Reference is now made to fig. 2, which is a flowchart illustrating a map interface presentation method that may be used with a computer device, according to an exemplary embodiment. The computer device may be a terminal installed with an electronic map application program, or may also be a server corresponding to the electronic map application program. As shown in fig. 2, the map interface display method may include the following steps:

and step 21, displaying a map interface, wherein the map interface is used for displaying the electronic map.

The map interface may be an application interface of an electronic map application.

Step 22, responding to the instruction for displaying the target path in the map interface, and acquiring the coordinates of each candidate point; the candidate points include points on the target path and mark points corresponding to the target path.

The point on the target path may be a point determined based on a marker line corresponding to the target path.

In this embodiment of the application, when a user performs a path query operation in a map interface, or after performing the path query operation (for example, the user needs to view a planned complete path in a navigation process), the electronic map application may receive an instruction to display a target path.

And step 23, acquiring a coordinate adjustment reference value based on the coordinates of each candidate point.

In an embodiment of the present application, the coordinate adjustment reference value may include at least one of a latitude adjustment reference value and a longitude adjustment reference value.

Step 24, acquiring N target points from each candidate point; the N target points are points near the edge of the target area where each candidate point is located; n is an integer greater than or equal to 2.

In a possible implementation manner, the target area where each candidate point is located refers to an area that includes all candidate points in each candidate point.

In a possible implementation manner, the target area where each candidate point is located refers to an area including a part of candidate points in each candidate point.

For example, the target region where each candidate point is located may be a minimum region including a specified proportion (for example, 80%) of candidate points in each candidate point; alternatively, the target area where each candidate point is located may be a minimum area including a candidate point whose longitude and/or latitude satisfy a certain condition among the candidate points.

Step 25, obtaining the coordinates of the N virtual points based on the coordinate adjustment reference value and the coordinates of the N target points; the N virtual points correspond to the N target points one by one; and the relative direction of the virtual point and the corresponding target point is opposite to the relative direction of the corresponding target point and the target area.

In this embodiment, the application program of the electronic map class may adjust the coordinates of the N target points in the direction out of the target area based on the coordinate adjustment reference value, and obtain a virtual point farther from the target area than the N target points.

Step 26, displaying the electronic map containing the mark line of the target path in the map interface based on the coordinates of the N virtual points; the N virtual points are located within a viewable area of the map interface.

For example, please refer to fig. 3, which illustrates a schematic diagram of a virtual point determining and displaying process according to an embodiment of the present application. As shown in fig. 3, in response to the instruction for showing the target path, the electronic map application determines candidate points 31, where the candidate points 31 are located in an area 32 (corresponding to the target area). The electronic map application determines at least 2 target points 33 near the edge of the area 32 from the candidate points 31, adjusts the coordinates of the target points 33 in the direction outside the area 32 based on the coordinate adjustment reference value 34, obtains virtual points 35 corresponding to the target points 33 one by one, and displays the electronic map in the map interface 36 based on the virtual points 35 so that the virtual points 35 are located in the visible area in the map interface 36.

As shown in fig. 3, since the electronic map application displays the electronic map based on the virtual point 35, and the virtual point 35 is obtained by adjusting the coordinates of the target point at the edge of the area where the candidate point is located outward, when each virtual point 35 is located in the visible area of the map interface 36, each candidate point 31 in the area 32 is also correspondingly gathered to the center of the map interface 36, so as to prevent the overlay control 37 at the edge of the map interface 36 from blocking each candidate point 31 in the area 32 as much as possible.

The area 32 where each candidate point shown in fig. 3 is located is a rectangular area, and optionally, the area where each candidate point 31 is located may also be an area with other shapes, such as a circular area, and the like, which is not limited in this embodiment of the application.

To sum up, in the embodiment of the present application, the electronic map application program determines, through the coordinates of each candidate point corresponding to the target path, at least 2 target points close to the edge in each candidate point, and the coordinate adjustment reference value, and determines, based on the coordinate adjustment reference value, at least 2 virtual points farther away from the aggregation area of each candidate point on the basis of the coordinates of at least 2 target points, when the target path is displayed, so that at least 2 virtual points are located in the visible area of the map interface, on one hand, the virtual points are determined through the coordinate adjustment reference value obtained from the coordinates of each candidate point, and the target point of each candidate point, so as to appropriately reduce the scale of the electronic map and ensure the accuracy of the electronic map, on the other hand, because the overlay control in the map interface is usually located in the edge area of the map interface, therefore, through the scheme, each candidate point corresponding to the target path can be prevented from being shielded by the superposition control as much as possible; therefore, the scheme can ensure the precision of the electronic map and simultaneously avoid each candidate point corresponding to the target path from being shielded, thereby improving the display effect of the electronic map on the target path.

The method and the device for displaying the path can be used in any electronic map application program which needs to display the path and contains the overlay control in the interface.

Please refer to fig. 4, which is a flowchart illustrating a map interface presentation method according to an exemplary embodiment. The map interface display method can be used for computer equipment. The computer device may be a terminal installed with an electronic map application program, or may also be a server corresponding to the electronic map application program. As shown in fig. 4, the map interface display method may include the following steps:

step 401, displaying a map interface, where the map interface is used for displaying an electronic map.

In the embodiment of the application, when the user opens the electronic map application, the electronic map application can open a map interface, and the map interface comprises an electronic map displayed according to a certain proportion.

Generally, the map interface may also include overlay controls. The overlay control may be a control for operating an electronic map-like application, such as a zoom control, a refresh control, a positioning control, a navigation trigger control, an address query control, an address input box control, and so on.

Alternatively, the overlay control may also be a control for presenting information, for example, an information box for presenting prompt information, and the like.

Step 402, responding to an instruction for displaying a target path in the map interface, and acquiring coordinates of each candidate point; the candidate points include points on the target path and mark points corresponding to the target path.

In the embodiment of the application, when the electronic map application has a display requirement (which may be triggered by a user or actively triggered by the electronic map application), the electronic map application may obtain each candidate point corresponding to the target path.

Wherein the candidate points include points on the target path. For example, the electronic map application may sample from the target path at certain intervals to obtain a point on the corresponding target path in each candidate point.

The electronic map application program may also select key points on the target path, such as POI interest points, e.g., intersection location points, signal light location points, bus stops, subway station entry points, etc., as points on the corresponding target path in each candidate point.

In a possible implementation manner, the electronic map application may select a mark point near the target path as a mark point of a corresponding target path in each candidate point. For example, the electronic map application may select a marked point with a distance to the target path smaller than a distance threshold (e.g., 200 meters) as a marked point on the corresponding target path in each candidate point.

In a possible implementation manner, among the candidate points, a location point that can be set in the electronic map by the user is further included. For example, each of the candidate points may further include a location point set or shared by the current user or a friend user of the current user in the electronic map.

Step 403, obtaining a coordinate adjustment reference value based on the coordinates of each candidate point.

In a possible implementation manner, the obtaining a coordinate adjustment reference value based on the coordinates of each candidate point includes:

acquiring a latitude adjustment reference value in the coordinate adjustment reference value based on the maximum value of the latitude of each candidate point and the minimum value of the latitude of each candidate point;

and acquiring a longitude adjustment reference value in the coordinate adjustment reference values based on the maximum value of the longitudes of the respective candidate points and the minimum value of the longitudes of the respective candidate points.

The electronic map application program may obtain the latitude adjustment reference value in the coordinate adjustment reference values according to the maximum value of the latitude of each candidate point and the difference between the minimum values of the latitude of each candidate point.

For example, the electronic map type application may directly use the difference between the maximum value of the latitude of each candidate point and the minimum value of the latitude of each candidate point as the latitude adjustment reference value in the coordinate adjustment reference values.

For another example, the electronic map application may also multiply the difference between the maximum value of the latitude of each candidate point and the minimum value of the latitude of each candidate point by an adjustment coefficient (e.g., 0.8 or 1.2, etc.), so as to obtain the latitude adjustment reference value in the coordinate adjustment reference values.

The electronic map application program may obtain the longitude adjustment reference value of the coordinate adjustment reference values according to the maximum value of the longitude of each candidate point and the difference value between the minimum values of the longitude of each candidate point.

For example, the electronic map type application may directly take a difference between a maximum value of the longitudes of the respective candidate points and a minimum value of the longitudes of the respective candidate points as the longitude adjustment reference value among the coordinate adjustment reference values.

For another example, the electronic map application may also multiply a difference between a maximum value of the longitude of each candidate point and a minimum value of the longitude of each candidate point by an adjustment coefficient to obtain a longitude adjustment reference value in the coordinate adjustment reference values.

Step 404, acquiring N target points from each candidate point; the N target points are points near the edge of the target area where each candidate point is located; n is an integer greater than or equal to 2.

In a possible implementation manner, the N target points may be 2 or more than 2 points close to two edges of the target area in each candidate point.

For example, taking the target area as a rectangular area as an example, the N target points are 2 or more than 2 points respectively close to the left and right edges of the rectangular area in each candidate point, that is, some points are close to the left edge of the rectangular area, and the other points are close to the right edge of the rectangular area. Alternatively, the N target points are 2 or more points that are respectively close to the upper and lower edges of the rectangular region, among the candidate points.

In another possible implementation manner, the N target points may be 3 or more than 3 points of three edges close to the target area in each candidate point.

For example, taking the target area as a triangle area as an example, the N target points are 3 or more than 3 points that are respectively close to three sides of the triangle area among the candidate points. That is, each of the triangular regions corresponds to at least one of the N target points.

In another possible implementation manner, the N target points may be 4 or more than 4 points close to four edges of the target area in each candidate point.

For example, taking the target area as a rectangular area as an example, the N target points are 4 or more than 4 points that are respectively close to four sides of the rectangular area in each candidate point, that is, each of the N target points corresponds to at least one of the N target points.

In a possible implementation manner, the obtaining N target points from each candidate point includes:

acquiring a first target point which is positioned on the left of the lower part of the target area from each candidate point;

acquiring a second target point which is positioned on the lower left part of the target area from each candidate point;

acquiring a third target point which is positioned on the right of the lower part of the target area from each candidate point;

acquiring a fourth target point which is positioned at the lower right part of the target area from each candidate point;

and acquiring a fifth target point positioned at the top of the target area from each candidate point.

The positions of the first target point, the second target point, the third target point, the fourth target point and the fifth target point may overlap.

In this embodiment, in order to make the candidate points in each direction not be blocked by the overlay control as much as possible, in this embodiment, the electronic map application may determine at least two target points from the lower left and lower right of the aggregation area of each candidate point, and determine at least one target point from the top.

In a possible implementation manner, the obtaining a first target point located on a lower left side of the target area from the candidate points includes:

obtaining the point with the minimum latitude from each candidate point to obtain a minimum latitude point set; and taking at least one point with the minimum latitude point in the minimum latitude point set as the first target point.

In a possible implementation manner, the at least one point with the smallest latitude point in the minimum latitude point set refers to at least one point arranged in front of the points in the minimum latitude point set after the points are arranged in the order of longitude from small to large.

In the embodiment of the present application, there may be a plurality of points due to the latitudinal minimum point among the respective candidate points. For example, please refer to fig. 5, which shows a schematic diagram of candidate point distribution according to an embodiment of the present application. As shown in fig. 5, in the target area 50, the minimum latitude points include 3 candidate points 51, 52 and 53, and when determining the first target point on the left lower side of the target area, the electronic map application acquires the minimum latitude point set formed by the candidate points 51, 52 and 53, then arranges the candidate points 51, 52 and 53 in the order of longitude from small to large, and takes one or more of the previously arranged points as the first target point; for example, the electronic map application takes the candidate point 51 as the first target point.

In a possible implementation manner, acquiring a second target point located below the left portion of the target area from the candidate points includes:

acquiring a point with the minimum longitude in the first candidate point set to obtain a minimum longitude point set; taking at least one point with the minimum latitude in the minimum longitude point set as the second target point; the first candidate point set is a set of all or some of the respective candidate points.

In a possible implementation manner, the at least one point with the smallest latitude in the minimum longitude point set refers to at least one point arranged in front of the points in the minimum longitude point set after the points are arranged in the order from the smallest to the largest in latitude.

In the embodiment of the present application, there may be a plurality of points in the first candidate point set with the smallest longitude. For example, the first candidate point set is a set formed by all the points in the candidate points; as shown in fig. 5, in the target area 50, the minimum longitude points include 2 candidate points 54 and 55, and when determining a second target point below the left of the target area, the electronic map application acquires a minimum longitude point set formed by the candidate points 54 and 55, then arranges the candidate points 54 and 55 in order of ascending latitude, and selects one or more of the previously arranged candidate points as the second target point; for example, the electronic map type application takes the candidate point 55 as the second target point.

In one possible implementation, the coordinate adjustment reference value comprises a latitude adjustment reference value;

the first candidate point set is a set formed by candidate points of which the latitude is smaller than the sum of the minimum latitude and the first latitude increment in each candidate point; the first latitude increment is a product between the latitude adjustment reference value and a first latitude increment ratio; the first latitude increment ratio is less than 1 and greater than 0; the minimum latitude is the minimum of the latitudes of the respective candidate points.

In the embodiment of the present application, in order to make the second target point located at the lower left position as much as possible, the first candidate point set may be a point set including points at the lower part of the target area. For example, referring to fig. 5, the dividing line 50a divides the target area 50 into an upper part and a lower part, wherein the area of the target area 50 below the dividing line 50a is the lower part of the target area, the latitude of the dividing line 50a is the sum of the minimum latitude and the first latitude increment, and the minimum latitude is the minimum latitude of each candidate point in the target area 50 (i.e. the latitudes of the candidate point 51, the candidate point 52 and the candidate point 53). As shown in fig. 5, in the lower portion of the target area, the minimum longitude point includes 2 candidate points 56 and 57, and in another exemplary scheme of the present application, when determining a second target point lower than the left portion of the target area, the electronic map application may also obtain a minimum longitude point set formed by the candidate points 56 and 57, and then arrange the candidate points 56 and 57 in order from small to large in latitude, and take one or more of the previously arranged points as the second target point; for example, the electronic map type application takes the candidate point 57 as the second target point.

In a possible implementation manner, the obtaining a third target point located on a lower right side of the target area from the candidate points includes:

and taking at least one point with the largest degree in the minimum latitude point set as the third target point.

In a possible implementation manner, the at least one point with the highest degree in the minimum latitude point set refers to at least one point arranged behind the points in the minimum latitude point set after the points are arranged in the order of longitude from large to small.

For example, as shown in fig. 5, when determining a third target point on the lower side of the target area, the electronic map application program obtains a minimum latitude point set formed by the candidate points 51, 52 and 53, then arranges the candidate points 51, 52 and 53 in order of longitude from large to small, and takes one or more of the previously arranged points as the third target point; for example, the electronic map application takes the candidate point 53 as the third target point.

In a possible implementation manner, the obtaining a fourth target point located below the right of the target area from the candidate points includes:

acquiring a point with the largest longitude in the second candidate point set to acquire a maximum longitude point set; taking at least one point with the minimum latitude in the maximum longitude point set as the fourth target point; the second candidate point set is a set of all or some of the respective candidate points.

In a possible implementation manner, the at least one point with the smallest latitude in the maximum longitude point set refers to at least one point arranged in front of the points in the maximum longitude point set after the points are arranged in the order from the smallest to the largest in latitude.

In the embodiment of the present application, there may be a plurality of points in the second candidate point set with the largest longitude. For example, the second candidate point set is a set formed by all the points in the candidate points; as shown in fig. 5, in the target area 50, the points with the largest longitude include 2 candidate points 58 and 59, respectively, and when determining the fourth target point below the right of the target area, the electronic map application program obtains the minimum longitude point set formed by the candidate points 58 and 59, then arranges the candidate points 58 and 59 in the order from small to large in latitude, and takes one or more of the previously arranged points as the fourth target point; for example, the electronic map application takes the candidate point 59 as the fourth target point.

the second candidate point set is a set formed by candidate points with latitude smaller than the sum of the minimum latitude and a second latitude increment in each candidate point; the second latitude increment is a product between the latitude adjustment reference value and a second latitude increment ratio; the second latitude increment ratio is less than 1 and greater than 0; the minimum latitude is the minimum of the latitudes of the respective candidate points.

In the embodiment of the present application, in order to enable the fourth target point to be located at the lower right position as much as possible, the second candidate point set may be a point set including points at the lower part of the target area. For example, taking the second latitude increment as the same as the first latitude increment, or the ratio of the second latitude increment as the ratio of the first latitude increment as the same, please refer to fig. 5, the latitude where the dividing line 50a is located is the sum of the minimum latitude and the second latitude increment. As shown in fig. 5, in the lower portion of the target area, the point with the largest longitude includes 2 candidate points 510 and 511, and in another exemplary scheme of the present application, when determining the fourth target point below the right portion of the target area, the electronic map application may also obtain the largest longitude point set formed by the candidate points 510 and 511, and then arrange the candidate points 510 and 511 in order from the smallest latitude to the largest latitude, and take the one or more previously arranged points as the second target point; for example, the electronic map application takes the candidate point 510 as the second target point.

In a possible implementation manner, the obtaining a fifth target point located at the top of the target area from the candidate points includes:

acquiring at least one point with the largest latitude in the third candidate point set as the fifth target point; the third candidate point set is a set of all or some of the respective candidate points.

When the point with the largest latitude in the third candidate point set includes two or more points, the electronic map application may determine the fifth target point according to a preset policy (for example, according to longitude from large to small or from small to large), or may randomly select at least one point in the third candidate point set as the fifth target point.

For example, the third candidate point set is a set formed by all the points in the candidate points; as shown in fig. 5, in the target area 50, the points with the largest latitude include 2 candidate points 512 and 513, and when determining the fifth target point located at the top of the target area, the electronic map application acquires at least one of the candidate points 512 and 513 as the fifth target point. For example, the electronic map application may randomly acquire one of the candidate points 512 and 513 as the fifth target point.

In one possible implementation, the third candidate point set is a set of the respective marked points.

In an exemplary aspect of the embodiment of the application, when determining the fifth target point located at the top of the target area, the electronic map application may also select at least one point with the largest latitude from a set of marked points as the fifth target point.

In the above-mentioned solution of the embodiment of the present application, at least 5 target points of a lower left corner (a first target point, a second target point), a lower right corner (a third target point, a fourth target point) and a top (a fifth target point) of a target area are determined as an example for description. In other possible schemes, the positions of the at least 5 target points may also be located at other positions, for example, the first target point and the second target point may be located at the upper left corner of the target area, the third target point and the fourth target point may be located at the upper right corner of the target area, and the fifth target point may be located at the lower part of the target area; alternatively, the first target point and the second target point may be located at the upper left corner of the target area, the third target point and the fourth target point may be located at the lower left corner of the target area, the fifth target point may be located at the right part of the target area, and so on.

In step 405, the adjustment ratio is obtained.

In one possible implementation manner, the adjustment ratio may be obtained based on position information of a superimposed icon included in the map interface, a size of the superimposed icon, and a size of the map interface.

Because there may be differences in the sizes and layouts of the overlay icons in the map interface in different terminal models and different application versions, in the embodiment of the present application, in order to avoid as much as possible that the positions of the candidate points are blocked by the overlay icons when the electronic map is displayed, and at the same time, to ensure the maximization of the display scale of the electronic map (that is, to ensure the accuracy of the electronic map), the electronic map application may determine the adjustment ratio used for subsequently adjusting the coordinates of the target point based on the positions and sizes of the overlay icons in the current map interface and the size of the map interface.

In one possible implementation, the electronic map application may determine, based on the position, size, and size of the superimposed icon in the current map interface, the proportion of the superimposed icon to the left side of the map interface (i.e., the distance between the right edge of the superimposed icon on the left side of the map interface and the left edge of the map interface, the proportion of the width of the map interface), the proportion of the superimposed icon to the right side of the map interface (i.e., the distance between the left edge of the superimposed icon on the right side of the map interface and the right edge of the map interface, the proportion of the width of the map interface), the proportion of the superimposed icon to the lower side of the map interface (i.e., the upper edge of the superimposed icon on the lower side of the map interface, the distance between the upper edge of the map interface and the lower edge of the map interface, the proportion of the height of the map interface), and the proportion of the superimposed icon to the upper side, the distance from the upper edge of the map interface to the height of the map interface), and determining the adjustment ratio according to at least one of the four obtained proportions.

For example, taking the example of determining the above adjustment ratio based on the proportion of the superimposition icon on the lower side of the map interface, assuming that the proportion of the superimposition icon on the upper side of the map interface is 1/5, the electronic map type application may set the adjustment ratio to 20%.

In one possible implementation, the adjustment ratio may be queried based on device information of a terminal that presents the map interface.

In a possible implementation of the embodiment of the application, the electronic map application may also set corresponding adjustment ratios for various terminals respectively (for example, preset by a developer), and store corresponding terminal information (for example, terminal manufacturers and models) of the various terminals, and the electronic map application may acquire the terminal information of the current terminal during the operation process, and query the pre-stored adjustment ratios according to the terminal information.

In one possible implementation, the adjustment ratio set in advance may be acquired.

In another possible implementation of the embodiment of the present application, the electronic map application may also obtain a preset and unified fixed adjustment ratio.

Step 406, obtaining coordinates of the N virtual points based on the coordinate adjustment reference value and the coordinates of the N target points; the N virtual points correspond to the N target points one by one; and the relative direction of the virtual point and the corresponding target point is opposite to the relative direction of the corresponding target point and the target area.

the obtaining the coordinates of the N virtual points based on the coordinate adjustment reference value and the coordinates of the N target points includes:

Based on the above solution of the present application, in an exemplary solution of the present application, the electronic map application may determine the target point and the virtual point by finding a pole and calculating a corresponding virtual point.

For example, the electronic map application traverses all markers and polygon to find the following points:

1) the bottom left most corner point (point 1 where lat is the smallest and point2 where lng is the smallest, both may be the same point);

the point1 (the first target point) with the lowest lat at the bottom left corner is the point with the lowest lat and the lowest lng; the point2 (second target point) at the bottom left corner with the smallest lng is the point with the smallest lng, and lat is the smallest point.

Optionally, the point2 with the lowest lng in the bottom left corner needs to satisfy the point with the lowest lng in the 1/5 area below the screen, i.e. all the points of lat < minLat + (0.2 latDiff);

wherein the first virtual point vpoint 1: lat- (latDiff 0.2); ng is long;

second virtual point vpoint2, lat ═ lat; ng- (lngDiff 0.2);

2) the bottom right-most corner point (point 3 where lat is the smallest and point4 where lng is the largest, both of which may be the same);

the point3 (the third target point) with the lowest lat in the bottom right corner is the point with the lowest lat and the largest lng; the point4 (fourth target point) where the lng is largest at the bottom right corner is the point where lat is smallest among the points where lng is largest.

The point4 at which the lowest right corner lng is the largest needs to satisfy the region 1/5 below the screen, namely the point at which lng is the largest among all the points of lat < minLat + (0.2 latDiff);

wherein the third virtual point vpoint 3: lat- (latDiff 0.2); ng is long;

fourth virtual point vpoint4, lat ═ lat; lng ═ lng + (lngDiff 0.2);

3) the marker point (the marker point where lat is the largest) point5 (the fifth target point) at the uppermost position;

fifth virtual point vpoint 5: lat + (latDiff 0.2); ng is long;

please refer to fig. 6, which illustrates a schematic diagram of pole positions according to an embodiment of the present application; the positions of the points 1-5 (the first target point 61, the second target point 62, the third target point 63, the fourth target point 64, and the fifth target point 65) are shown in fig. 6, wherein the positions of the first target point 61 and the third target point 63 are coincident.

Step 407, displaying the electronic map including the marker line of the target path in the map interface based on the coordinates of the N virtual points; the N virtual points are located within a viewable area of the map interface.

In this embodiment of the present application, the electronic map application may use the coordinates of the N virtual points as an entry reference, and call a mapcontext. Taking the above fig. 6 as an example, please refer to fig. 7, which shows a schematic diagram of a virtual point location according to an embodiment of the present application. As shown in fig. 7, a map interface displayed based on the coordinates of the 5 virtual points vpoint 1-vpoint 5 (the first virtual point 71, the second virtual point 72, the third virtual point 73, the fourth virtual point 74, and the fifth virtual point 75) may be as shown in fig. 7, where the first virtual point 71 and the third virtual point 73 coincide in position.

displaying the electronic map containing the marking line of the target path in the map interface based on the coordinates of the N target points;

In this embodiment of the application, the electronic map application may first display the target path based on the N target points, so as to ensure that the display scale of the target path is sufficiently large. The subsequent user can trigger the electronic map application program to reduce the display scale of the electronic map through a specified operation (for example, when a marked line or a marked point of a determined partial path is blocked).
