total number of intersections included between the third position and the target intersection is L, L is a positive integer greater than or equal to R-1, the target intersection is not included in the L intersections, if there is an adjacent intersection with a distance between two adjacent intersections greater than the first preset distance in the l+1 intersections, which indicates that the two adjacent intersections are far apart, the user can clearly distinguish the two adjacent intersections in the visual field, and then the indication icon of the intersection with a distance between the two adjacent intersections greater than or equal to the first preset distance may not be included in the fifth navigation interface, so that a clearer and concise fifth navigation interface can be presented to the user, and too many indication icons are avoided from being displayed, wherein the l+1 intersections include the L intersections and the target intersection.

Optionally, the electronic device may determine R intersections, among the L intersections, where a distance between any two adjacent intersections is smaller than the first preset distance. Optionally, if a distance between a second intersection and an adjacent intersection is smaller than the first preset distance, but a distance between the second intersection and the adjacent intersection is greater than or equal to the first preset distance, the R-i intersections include the second intersection and the adjacent intersection, and may not include the adjacent intersection, and the second intersection may be any intersection of the L intersections.

Optionally, if the two intersections with the distance between adjacent intersections of the l+1 intersections being greater than or equal to the first preset distance include the target intersection, the fifth navigation interface may include an indication icon of the target intersection of the two intersections, and not include an indication icon of the other intersection of the two intersections.

For example, the first preset distance is 30m, as shown in fig. 24, a scene diagram based on ARHUD navigation in a roundabout of multiple intersections, the electronic device may be a vehicle driven by the user in fig. 24 or an ARHUD device installed in a vehicle driven by the user in fig. 24, where R is 4, the fifth navigation interface displayed in the AR area in fig. 24 is a navigation interface displayed when i=1, that is, when the vehicle driven by the user moves to the first intersection, where the distance between the second intersection and the third intersection is 25m,25m is smaller than the first preset distance, and the distance between the third intersection and the target intersection is 50m,50m is greater than the first preset distance 30m, and the user may clearly distinguish between the third intersection and the target, and the target is included in the two adjacent intersections, so the fifth navigation interface displayed in the AR area in fig. 24 may include an indication icon of the target and an indication icon of the second intersection, excluding an indication icon of the third intersection.

It should be noted that, when the distance between the adjacent intersections is greater than the first preset distance and the adjacent intersections include the target intersection, in a scenario where the plurality of intersections are a road with a smaller curvature or a plurality of intersections in a straight road, the fifth navigation interface based on ARHUD navigation is similar to the fifth navigation interface displayed in the AR area in fig. 24, and will not be described in detail herein to avoid redundancy.

Optionally, in the case that the electronic device determines R-i intersections according to the map information, the method includes: the electronic device determines R-i intersections with a distance between two adjacent intersections smaller than a first preset distance at L intersections according to the map information, that is, the electronic device may determine L intersections according to the map information, and determine R-i intersections with a distance between any two adjacent intersections smaller than the first preset distance at L intersections.

Optionally, the indication icons of the R-i intersections included in the fifth navigation interface may be indication arrows, and a direction indicated by the indication arrow of each of the R-i intersections is a direction in which the electronic device moves. It should be understood that the direction in which the electronic device moves may be the road surface direction in which the electronic device is currently moving, as shown in fig. 22 (a) to (c), the direction indicated by the pointing arrow in the fifth navigation interface displayed in the AR area is the direction in which the vehicle is moved by the user, or the road surface direction of the straight road, and as shown in fig. 23 (a) to (c), the direction indicated by the pointing arrow in the fifth navigation interface displayed in the AR area is the direction in which the vehicle is moved by the user, or the road surface direction of the rotary island.

Optionally, the indication icons of the target intersections in the indication icons of the R-i intersections included in the fifth navigation interface are displayed in a fourth display mode, and the indication icons of the intersections other than the target intersections in the R-i intersections are displayed in a fifth display mode, wherein the fourth display mode is more striking than the fifth display mode.

As shown in fig. 22 (a) to (c) or fig. 23 (a) to (c), the indication icon of the target intersection in the fifth navigation interface displayed in the AR area is displayed in a more prominent manner than the indication icon of the intersection other than the target intersection.

Optionally, the indication icon of the j-th intersection in the R-i intersections included in the fifth navigation interface is larger than the indication icon of the j+1th intersection, the value of j is a positive integer from 1 to R-i-1, and the sizes of the R-i indication icons of the R-i intersections can be set according to a certain proportion of the distance from the electronic device.

The indication arrow of the second intersection is larger than the indication arrow of the third intersection in the fifth navigation interface displayed in the AR area as shown in fig. 22 (a) and fig. 23 (a), and the indication arrow of the third intersection is larger than the indication arrow of the fourth intersection, that is, the indication arrow of the target intersection is the smallest.

Optionally, the distance between the indication icon of the j-th intersection and the indication icon of the j+1th intersection in the R-i intersections and the distance between the j-th intersection and the j+1th intersection are in a direct proportional relation, and the value of j is a positive integer from 1 to R-i-1. It should be understood that the distance between any two adjacent intersections in the R-i intersections is closer, the distance between the corresponding adjacent two indication icons in the fifth navigation interface is also closer, the distance between any two adjacent intersections in the R-i intersections is farther, and the distance between the corresponding adjacent two indication icons in the fifth navigation interface is also farther. Therefore, the user can know the distance between adjacent intersections in the plurality of intersections according to the relative positions of the indication icons in the fifth navigation interface, and the driver can know the position relationship between the current position of the electronic device and each intersection between the target intersections more clearly.

As shown in fig. 25, the electronic device may be the vehicle driven by the user in fig. 25 or the ARHUD device installed in the vehicle driven by the user in fig. 25, where R is 4, the fifth navigation interface displayed in the AR area in fig. 25 is a navigation interface displayed when i=1, that is, when the vehicle driven by the user moves to the first intersection, and the distance between the indication icon of the second intersection and the indication icon of the third intersection in the fifth navigation interface displayed in the AR area in fig. 25 is proportional to the distance between the second intersection and the third intersection, and the distance between the indication icon of the third intersection and the indication icon of the target intersection is proportional to the distance between the third intersection and the third target intersection.

It should be noted that, in the embodiment in which the distance between the indication icon of the jth intersection and the indication icon of the jth+1th intersection and the distance between the jth intersection and the jth+1th intersection are in a direct proportional relationship, in the scene of the road with a smaller curvature or the multiple intersections in the straight road, the fifth navigation interface based on ARHUD navigation is similar to the fifth navigation interface displayed in the AR area in fig. 25, and will not be described in detail here for avoiding redundancy.

Optionally, if i=1, before displaying the fifth navigation interface, the method further includes: acquiring a current third position of the electronic equipment; and when the distance between the third position and the first intersection in the R intersections is smaller than the first distance, displaying a seventh navigation interface, wherein the seventh navigation interface comprises an indication icon of each intersection in the R intersections.

Before the fifth navigation interface is displayed, when the distance between the current third position of the electronic device and the first intersection of the R intersections is smaller than the third distance, the seventh navigation interface is displayed, so that a user can identify each intersection according to the indication icons of the R intersections in the seventh navigation interface, and the user can be prompted about the number of intersections which need to be passed between the current third position and the target intersection.

Optionally, in the case that the electronic device acquires the third distance in real time, the third distance may be a product of a third preset time and a current speed of the electronic device, where the third preset time may be understood as a set time for reminding the user of the impending arrival at the first intersection in advance, the third preset time may be obtained empirically, that is, when a current third position of the electronic device is located at a distance from the first intersection that is smaller than a third distance obtained by a product of the third preset time and the current speed of the electronic device, the seventh navigation interface is displayed.

For example, as shown in a schematic view of a scenario based on ARHUD navigation in a roundabout with multiple intersections in fig. 26, the electronic device may be the vehicle driven by the user in fig. 26 or the ARHUD device installed in the vehicle driven by the user in fig. 26, and the seventh navigation interface displayed in the AR area in fig. 26 is a navigation interface displayed when the distance h from the first intersection at the current third location of the vehicle driven by the user is smaller than the third distance, where R is 4, and the seventh navigation interface includes indication icons of 4 intersections, where the 4 intersections refer to the first intersection, the second intersection, the third intersection, and the target intersection.

Note that, in the road of the plurality of intersections with the smaller curvature or the straight road of the plurality of intersections, the seventh navigation interface based on ARHUD navigation is similar to the seventh navigation interface displayed in the AR area in fig. 26, and will not be described in detail here for avoiding redundancy.

Optionally, the indication icon of each intersection of the R intersections included in the seventh navigation interface is an indication arrow, and the direction indicated by the indication arrow of each intersection of the R intersections is the direction in which the electronic device moves, so that the directions indicated by the R indication arrows all point to the direction in which the electronic device moves, and the direction indicated by the R indication arrows in the seventh navigation interface can explicitly indicate the direction of the road on which the vehicle driven by the user currently runs. Alternatively, the direction in which the electronic device moves may be the road surface direction of the road on which the electronic device is currently moving.

As shown in fig. 26, 4 indication icons of 4 intersections in the seventh navigation interface displayed in the AR area are indication arrows, and the direction indicated by the 4 indication arrows is the direction in which the vehicle driven by the user moves on the road, that is, the direction indicated by the 4 indication arrows of 4 intersections in the seventh navigation interface may be the road surface direction of the rotary island in fig. 26.

Optionally, the indication icon of the target intersection in the seventh navigation interface is displayed in a fourth display mode, the indication icons of intersections other than the target intersection in the R intersections are displayed in a fifth display mode, and the fourth display mode is more striking than the fifth display mode. Because the display mode of the indication icons of the target intersections is more striking than the display mode of the indication icons of the intersections except the target intersections, the user can identify the target intersections, so that the user can drive towards the target intersections, that is, the indication icons of the target intersections are more striking, and the user can conveniently identify the target intersections in R intersections.

As shown in fig. 26, the indication icon of the target intersection in the seventh navigation interface displayed in the AR area is displayed in a more prominent manner than the indication icons of intersections other than the target intersection, and the indication icons of intersections other than the target intersection are displayed in a uniform manner.

Optionally, the indication icon of the j-th intersection in the R intersections included in the seventh navigation interface is larger than the indication icon of the j+1th intersection in the R intersections, and the value of j is a positive integer from 1 to R-i-1. Alternatively, the sizes of the R indication icons of the R intersections may be set according to the distance of the R intersections from the electronic device.

As shown in fig. 26, the sizes of the indication icons of the first to fourth intersections in the seventh navigation interface displayed in the AR area are set from large to small, the indication icon of the first intersection is largest, and the indication icon of the fourth intersection, that is, the target intersection is smallest.

Optionally, a distance between an indication icon of a j-th intersection in the R intersections and an indication icon of a j+1th intersection in the R intersections and a distance between the j-th intersection and the j+1th intersection are in a direct proportional relation, wherein the value of j is a positive integer from 1 to R-1. That is, the distance between any two adjacent intersections in the R intersections is closer, the distance between the two adjacent indication icons corresponding to each other in the seventh navigation interface is also closer, the distance between any two adjacent intersections in the R intersections is farther, and the distance between the two adjacent indication icons corresponding to each other in the seventh navigation interface is also farther.

As shown in fig. 26, in the seventh navigation interface displayed in the AR area, the distance between the indication icon of the second intersection and the indication icon of the third intersection is closer, in practice, the distance between the indication icon of the third intersection and the indication icon of the target intersection is further, in practice, the distance between the third intersection and the target intersection is further, and so on, the relative positional relationship between the indication icons of the 4 intersections is determined according to the relative distance between the actual 4 intersections. Therefore, the user can solve the distance between corresponding intersections in R intersections according to the relative positions of the indication icons in the seventh navigation interface, and the user can be helped to know the position relationship between the current position of the vehicle driven by the user and each intersection between the target intersections more clearly.

Optionally, the seventh navigation interface is displayed at a time before the fifth navigation interface, and when the electronic device moves to the first intersection of the R intersections, the seventh navigation interface may be switched to the fifth navigation interface. For example, when the current third position of the electronic device is less than the third preset distance from the first intersection, the seventh navigation interface displayed in the AR area as in fig. 26 may be changed from the seventh navigation interface displayed in the AR area in fig. 26 to the fifth navigation interface displayed in the AR area in fig. 23 (a) as the electronic device moves to the first intersection.

Optionally, when the R intersections are intersections on roads with curvature less than or equal to the second preset curvature, intersections other than the target intersection among the R intersections belong to the same side face as the target intersection. Optionally, the road with the curvature smaller than or equal to the second preset curvature may be a road where the electronic device is located, and the intersections other than the target intersection among the R intersections and the target intersection belong to the same side surface, which may be understood as: the R intersections are on the same side of the moving direction of the electronic equipment, so that the navigation interface displays indication icons of the R intersections on the same side as the target intersection, and as the user can clearly distinguish the target intersection from intersections which are not on the same side as the target intersection, the intersections which are not on the same side as the target intersection are not displayed, that is, the navigation interface can display the indication icons of the intersections which are on the same side as the target intersection and are easily confused by the user, so that the navigation interface can be clearly and simply presented to the user, and too many indication icons are prevented from being displayed.

As shown in fig. 27, a scene diagram based on ARHUD navigation under a straight road with multiple intersections, the electronic device may be a vehicle driven by the user in fig. 27 or an ARHUD device installed in a vehicle driven by the user in fig. 27, where R is 4, that is, the total number of intersections between the current third position of the vehicle driven by the user and the target intersection is 4, the seventh navigation interface displayed in the AR area in fig. 27 is a navigation interface displayed when the current third position of the vehicle driven by the user is less than the distance h from the first intersection, the second intersection in fig. 27 is not on the same side as the target intersection, and the user can clearly distinguish the intersections not on the same side as the target intersection, so the seventh navigation interface displayed in the AR area in fig. 27 includes an indication icon of 3 intersections, excluding an indication icon of the second intersection, the 3 intersections refer to the first intersection, the third intersection and the target intersection.

S2120, when the electronic equipment passes through R-1 intersections except the target intersection, displaying a sixth navigation interface, wherein the sixth navigation interface comprises an indication icon of the target intersection.

Alternatively, the electronic device passing through R-1 intersections other than the target intersection among the R intersections may be the electronic device passing through the R-1 st intersection among the R intersections.

As shown in fig. 28, a schematic view of a scenario based on ARHUD navigation in a roundabout with multiple intersections, the electronic device may be the user-driven vehicle in fig. 28 or the ARHUD device installed in the user-driven vehicle in fig. 28, where R is 4, the sixth navigation interface displayed in the AR area in fig. 28 is a navigation interface displayed when the user-driven vehicle passes through 3 intersections other than the target among the 4 intersections, that is, when the user-driven vehicle passes through the third intersection, the sixth navigation interface includes only the indication icon of the target intersection, and the indication icon of the target intersection may be attached to the target intersection.

It should be noted that, in the road with the plurality of intersections having the smaller curvature or the straight road with the plurality of intersections, the sixth navigation interface based on ARHUD navigation is similar to the sixth navigation interface displayed in the AR area in fig. 28, and will not be described in detail here for avoiding redundant description.

Optionally, the indication icon of the target intersection included in the sixth navigation interface is an indication arrow, and the direction indicated by the indication arrow of the target intersection is the direction of the road where the target intersection is located.

As shown in fig. 28, the indication icon of the target intersection in the sixth navigation interface displayed in the AR area is an indication arrow, and the direction indicated by the indication arrow of the target intersection points to the direction of the road where the target intersection is located.

It should be understood that, in the case where the indication icon of each of the R-i intersections included in the fifth navigation interface is an indication arrow and the direction indicated by the indication arrow of each of the R-i intersections is the direction in which the electronic device moves, the direction indicated by the indication arrow of the target intersection in the fifth navigation interface is the direction in which the electronic device moves, and if the indication icon of the target intersection included in the sixth navigation interface is an indication arrow, the direction indicated by the indication arrow of the target intersection in the sixth navigation interface is the direction of the road on which the target intersection is located, that is, the direction indicated by the indication arrow of the target intersection in the fifth navigation interface is different from the direction indicated by the indication arrow of the target intersection in the sixth navigation interface, the direction of the target intersection to be steered can be indicated intuitively by the user through the change of the indication arrow of the target intersection in the fifth navigation interface to the indication arrow of the target intersection in the sixth navigation interface. For example, on the basis that the direction indicated by the indication arrow of the target intersection in the fifth navigation interface displayed in the AR area in fig. 23 (c) is the direction in which the vehicle driven by the user moves, as the electronic device moves, when the electronic device passes through the third intersection in fig. 23 (c), the fifth navigation interface displayed in the AR area in fig. 23 may be changed to the sixth navigation interface displayed in the AR area in fig. 28, and the direction indicated by the indication arrow of the target intersection in the sixth navigation interface displayed in the AR area in fig. 28 is different from the direction indicated by the indication arrow of the target intersection in the fifth navigation interface displayed in the AR area in fig. 23 (c).

Optionally, when the electronic device moves to the target intersection, the driver needs to be prompted to perform an operation of turning to the target intersection, at this time, an eighth navigation interface is displayed, the eighth navigation interface includes an indication icon of the target intersection, the indication icon of the target intersection is displayed in a sixth display mode, and the sixth display mode is different from the fourth display mode, and is more striking than the fifth display mode. Alternatively, the display mode of the indication icon of the target intersection may be changed from the fourth display mode to the sixth display mode.

Optionally, the sixth display mode is more striking than the fifth display mode, and can be understood as: the sixth display mode is more prominent than the fifth display mode or the sixth display mode is more noticeable to the user than the fifth display mode. Optionally, the sixth display mode is different from the fourth display mode, and may be understood as: when the fourth display mode and the fifth display mode are both display modes indicating the same characteristic of the icon, the sixth display mode is a display mode indicating another characteristic of the icon, for example, the fourth display mode and the fifth display mode may be both brightness display, the sixth display mode may be color display, and for example, the fourth display mode and the fifth display mode may be both brightness display, and the sixth display mode may be shape display; or the sixth display mode may be dynamic display of the indication icon, the fourth display mode and the fifth display mode are static display of the indication icon, for example, the sixth display mode is flashing display of the indication icon of the target intersection, the fourth display mode is static display of the indication icon of the target intersection, and the fifth display mode is static display of the indication icon of the intersection except the target intersection in the R-i intersections. Optionally, the sixth display mode, which is different from the fourth display mode, may include: the sixth display mode is hollow display of the indication icon, the fourth display mode is solid display, or the fourth display mode is hollow display, and the sixth display mode is solid display.

For example, on the basis that the display mode of the indication icon of the target intersection in the sixth navigation interface displayed in the AR area in fig. 28 is the fourth display mode, as the electronic device moves, when the electronic device moves to the target intersection, the sixth navigation interface displayed in the AR area in fig. 28 becomes the eighth navigation interface displayed in the AR area in fig. 29, and as a scene diagram based on ARHUD navigation in the roundabout of a plurality of intersections shown in fig. 29, the electronic device may be the vehicle driven by the user in fig. 29 or the ARHUD device installed in the vehicle driven by the user in fig. 29, wherein R is 4, the eighth navigation interface displayed in the AR area in fig. 29 is the navigation interface displayed when the vehicle driven by the user moves to the target intersection, the eighth navigation interface includes the indication icon of the target intersection, and the display mode of the indication icon of the target intersection is the sixth display mode, which is different from the fourth display mode of the indication icon of the target intersection in fig. 28.

Note that, in the road of the plurality of intersections with the smaller curvature or the straight road of the plurality of intersections, the eighth navigation interface based on ARHUD navigation is similar to the eighth navigation interface displayed in the AR area in fig. 29, and will not be described in detail here for avoiding redundancy.

Alternatively, when the electronic device moves to the target intersection, it may be switched from the sixth navigation interface to the eighth navigation interface. As shown in fig. 29, when the vehicle driven by the user reaches the target intersection, the eighth navigation interface displayed in the AR area may be switched from the sixth navigation interface displayed in the AR area shown in fig. 28.

Optionally, the electronic device may be a device including an ARHUD, and the display area of the ARHUD device is an AR area, where the AR area is used to display the navigation interface. Alternatively, the displaying of the navigation interface by the AR area may be displaying at least one of the fifth navigation interface, the sixth navigation interface, the seventh navigation interface, or the eighth navigation interface in the AR area. That is, in the case where the electronic device includes an ARHUD device, the indication icon in the above-described navigation interface may be superimposed into road facts of a plurality of intersections, as shown in fig. 22 to 29. Therefore, in the navigation process, the user can intuitively know the crossing which is possibly passed between the current position of the electronic equipment and the target crossing through the dynamic change of the indication icon displayed right in front of the sight of the user, so that the user can be prevented from having a certain potential safety hazard caused by looking at the thumbnail of the navigation map at a low head, the user can be helped to grasp the time for turning to the target crossing more accurately, and the user can not walk wrong or miss the target crossing.

Alternatively, any one of the R intersections may be an intersection of a plurality of intersections.

Alternatively, the method 500 and the method 2100 may be combined, that is, the target intersection of the R intersections in the method 2100 may be the first intersection in the method 500, and the first navigation interface in the method 500 is displayed when the current fourth location of the electronic device is at a distance from the target intersection that is smaller than the first distance in the method 500. That is, if the electronic device passes through a portion of the R intersections, the navigation interface may be displayed according to method 2100 and when the electronic device is about to reach the target intersection, the navigation interface may be displayed according to method 500. The way in which the electronic device obtains the current fourth location is referred to above as the way in which the first location is obtained. For example, as shown in a scene diagram of ARHUD navigation in a straight road with multiple intersections in fig. 30, the electronic device may be a vehicle driven by the user in fig. 30 or an ARHUD device installed in a vehicle driven by the user in fig. 30, the target intersection of the straight road in fig. 30 is a intersection with multiple intersections, when the distance h of the current position of the vehicle driven by the user from the target intersection is greater than a first distance, for example, the first intersection in fig. 30, a fifth navigation interface displayed in the AR area in fig. 22 (a) is displayed, and when the distance h of the current fourth position of the vehicle driven by the user from the target intersection is less than the first distance, a first navigation interface displayed in the AR area in fig. 30 is displayed.

Optionally, if the target intersection in the R intersections is an intersection of a plurality of intersections with a larger curvature, when the distance between the current fourth position of the electronic device and the target intersection is smaller than the first distance, the displayed first navigation interface is similar to the first navigation interface displayed in the AR area in fig. 30, and in order to avoid redundancy, detailed description will not be given here.

The method for navigating under the scene of the plurality of intersections can prompt the user of the number of intersections possibly passing between the current position of the electronic equipment and the target intersection by the way that the indication icon of the intersection disappears when the electronic equipment moves to one of the plurality of intersections, so that the user can better grasp the time for steering to the target intersection according to the number of the indication icons and the relative position relation between the indication icons, and avoid walking out of the intersection or missing the target intersection.

It should be noted that, in the middle navigation interface in the embodiment of the present application, the display mode of the indication icon may be transparency display, and the transparency of the indication icon is different in different display modes.

That is, in the embodiment of the present application, by displaying the style, the number and the azimuth of the indication icons, the future intersection morphology is prompted in the AR area, for example, the indication icons are arrows, as shown in fig. 31 (a), the indication icons of the three branches from the second to the fourth from the left of the first intersection may be displayed, the interface formed by the three indication icons may be referred to as a first navigation interface, as shown in fig. 31 (b), the indication icons of the two branches of the first intersection may be displayed, and the navigation interface formed by the two indication icons may be referred to as a first navigation interface; for another example, as shown in fig. 32, if there is a gradient (for example, an up ramp or a down ramp) in a turnout in the first intersection, then there is a gradient of the indication icon, the indication icon of the target turnout shown in fig. 32 is highlighted and there is a gradient, the target turnout is a third turnout from left, the navigation interface displays indication icons of the third turnout from left and the fourth turnout, and the navigation interface formed by these two indication icons may be referred to as a first navigation interface; for another example, when the distance between the vehicle driven by the user and the first intersection is smaller than the first distance, the indication icons from the left to the fourth turnout in the graph (a) of fig. 33 are displayed, and the navigation interface formed by the three indication icons may be referred to as a first navigation interface.

In the case of ARHUD navigation, in the embodiment of the present application, the relative positions of the vehicles driven by the user and the intersection are prompted in the AR area during the running process by indicating the real-time changes of the icon style, number and orientation. The indication icon is an arrow, for example, as shown in fig. 34 (a), the user may display indication icons of four intersections on the rotary island before the vehicle enters the rotary island, the navigation interface formed by the indication icons of the four intersections may be referred to as a seventh navigation interface, as the vehicle moves, the change of the indication icon on the seventh navigation interface is shown in fig. 34 (b), the seventh navigation interface is displayed as a first navigation interface in fig. 34 (b) before the vehicle does not enter the rotary island, the first navigation interface indicates that the vehicle turns at a fourth intersection in front, the fifth navigation interface that may be displayed when the vehicle moves to the first intersection of the rotary island after the vehicle enters the rotary island is a second navigation interface in fig. 34 (b), the second navigation interface indicates that the vehicle moves to a third intersection in front, the fifth navigation interface is displayed as a third navigation interface in fig. 34 (b) before the vehicle does not enter the rotary island, the third navigation interface indicates that the vehicle passes the fourth intersection in front of the rotary island, and the fourth navigation interface indicates that the vehicle passes the fourth navigation interface in front of the rotary island. For another example, as shown in fig. 35, indication icons of four intersections on the rotary island may be displayed, which indicates that the vehicle driven by the user turns at the fourth intersection in front, and the distance between the indication icons in the navigation interface formed by the indication icons of the four intersections is in a proportional relationship with the distance between the actual intersections, and the greater the actual distance between the two intersections is, the greater the distance between the two indication icons of the two intersections is, the smaller the actual distance between the two indication icons of the two intersections is. For another example, in the fifth navigation interface or the seventh navigation interface, the indication icon of the target intersection is displayed with a higher brightness, and the indication icon of the target intersection is displayed in a more conspicuous manner than the indication icon of the non-target intersection. In the scene based on ARHUD navigation, in the embodiment of the application, when the target intersection or the target turnout is required to be turned, the turning opportunity is reminded in the AR area through the state change of the indication icon. For example, as shown in fig. 37, when the vehicle driven by the user reaches the target intersection or the target turnout, the display manner of the indication icon may be changed from solid to hollow.
