detailed description

The basic idea of the present invention is to provide a navigation processing method based on the identifier information: after obtaining the data of the navigation route, the distance between the position and any turning point during the data travel of the user according to the navigation route is less than a predetermined When the distance limit is used, the user is prompted by the marker information in the line of sight at the turning point to assist the user in navigating to reduce the yaw rate and improve the user's navigation experience. The navigation processing method is widely applicable to various navigation situations such as walking navigation, outdoor navigation, indoor navigation, and the like.

FIG. 1 is a schematic view showing one example reflecting the general inventive concept of the present invention.

Referring to Fig. 1, assuming that the user travels to a position close to the intersection of two roads, the intersection is a node that the user needs to make a turn, and there are a plurality of buildings (A, B, ..., F) around the road. According to the existing navigation technology, the navigation prompt is “turn left in front of the road”, and it can be seen that only the turn information based on the intersection is provided to the user. Under the premise that the user is unfamiliar with the road, only after a certain period of travel can the route be found to be correct.

In contrast, according to the basic idea of the present invention, the navigation prompt that is ultimately provided to the user is "Left turn left, you will see G". Since the building G is an intuitive and eye-catching identifier that is easily observed by the user, providing the marker information can help the user confirm that the current route is correct, thereby providing the user with a more optimized navigation experience.

A navigation processing method according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Embodiment 1

2 is a flow chart showing a navigation processing method according to Embodiment 1 of the present invention. The method can be performed on a navigation device or a mobile terminal device, such as a smart phone.

Referring to FIG. 2, in step S210, data of the navigation route is acquired according to the navigation instruction of the user, and the data of the navigation route includes data of the traveling road segment and its turning point and the prompt information of the turning point, and the prompt information of the turning point includes the line of sight at the turning point. Information on the identifiers in the range.

Here, the navigation instruction includes at least departure point information and destination information. In a specific implementation manner, the departure location information and the destination information may be information input by the user on the interaction interface of the navigation software, for example, and the departure location information may also be acquired by the mobile terminal device or the navigation device with the built-in GPS positioning device. User's current GPS coordinate data.

The data of the navigation route returned by the traditional navigation technology only includes the traveling road segment and Turning point. Typically, the turning point is a node that indicates that the user's direction of travel needs to change. For example, users often hear "turn 200 meters ahead" when using navigation.

The data of the navigation route according to the embodiment of the present invention includes, in addition to the above data, data of the prompt information to which the marker information in the line of sight range of the turning point is added. Here, the identifiers are explained. The markers refer to the buildings or scenic spots around the road. In practical applications, buildings such as Chaoyang Joy City, Baidu Building, and Bird's Nest can be used as markers to assist users in navigation. . Correspondingly, the information of the identifier may be, for example, but not limited to, the name, location, text description of the identifier, social and economic attributes such as business, education, height, width, number of layers, and the like.

Specifically, the prompt information of the turning point may include, but is not limited to, at least two kinds of information: steering information, name information of the identifier, and orientation information of the identifier with respect to the turning point. In a specific implementation manner, for example, the prompt information of the turning point is “left 200 meters ahead, building A on your right side”, visible, including the “left turn” steering information, “the right side exists The identifier name information of the building A" and the orientation information of the marker relative to the turning point. For another example, the prompt information of the turning point is "Left turn ahead, you will see Building B", which includes the "left turn" turn information and the "Building B" tag name information.

In step S220, navigation is performed according to the data of the navigation route, and the prompt information of the turning point is provided to the user.

According to an exemplary embodiment of the present invention, step S220 may include: turning to the point when it is detected that the distance between the current location and any of the turning points is less than a predetermined distance limit and is currently traveling toward the turning point A prompt message is provided to the user. That is to say, when the user is heading to any turning point, the prompt information of the turning point is prompted to the user in advance. For example, if the distance between the current location and a turning point is less than 50 meters, then the user is reminded. For example, the voice prompt "turn left on the road ahead, you will see Building B." However, it should be understood that other manners may be employed, such as displaying a preset identifier prompt icon on the interactive interface of the navigation software, or demonstrating the marker light on the terminal display screen, or using voice, visual display, touch, etc. Any combination of modes to inform the user of the content of the navigation guide.

The navigation processing method of the embodiment of the present invention can be based on the number of navigation routes during the navigation process According to the prompt information of the turning point, the user is prompted to give the marker information within the line of sight at the turning point when the user approaches the turning point, thereby reducing the yaw rate of the user. In addition, the user can determine whether the direction of travel is correct according to the information of the identifier, thereby improving the user navigation experience.

Embodiment 2

3 is a flow chart showing a navigation processing method according to a second embodiment of the present invention. The method can be performed on a navigation server.

Referring to FIG. 3, in step S310, data of a navigation route is generated according to the navigation request, and the data of the navigation route includes data of the traveling road segment and its turning point.

Specifically, as described in the foregoing embodiment, the navigation request may include at least the departure location information and the destination information. After obtaining the departure location information and the destination information, the navigation server performs navigation route planning according to the two. The planning process is a process of dividing the navigation route into a traveling road segment, and the node connecting each traveling route is a turning point.

In practical applications, the travel section is usually an extended road, and the turning point is usually the location where the bifurcation point appears, such as an intersection, a T-junction, and the like. FIG. 4 is a diagram showing an exemplary schematic diagram of an application scenario of a navigation processing method according to Embodiment 2 of the present invention. Referring to FIG. 4, in a certain navigation scene, the departure place is a place near the Joy City of Chaoyang, Beijing, and the destination is Baidu Science and Technology Park Building No. 1. Scheme 1, Scheme 2 and Scheme 3 in the figure are the data of the navigation route.

In step S320, the traveling directions of the traveling sections are respectively determined according to the data of the traveling sections, and the line-of-sight range areas at the turning points in the traveling direction are respectively acquired.

In addition to determining the direction of travel according to the data of the traveling section, the direction of travel of the traveling section can be determined by the direction sensor built in the mobile terminal device, and then fed back to the navigation server, and the navigation server can further process according to the obtained traveling direction.

Accordingly, according to an exemplary embodiment of the present invention, the processing of respectively acquiring the line-of-sight range area at the turning point in the traveling direction in step S320 may include forming a ray of a predetermined length in the traveling direction with the turning point as an end point, The first set angle is rotated leftward and rightward around the ray to form a planar sector area, and the plane sector area is used as a line of sight range area.

For example, the first set angle can be set to an angle that conforms to the line of sight of the human eye (eg, 45 degrees), and a sector area can be obtained after the ray and the left and right rotation angles are determined. This sectoral area is two-dimensional. Specifically, in the subsequent step, the plane sector area is identified according to the foregoing The selection of objects, the processing of the selection will be described in detail later. Here, for the highest selected marker, the user may not see it at all. For example, suppose there is a building M with a height of 10 meters 200 meters from the human eye. If there is a building N with a height of more than 5 meters at a distance of 100 meters from the human eye, and the building M and the building N are located. On a straight line, the user can't see the building M at this time.

Thus, the above problems can be transformed into a mathematical problem. First draw a right-angled triangle with a right-angled edge on the line where the building M, the building N, and the human eye are located. The building M is equivalent to the other right-angled side in the vertical direction. It is well known that light travels in a straight line, and the light that enters the human eye at the highest point of the building M is the oblique side of the right triangle. Since the building M is 200 meters from the human eye and the building N is 100 meters from the human eye, the building N corresponds to the median line of the above-mentioned right-angled triangle in the vertical direction according to the triangular median line theorem. Obviously, when the height of the building N exceeds 5 meters, it will block the light emitted by the building M, so that the user can not see it. Therefore, the highest identifier provided to the user at this time has no value at all.

In order to ensure that the presented marker information is visible to the user, it is necessary to consider the viewing angle of the human eye, that is, to extend from the aforementioned two-dimensional space to the three-dimensional space. Therefore, according to another exemplary embodiment of the present invention, the processing of respectively acquiring the line-of-sight range area at the turning point in the traveling direction in step S320 may further include: rotating the plane sector area upward in the direction perpendicular to the ground direction, The angle is set to form a three-dimensional sector area, and the three-dimensional sector area is used as a line of sight range area. In practical applications, the second set angle can also be set to an angle that conforms to the line of sight of the human eye (eg, 45 degrees).

In step S330, information of the identifier in the line-of-sight range area is respectively acquired from the preset identifier information database.

According to an exemplary embodiment of the present invention, step S330 may include: acquiring height data and/or position information of all the identifiers located in the planar sector area or the solid sector area from the preset identifier information database, according to the height data and/or The location information selects the information of the highest and/or most recent identifier.

Specifically, on the one hand, for the process of selecting the highest identifier, all the identifiers may be sorted according to the height data, and the identifier corresponding to the maximum value in the height data is selected. On the other hand, for the process of selecting the most recent marker, each identifier can be calculated based on the location information. The distance data of the object from the turning point, and the information of the identifier corresponding to the minimum value in the distance data is selected. In addition, the identifier may be selected according to two parameters of height and distance of the identifier, for example, the height and the distance of the identifier are respectively weighted and summed, and the identifier is selected according to the size of the value obtained by the weighted summation.

In step S340, the prompt information of the turning point is respectively generated according to the data of the turning point and the information of the marker, and the prompt information is added to the navigation data respectively.

According to an exemplary embodiment of the present invention, step S340 may include: generating at least two pieces of information according to the data of the turning point and the information of the identifier: steering information, name information of the identifier, and orientation of the marker with respect to the turning point Information about the turning point of the message. For example, you can generate a voice prompt message "Turn 200 meters ahead, there is a building A on your right side", including the "Left Turn" turn information, and the "Building A on the Right Side" logo name information. And the orientation information of the marker relative to the turning point. For another example, you can generate a message “Left road ahead, you will see Building B”, which includes the “left turn” turn information and the “Building B” marker name information.

At step S350, data of the navigation route is provided in response to the navigation request.

Through the processing of the foregoing steps S310 to S340, data of the navigation route to which the hint information of the turning point is added is obtained to be provided to the user for assisting navigation.

Further, the above navigation processing method may further include: if the deviation from the traveling direction is detected, acquiring the deviation angle data, and correcting the prompt of the traveling direction according to the deviation angle data.

FIG. 5 is a second schematic diagram showing an application scenario of the navigation processing method according to the second embodiment of the present invention, which shows a street view of the starting position of the navigation route scheme 2 shown in FIG. 4, including a north street view and a south street view. East Street View and West Street View.

Assuming that the user's current location is facing the west, the user can see the west streetscape. In the current line of sight area, the tallest building is the Golden Thai Building, located on the right side of the road. The starting point given by the actual navigation route should be northward. What should be seen is the northern streetscape. In the area of sight, the tallest building is Chaoyang Joy City, which is located on the right side of the road. At this time, the navigation will detect that the user deviates from the direction of travel, and further gives a prompt according to the obtained deviation angle data. For example, the voice prompt “The current heading direction is wrong, please turn 90 degrees to the right, and you will see Chaoyang Joy City. Located on the right side of the road to help users confirm the correct Travel direction and return to the navigation route.

The navigation processing method provided by the embodiment of the present invention generates data of the navigation route by using a navigation request, determines a traveling direction on the traveling road segment according to data of the traveling road segment in the data of the navigation route, and obtains a line of sight range at the turning point in the traveling direction. The area further obtains the marker in the line of sight range, and adds a warning including the marker information to the navigation route data for the problem of "high user yaw rate" and "cannot quickly confirm whether the traveling direction is correct when turning the point" The point prompt information is significantly different from the existing navigation route data that simply includes the traveling section and the turning point. The user is guided by the prompt information with the marker reference to follow the accurate direction of travel, so that the user has a better and more convenient navigation experience. At the same time, due to the intuitive and easy-to-understand characteristics of the marker information, the user yaw rate is greatly reduced.
