The background management server may analyze and perform other processing on the received data such as the user request, and feed back a processing result (e.g., a webpage, information, or data obtained or generated according to the user request) to the client. In addition, the server 105 may also be a cloud server, i.e., the server 105 has a cloud computing function.
It should be noted that the map data processing method provided by the embodiment of the present disclosure may be executed by the server 105. Accordingly, the map data processing apparatus provided by the embodiment of the present disclosure may be provided in the server 105.

In the technical scheme of the disclosure, before the personal information of the user is acquired or collected, the authorization or the consent of the user is acquired.
The embodiment of the present disclosure provides a map data processing method, and a map data processing method according to an exemplary embodiment of the present disclosure is described below with reference to fig. 2 to 5B in conjunction with the system architecture of fig. 1. The map data processing method of the embodiment of the present disclosure may be executed by the server 105 shown in fig. 1, for example.
Fig. 2 schematically shows a flowchart of a map data processing method according to an embodiment of the present disclosure.
As shown in fig. 2, the map data processing method 200 of the embodiment of the present disclosure may include, for example, operations S210 to S230.
In operation S210, an occlusion reference value between the base map element and the upper marker element is determined according to the base map element coordinates and the upper marker element coordinates in the map data.
The map-base elements include elements determined using map-base data, such as navigation car logos, speed limit signs, and the like. The upper layer indicating elements include elements for providing interactive operation for the user, prompting elements and the like, for example, the content of the upper layer indicating elements may include the predicted time and the predicted distance of the current navigation route and the like.
The occlusion reference value may be understood as a reference value for determining whether or not there is an occlusion between the base map element and the upper layer indicating element.
It should be noted that, in the embodiment of the present disclosure, in the case of a two-dimensional reference coordinate system, the plane where the bottom drawing element is located coincides with the plane where the upper layer marking element is located, and the coinciding plane is, for example, the plane Pc. Taking a two-dimensional reference coordinate system including an X coordinate axis and a Y coordinate axis as an example, the embodiment of the present disclosure only considers a case where the size of the X coordinate axis and the size of the Y coordinate axis of the bottom map element and the upper layer marking element on the plane Pc are not 0. For example, when the base map element is a line, the case where the size of the X coordinate axis or the size of the Y coordinate axis of the base map element is 0 in the mathematical sense is not considered. In the embodiment of the present disclosure, when the bottom map element and the upper layer indicating element are blocked, it indicates that the bottom map element and the upper layer indicating element are overlapped based on the X coordinate axis and the Y coordinate axis of the two-dimensional reference coordinate system. In the case of a three-dimensional reference coordinate system, the plane of the underlying map element is parallel to or coincident with the plane of the overlying marking element. Taking the three-dimensional reference coordinate system including an X coordinate axis, a Y coordinate axis and a Z coordinate axis, and both the plane of the bottom map element and the plane of the upper-layer marking element are XY planes, in the embodiment of the present disclosure, the dimension of the upper-layer marking element based on the Z coordinate axis is set to be 0 by default, and the dimension of the bottom map data based on the Z coordinate axis may not be 0. The following description is made by taking the above two reference coordinate systems as examples.
Taking a two-dimensional reference coordinate system as an example, the overlapping length between the base map element and the upper layer marking element based on each coordinate axis may be used as an occlusion reference value, or the overlapping area between the base map element and the upper layer marking element based on the two-dimensional reference coordinate system may be used as an occlusion reference value.
Taking a three-dimensional reference coordinate system as an example, the overlapping length of each coordinate axis based on the XY plane between the base map element and the upper-layer indicating element may be used as an occlusion reference value, or the overlapping area based on the XY plane between the map element and the upper-layer indicating element may be used as an occlusion reference value.
In operation S220, an occlusion confirmation result is determined according to the occlusion reference value.
Occlusion confirmation results may include the presence and absence of occlusions.
In operation S230, in case that the occlusion confirmation result is that there is an occlusion, at least one of the position of the base map and the coordinates of the upper indicating element is adjusted.
Under the condition that the shielding confirmation result is that shielding exists, the position of the upper layer marking element which shields the base map element can be shifted by adjusting the relative position between the base map element and the upper layer marking element, so that the problem that shielding exists between the upper layer marking element and the base map element is solved. The adjusting at least one of the bottom map position and the upper layer indicating element coordinate in operation S230 includes adjusting both the bottom map position and the upper layer indicating element coordinate at the same time, and at this time, the relative positions of the bottom map position and the upper layer indicating element coordinate may be changed according to adjusting the bottom map position and the upper layer indicating element coordinate with different adjustment values, respectively.
It should be noted that the positions of the map elements are related to map data, and the map data may include building data, road data, and the like with respect to position determination. Merely adjusting the coordinates of the map elements changes the relative positions between different map data, resulting in distortion of the map data. Therefore, the map data processing method according to the embodiment of the present disclosure can maintain the relative position between different base map data unchanged by adjusting the base map position, and adjust the relative positions of the upper layer marking element and the base layer element, thereby solving the problem of the existence of shielding between the upper layer marking element and the base map element.
It should be further noted that, in the case that the occlusion confirmation result indicates that there is an occlusion, at least one of the position of the base map and the coordinates of the upper-layer marking element may be adjusted until the occlusion confirmation result indicates that there is no occlusion.
According to the map data processing method, the positions of the base map elements and the positions of the upper layer marking elements can be reflected by the base map element coordinates and the upper layer marking element coordinates, so that the shielding reference value between the base map elements and the upper layer marking elements can be accurately determined, the shielding confirmation result is automatically determined according to the shielding reference value, at least one of the base map positions and the upper layer marking element coordinates can be automatically adjusted when the shielding confirmation result indicates that shielding exists, automatic adaptation of the base map element positions and the upper layer marking element positions is achieved, and the problem that shielding exists between the upper layer marking elements and the base map elements is solved. Especially, under the application scene of multiple screens, the positions of the elements of the base map and the positions of the marking elements on the upper layer can be automatically adapted for each screen, so that the method is more efficient.
Fig. 3 schematically illustrates a map data determination method 300 according to another embodiment of the present disclosure.
As shown in fig. 3, the map data determination method 300 according to an embodiment of the present disclosure includes operations S340 to S360.
In operation S340, in a case that there is no occlusion in the occlusion confirmation result, an adjustment reference value between the base map element and the upper indicating element is determined according to the base map element coordinate and the upper indicating element coordinate in the map data.
There are the following situations: although the bottom map element and the upper layer marking element are not shielded, the bottom map element and the upper layer marking element are close to each other, which causes problems such as difficulty in visually distinguishing the bottom map element from the upper layer marking element.
The adjustment reference value can be understood as a reference value for determining whether the base map element and the upper layer indicating element need to be adjusted in the case where there is no occlusion.
In operation S350, an adjustment result is determined according to the adjustment reference value and the adjustment threshold.
Illustratively, the adjustment threshold may be configurable.
In operation S360, in case that the adjustment result is that the adjustment is required, at least one of the position of the base map and the coordinates of the upper indicating element is adjusted.
It should be noted that, in the case that the adjustment result is that adjustment is required, at least one of the position of the base map and the coordinates of the upper-layer marking element may be adjusted until the adjustment result is that adjustment is not required.
According to the map data processing method provided by the embodiment of the disclosure, whether at least one of the position of the base map and the coordinates of the upper-layer marking elements is adjusted or not can be determined according to the adjustment reference value and the adjustment threshold value under the condition that shielding does not exist, so that the requirements of clear layout, high observability and the like between the upper-layer marking elements and the base map elements are met, and the user experience is improved.
Illustratively, as shown in fig. 3, the map data determining method 300 according to an embodiment of the present disclosure may further include operations S310 to S330.
In operation S310, an occlusion reference value between the base map element and the upper marker element is determined according to the base map element coordinates 301 and the upper marker element coordinates 302 in the map data.
In operation S320, an occlusion confirmation result is determined according to the occlusion reference value.
For example, as shown in fig. 3, an occlusion confirmation result may be determined according to a comparison result of the occlusion reference value and the occlusion threshold value.
For example, in the example of fig. 3, when the overlap length between the base map element and the upper-level indicating element based on each coordinate axis is used as the occlusion reference value, when the occlusion reference value is greater than 0, it indicates that there is an occlusion between the base map element and the upper-level indicating element, and at this time, the occlusion threshold value may be 0.
In operation S330, in case that the occlusion confirmation result is that there is an occlusion, at least one of the map position and the upper marker element coordinates is adjusted.
According to the map data processing method of the embodiment of the disclosure, the upper-layer marking element coordinate, the bottom map element coordinate and the bottom map position are determined based on the reference coordinate system, and adjusting the upper-layer marking element coordinate may include: and adjusting the coordinate of the upper layer marking element based on at least one coordinate axis of a reference coordinate system, wherein the reference coordinate system is a two-dimensional reference coordinate system or a three-dimensional reference coordinate system.
When the reference coordinate system is a two-dimensional reference coordinate system, adjusting the coordinate of the upper-layer marking element based on at least one coordinate axis of the reference coordinate system is equivalent to adjusting the relative position between the upper-layer marking element and the bottom map element.
Taking a three-dimensional reference coordinate system including an X coordinate axis, a Y coordinate axis, and a Z coordinate axis as an example, for example, a plane where the upper layer indicating element is located is parallel to the XY plane, and adjusting coordinates of the upper layer indicating element based on at least one of the X coordinate axis and the Y coordinate axis is equivalent to the case where the reference coordinate system is a two-dimensional reference coordinate system. Namely, the relative position between the upper layer marking element and the bottom picture element is adjusted. In the three-dimensional reference coordinate system, adjusting the coordinate of the upper-layer marking element based on the Z axis is equivalent to adjusting the size ratio between the upper-layer marking element and the bottom map element. It can be understood that when there is a block between the upper layer marking element and the bottom map element, if the size ratio between the upper layer marking element and the bottom map element is reduced, the area of the upper layer marking element blocking the bottom map element is smaller. Therefore, the problem that shielding exists between the upper layer marking element and the bottom map element can be solved.
For example, when the reference coordinate system is a two-dimensional reference coordinate system, the two-dimensional reference coordinate system may be a screen coordinate system. The screen coordinate system may be understood as a two-dimensional coordinate system in units of pixels.
According to the map data determining method provided by the embodiment of the disclosure, the relative positions of the upper layer mark element and the bottom map element can be adjusted in multiple ways, so that the problem of shielding between the upper layer mark element and the bottom map element is solved.
FIG. 4A schematically illustrates a schematic diagram of determining an occlusion reference value according to an embodiment of the present disclosure.
As shown in fig. 4A, the determining of the occlusion reference value between the base map element and the upper marker element according to the base map element coordinate and the upper marker element coordinate in the map data in operation S410 may include operations S411 to S412.
In operation S411, a relative position 403 between the bottom map element and the top map element, a two-dimensional size 404 of the bottom map element, and a two-dimensional size 405 of the top map element are determined according to the bottom map element coordinates 401 and the top map element coordinates 402.
It can be understood that, according to the coordinates of the elements of the bottom map and the coordinates of the marking elements of the upper layer, the two-dimensional size of the elements of the bottom map and the two-dimensional size of the marking elements of the upper layer can be determined, and the shape, the size and the like can be determined through the two-dimensional sizes. When determining whether occlusion exists between the bottom map element and the upper layer marking element, the relative position between the bottom map element and the upper layer marking element is also required to be determined.
For example, the two-dimensional size of the base map element may include a value range of the base map element based on each coordinate axis, and the two-dimensional size of the upper indicator element may include a value range of the upper indicator element based on each coordinate axis. At this time, the relative position between the bottom drawing element and the upper layer indicating element has been determined.
In operation S412, an overlap size 406 between the bottom map element and the top map element is determined according to the relative position 403 between the bottom map element and the top map element, the two-dimensional size 404 of the bottom map element, and the two-dimensional size 405 of the top map element, so as to obtain an occlusion reference value.
For example, the occlusion reference value may be an overlap size, and in the above example, the overlap size between the bottom map element and the upper layer indicating element may be an overlap length of the bottom map element and the upper layer indicating element based on the X coordinate axis and the Y coordinate axis, respectively, or an overlap area of the bottom map element and the upper layer indicating element based on the same reference coordinate system.
According to the map data processing method, the shielding reference value between the bottom map element and the upper layer marking element can be accurately determined according to the relative position between the bottom map element and the upper layer marking element, the two-dimensional size of the bottom map element and the two-dimensional size of the upper layer marking element, which are determined by the bottom map element coordinate and the upper layer marking element coordinate.
Fig. 4B schematically shows a schematic diagram of a map data processing method according to an embodiment of the present disclosure.
As shown in FIG. 4B, the upper level labeling element Em1, the bottom map element Eb1, the bottom map element Eb2, and the two-dimensional reference frame are shown. The bottom map element Eb1 is a navigation logo for indicating the current position and direction, and the bottom map element Eb2 is a navigation route. According to the map data processing method of the embodiment of the present disclosure, it may be determined that the occlusion confirmation results of the upper indicator element Eml and the bottom map element Eb1 shown in fig. 4B are that an occlusion exists, and the occlusion confirmation results of the upper indicator element Em1 and the bottom map element Eb2 are that no occlusion exists.
Fig. 5A schematically illustrates a schematic diagram of determining an adjustment reference value according to an embodiment of the present disclosure.
