Description

Technical Field

[0001] The present application relates to the field of route rendering technology, and in particular to a real-time route location rendering optimization method, apparatus, device and storage medium. Background Art

[0002] Currently, in the autonomous driving cloud control and dispatching platform, it is often necessary to draw real-time vehicle routes based on the vehicle's real-time location reporting points.

[0003] However, due to the frequency of vehicle real-time position reporting points and the possibility of vehicle position fluctuation or position drift, the actual real-time vehicle route drawing often deviates from the route.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing method for drawing a real-time vehicle route has the defect of deviating from the actual route. Summary of the Invention

[0005] In order to make the real-time route drawing of a vehicle more consistent with the actual route, the present application provides a real-time route position rendering optimization method, device, equipment and storage medium.

[0006] In a first aspect, the present application provides a real-time route position rendering optimization method, which has the characteristic of making the real-time route drawing of the vehicle more consistent with the actual route.

[0007] This application is achieved through the following technical solutions:

[0008] A real-time route location rendering optimization method comprises the following steps:

[0009] In a preset route of a target object including a plurality of task coordinates, obtaining the position coordinates of the target object corresponding to the task coordinates at least three times in sequence as the current cursor position;

[0010] After obtaining the current cursor position each time, respectively calculating the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate;

[0011] Based on the calculated straight-line distance, the task coordinate corresponding to the shortest straight-line distance is selected as the current cursor position and updated;

[0012] Based on the updated current cursor position, the route position is rendered using the line drawing method to obtain the current route map;

[0013] Repeat the above steps until the drawn route map includes the end point of the preset route.

[0014] By adopting the above technical solution, in a preset route consisting of several task coordinates of a target object, the cloud control platform sequentially obtains the position coordinates of the target object corresponding to the task coordinates from the vehicle side as the current cursor position, and calculates the straight-line distance between the current cursor position and the corresponding task coordinates and the next task coordinates. Since the shorter the straight-line distance, the more accurate the coordinate position, the task coordinate corresponding to the shortest straight-line distance is selected based on the calculated straight-line distance as the current cursor position and updated to achieve the purpose of real-time route position rendering; at the same time, the position coordinates of the target object are obtained at least 3 times, and the current cursor position is calculated after each acquisition. The straight-line distance between the task coordinates corresponding to the set distance and the next task coordinates is calculated. Based on the calculated straight-line distance, the task coordinates corresponding to the shortest straight-line distance are finally selected from all the calculated straight-line distances as the current cursor position and updated to solve the problem of local fluctuation or position drift of the position data, reducing the large deviation in the rendering route caused by abnormal data and affecting the final route rendering, so that the real-time route drawing of the vehicle is more consistent with the actual route; based on the updated current cursor position, the route position is rendered using the line drawing method to obtain the current route map, and the above steps are repeated until the drawn route map contains the end point of the preset route, that is, the route drawing is completed.

[0015] In a preferred example, the present application may be further configured as follows: before the step of sequentially acquiring the position coordinates of the target object corresponding to the task coordinates at least three times along a route connected by a plurality of task coordinates of the preset target object, the following steps may be further included:

[0016] Based on a preset route consisting of several task coordinates of a target object, the position coordinates of the target object corresponding to the task coordinates are obtained for the first time as the current cursor position;

[0017] First, determine whether the current cursor position is a normal position coordinate;

[0018] When the current cursor position is an abnormal position coordinate, the position coordinate of the target object is acquired at least three times.

[0019] By adopting the above technical solution, based on a preset target object's route consisting of several task coordinates, after obtaining the position coordinates of the target object corresponding to the task coordinates for the first time, it is first determined whether the current cursor position is a normal position coordinate to determine whether the position data has local fluctuations or position drift problems; if the current cursor position is an abnormal position coordinate, the position coordinates of the target object are obtained at least three times to solve the problem of local fluctuations or position drift in the position data, reducing the large deviation in the drawing and rendering route caused by abnormal data and affecting the final route rendering and drawing, and the drawing accuracy is higher, so that the real-time route drawing of the vehicle is more consistent with the actual route; at the same time, the position coordinates of the target object are only obtained at least three times when the current cursor position is an abnormal position coordinate, that is, only once when the current cursor position is a normal position coordinate, which greatly improves the data processing efficiency during real-time route position rendering optimization.

[0020] In a preferred example, the present application can be further configured to include the following steps:

[0021] When the current cursor position is a normal position coordinate, the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate is calculated and compared respectively;

[0022] When the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, the corresponding task coordinate is used as the current cursor position.

[0023] By adopting the above technical solution, if the current cursor position is the normal position coordinate, the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate is calculated and compared respectively; because the shorter the straight-line distance, the more accurate the coordinate position, so when the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, the corresponding task coordinate is used as the current cursor position and updated to achieve the purpose of real-time route position rendering.

[0024] In a preferred example, the present application can be further configured to include the following steps:

[0025] When the straight-line distance between the current cursor position and the corresponding task coordinate is greater than the straight-line distance between the current cursor position and the next task coordinate, the next task coordinate is used as the current cursor position.

[0026] By adopting the above technical solution, if the straight-line distance between the current cursor position and the corresponding task coordinate is greater than the straight-line distance between the current cursor position and the next task coordinate, the next task coordinate is used as the current cursor position, and the more accurate the determined coordinate position is, the more consistent the real-time route drawing of the vehicle is with the actual route.

[0027] In a preferred example, the present application can be further configured to include the following steps:

[0028] When the current cursor position is a normal position coordinate and the last acquired position coordinate of the target object corresponding to the task coordinate is an abnormal position coordinate, respectively calculating and comparing the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate;

[0029] When the straight-line distance between the current cursor position and the corresponding task coordinates is less than the straight-line distance between the current cursor position and the next task coordinates, the route information is not updated.

[0030] By adopting the above technical solution, if the current cursor position is a normal position coordinate and the position coordinate of the target object corresponding to the task coordinate obtained last time is an abnormal position coordinate, at the same time, the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, that is, the accuracy of the current cursor position is more accurate, and the route information is not updated at this time.

[0031] In a preferred example, the present application can be further configured to include the following steps:

[0032] When the current cursor position is a normal position coordinate and the position coordinate of the target object corresponding to the task coordinate obtained last time is a normal position coordinate, respectively calculating the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate and comparing them;

[0033] When the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, the corresponding task coordinate is used as the current cursor position.

[0034] By adopting the above technical solution, if the current cursor position is the normal position coordinate and the position coordinate of the target object corresponding to the task coordinate obtained last time is the normal position coordinate, at the same time, the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, then the corresponding task coordinate is used as the current cursor position, and the route information is updated to achieve the purpose of real-time route position rendering.

[0035] In a preferred example, the present application may be further configured as follows: in a route of a preset target object consisting of a plurality of task coordinates, the task coordinates are distributed in a point group.

[0036] By adopting the above technical solution, the task coordinates are distributed in a point group, that is, any task coordinate is a point set, so that the distribution between adjacent task coordinates is denser, the position coordinate accuracy is higher, and the real-time vehicle route drawing is more consistent with the actual route.

[0037] In a preferred example, the present application can be further configured as follows: the route consisting of a plurality of task coordinates of the preset target object is a task route map indicated by the user on the map board that the vehicle needs to travel.

[0038] By adopting the above technical solution, the user indicates the task route map that the vehicle needs to travel on the map drawing board, that is, a route consisting of several task coordinates of the preset target object is formed, which is flexible to set up.

[0039] In a preferred example, the present application can be further configured to: visualize the roadmap.

[0040] By adopting the above technical solution, the route map is visualized on the cloud control platform, so that the real-time route to be rendered can be fed back and presented on the cloud control platform, which is intuitive and convenient for management personnel to monitor.

[0041] On the second aspect, the present application provides a real-time route position rendering optimization method, which has the characteristic of making the real-time route drawing of the vehicle more consistent with the actual route.

[0042] This application is achieved through the following technical solutions:

[0046] Based on the calculated straight-line distance, the task coordinate corresponding to the shortest straight-line distance is selected as the current cursor position and updated;

[0047] Repeat the above steps until all the location data for drawing the route map are obtained;

[0048] The obtained location data is uploaded to the cloud control platform and a route map is drawn and rendered.

[0049] By adopting the above technical solution, all the location data obtained and processed on the vehicle side for drawing the route map is uploaded to the cloud control platform, and then the cloud control platform draws and renders the route map based on the obtained location data to present it to customers for viewing. In practice, this solution has better performance when executed on the vehicle side.

[0050] On the third aspect, the present application provides a real-time route position rendering optimization method, which has the characteristic of making the real-time route drawing of the vehicle more consistent with the actual route.

[0051] This application is achieved through the following technical solutions:

[0052] A real-time route location rendering optimization method comprises the following steps:

[0053] In a preset route of a target object including several task coordinates, the control vehicle obtains the position coordinates of the target object corresponding to the task coordinates at least three times in sequence;

[0054] The obtained position coordinates corresponding to the task coordinates are uploaded to the cloud control platform and used as the current cursor position;

[0055] In a preset route of a target object consisting of several task coordinates, the cloud control platform calculates the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate each time after obtaining the current cursor position;

[0056] The cloud control platform selects the task coordinates corresponding to the shortest straight-line distance based on the calculated straight-line distance as the current cursor position and updates it;

[0057] The cloud control platform uses the line drawing method to render the route position based on the updated current cursor position to obtain the current route map;

[0058] The cloud control platform repeats the above steps until the drawn route map includes the end point of the preset route.

[0059] In a fourth aspect, the present application provides a real-time route position rendering optimization device, which has the characteristic of making the real-time route drawing of the vehicle more consistent with the actual route.

[0060] This application is achieved through the following technical solutions:

[0063] The cloud control platform is used to preset a route consisting of several task coordinates of the target object and receive the location coordinates reported by the vehicle-mounted module.

[0064] By adopting the above technical solution, the on-board module obtains the position coordinates of the target object and reports them to provide real-time position coordinate information for the real-time route drawing of the target object; the cloud control platform executes the above-mentioned real-time route position rendering optimization method based on the preset route of the target object consisting of several task coordinates and the position coordinates reported by the received on-board module to solve the problem of local fluctuation or position drift of position data, reduce the large deviation in the rendering route caused by abnormal data and affect the final route rendering, so that the real-time route drawing of the vehicle is more consistent with the actual route.

[0065] In a fifth aspect, the present application provides a device having the characteristic of making the real-time route drawing of a vehicle more consistent with the actual route.

[0067] A device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned real-time route location rendering optimization method are implemented.

[0068] In a sixth aspect, the present application provides a storage medium having the characteristic of making the real-time route drawing of the vehicle more consistent with the actual route.

[0069] This application is achieved through the following technical solutions:

[0070] A storage medium stores a computer program, which, when executed by a processor, implements the steps of the above-mentioned real-time route position rendering optimization method.

[0071] In summary, this application includes at least one of the following beneficial technical effects:

[0072] 1. In a preset route consisting of several task coordinates of a target object, the cloud control platform sequentially obtains the position coordinates of the target object corresponding to the task coordinates from the vehicle side as the current cursor position, and calculates the straight-line distance between the current cursor position and the corresponding task coordinates and the next task coordinates. Since the shorter the straight-line distance, the more accurate the coordinate position, the task coordinate corresponding to the shortest straight-line distance is selected based on the calculated straight-line distance as the current cursor position and updated to achieve the purpose of real-time route position rendering; at the same time, the position coordinates of the target object are obtained at least 3 times, and finally, among all the calculated straight-line distances, the task coordinate corresponding to the shortest straight-line distance is selected as the current cursor position and updated to solve the problem of local fluctuation or position drift of the position data, reducing the large deviation in the rendering route caused by abnormal data and affecting the final route rendering, so that the real-time vehicle route rendering is more consistent with the actual route;

[0073] 2. If the current cursor position is abnormal, the target object's position coordinates are acquired at least three times to address local fluctuations or drift in position data. This reduces the impact of large deviations in route rendering caused by abnormal data, which can affect the final route rendering. This results in higher rendering accuracy, making the vehicle's real-time route rendering more consistent with the actual route. Furthermore, the target object's position coordinates are acquired at least three times only when the current cursor position is abnormal, compared to only once when the current cursor position is normal. This significantly improves data processing efficiency during real-time route position rendering optimization.

[0074] 3. If the current cursor position is the normal position coordinate, calculate the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate and compare them. Since the shorter the straight-line distance, the more accurate the coordinate position, if the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, use the corresponding task coordinate as the current cursor position and update it. If the straight-line distance between the current cursor position and the corresponding task coordinate is greater than the straight-line distance between the current cursor position and the next task coordinate, use the next task coordinate as the current cursor position. This achieves the purpose of real-time route position rendering.

[0075] 4. If the current cursor position is a normal position coordinate and the position coordinates of the target object corresponding to the task coordinates obtained last time are abnormal position coordinates, and the straight-line distance between the current cursor position and the corresponding task coordinates is less than the straight-line distance between the current cursor position and the next task coordinates, that is, the accuracy of the current cursor position is relatively accurate, the route information will not be updated at this time; if the current cursor position is a normal position coordinate and the position coordinates of the target object corresponding to the task coordinates obtained last time are normal position coordinates, the corresponding task coordinates will be used as the current cursor position, and the route information will be updated to achieve the purpose of real-time route position rendering;

[0076] 5. The task coordinates are distributed in a point cluster, that is, any task coordinate is a point set. The denser the distribution between adjacent task coordinates, the higher the accuracy of the position coordinates, and the more consistent the real-time route drawing of the vehicle is with the actual route;

[0077] 6. All the location data obtained and processed by this solution on the vehicle side for drawing the route map is uploaded to the cloud control platform, and then the cloud control platform draws and renders the route map based on the obtained location data to present it to the customer. In practice, this solution has better performance when executed on the vehicle side. BRIEF DESCRIPTION OF THE DRAWINGS

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0088] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0089] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0090] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0091] Reference Figure 1 , an embodiment of the present application provides a real-time route location rendering optimization method, and the main steps of the method are described as follows.

[0092] S01: In a preset route of a target object including several task coordinates, the position coordinates of the target object corresponding to the task coordinates are obtained at least three times in sequence as the current cursor position;

[0093] S011: After obtaining the current cursor position each time, calculate the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate;

[0094] S012: Based on the calculated straight-line distance, select the task coordinate corresponding to the shortest straight-line distance as the current cursor position and update it;

[0095] S3: Based on the updated current cursor position, the route position is rendered using a line drawing method to obtain the current route map;

[0096] S4: Repeat the above steps until the drawn route map includes the end point of the preset route.

[0097] Furthermore, before the step of S01: obtaining the position coordinates of the target object corresponding to the task coordinates at least three times in a preset route including a plurality of task coordinates of the target object, the method further includes the following steps:

[0098] S1: Based on a preset route consisting of several task coordinates of a target object, first obtain the position coordinates of the target object corresponding to the task coordinates as the current cursor position;

[0099] S2: Determine whether the current cursor position is the normal position coordinate;

[0100] If the current cursor position is an abnormal position coordinate, the position coordinate of the target object is obtained at least three times in sequence.

[0101] Reference Figure 2 , further, S02: if the current cursor position is the normal position coordinate, then respectively calculate the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate and compare them;

[0102] S021: Determine whether the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate;

[0103] S022: If the straight-line distance between the current cursor position and the corresponding task coordinate is less than the straight-line distance between the current cursor position and the next task coordinate, the corresponding task coordinate is used as the current cursor position.

[0104] S023: If the straight-line distance between the current cursor position and the corresponding task coordinate is greater than the straight-line distance between the current cursor position and the next task coordinate, the next task coordinate is used as the current cursor position.

[0105] Further, S022: If the straight-line distance between the current cursor position and the corresponding task coordinates is less than the straight-line distance between the current cursor position and the next task coordinates, before taking the corresponding task coordinates as the current cursor position, first determine whether the position coordinates of the target object corresponding to the task coordinates obtained last time are abnormal position coordinates; if the position coordinates of the target object corresponding to the task coordinates obtained last time are abnormal position coordinates, the route information will not be updated.

[0106] If the position coordinates of the target object obtained last time that correspond to the task coordinates are normal position coordinates, the corresponding task coordinates are used as the current cursor position, and the route information is updated.

[0107] Specifically, within a pre-defined target object's route, which consists of several connected task coordinates, the task coordinates are distributed as a point cloud. If more than one task coordinate is obtained, it forms a point cloud cluster, meaning any task coordinate is a collection of points. This allows for a denser distribution of adjacent task coordinates, resulting in higher positional accuracy and a more accurate real-time route mapping for the vehicle.

[0108] In this embodiment, the acquired point cloud is pre-processed using an existing point cloud processing method so that the point set of the task coordinates is abstracted into a point coordinate, which will not be described in detail here.

[0109] Reference Figure 3 , several ideal coordinates are preset, including the starting point task coordinates, point A task coordinates, point B task coordinates, point C task coordinates, point D task coordinates, point E task coordinates, point F task coordinates and end point task coordinates, and several task coordinates are connected in sequence to form a route for the target object.

[0110] Based on the preset route containing the target object, the position coordinates of the target object corresponding to the task coordinates are obtained in sequence, such as obtaining the position coordinates of point P1 corresponding to the starting task coordinates as the current cursor position, and determining whether the current cursor position is the normal position coordinate.

[0111] Since the position coordinates of point P1 are judged to be normal position coordinates, the straight-line distances between the position coordinates of point P1 and the starting task coordinates and the task coordinates of point A are calculated and compared.

[0112] If the straight-line distance between the position coordinates of point P1 and the starting task coordinates is greater than the straight-line distance between the position coordinates of point P1 and the task coordinates of point A, the task coordinates of point A are used as the current cursor position, and a route is drawn from the starting task coordinates to the task coordinates of point A.

[0113] Next, refer to Figure 4 , obtain the position coordinates of the target object corresponding to the second task coordinates, such as, obtain the position coordinates of point P2 corresponding to the task coordinates of point A as the current cursor position, and determine whether the current cursor position is the normal position coordinates.

[0114] Since the position coordinates of point P2 are judged to be normal position coordinates, the straight-line distances between the position coordinates of point P2 and the task coordinates of point A and point B are calculated and compared.

[0115] If the straight-line distance between the position coordinates of point P2 and the task coordinates of point A is greater than the straight-line distance between the position coordinates of point P2 and the task coordinates of point B, the task coordinates of point B are used as the current cursor position, and the route from the task coordinates of point A to the task coordinates of point B is continued to be drawn.

[0116] Next, refer to Figure 5 , obtain the position coordinates of the target object corresponding to the third task coordinates, such as, obtain the position coordinates of point P3 corresponding to the task coordinates of point B as the current cursor position, and determine whether the current cursor position is the normal position coordinates.

[0117] Because the position coordinates of point P3 are determined to be abnormal, i.e., the position coordinates of point P3 have experienced a transient reported offset, exhibiting certain position fluctuations or drift, the position coordinates of point P3 are acquired at least three times in sequence to address the issue of local fluctuations or drift in the position data and reduce the impact of large deviations in the rendering route caused by abnormal data, which could affect the final route rendering. In this embodiment, when local fluctuations or drift in the position data occur, the position coordinate data is acquired three times in sequence.

[0118] After obtaining the position coordinates of point P3, use the position coordinates of point P3 as the current cursor position, calculate the straight-line distances between the current cursor position and the task coordinates of point B and point C, and record them.

[0119] Next, refer to Figure 6 , obtain the position coordinates of point P3 corresponding to the task coordinates of point C in turn as the current cursor position, calculate the straight-line distance between the current cursor position and the task coordinates of point C and point D again, and record them.

[0120] Secondly, refer to Figure 7 , obtain the position coordinates of point P3 corresponding to the task coordinates of point D in turn as the current cursor position, calculate the straight-line distance between the current cursor position and the task coordinates of point D and point E again, and record them.

[0121] Finally, based on the calculated straight-line distance, the task coordinates corresponding to the shortest straight-line distance are selected as the current cursor position and updated.

[0122] Reference Figure 5-Figure 7 In this embodiment, taking the position coordinates of point P3 as an example, the calculated straight-line distances include the straight-line distances between the first point P3 position coordinate and the task coordinates of point B, the straight-line distance between the first point P3 position coordinate and the task coordinates of point C, the straight-line distance between the second point P3 position coordinate and the task coordinates of point C, the straight-line distance between the second point P3 position coordinate and the task coordinates of point D, the straight-line distance between the third point P3 position coordinate and the task coordinates of point D, and the straight-line distance between the third point P3 position coordinate and the task coordinates of point E. After comparison, the shortest straight-line distance, i.e., the straight-line distance between the third point P3 position coordinate and the task coordinates of point E, is selected. The task coordinates of point E are used as the current cursor position of the point P3 position coordinates. Even if the point P3 position coordinates are updated to the task coordinates of point E, the drawn traveled route information is updated from the task coordinates of point B to the task coordinates of point E.

[0123] Reference Figure 8 , obtain the position coordinates of the target object corresponding to the sixth task coordinates, such as, obtain the position coordinates of point P4 corresponding to the task coordinates of point E as the current cursor position, and determine whether the current cursor position is a normal position coordinate.

[0124] Since the position coordinates of point P4 are judged to be normal, that is, the position coordinates of point P4 are restored to normal, the judgment is made again based on the current cursor position, and the straight-line distances between the position coordinates of point P4 and the task coordinates of point E and point F are calculated and compared.

[0125] When the calculated straight-line distance between the P4 point position coordinate and the E point task coordinate is less than the straight-line distance between the P4 point position coordinate and the F point task coordinate, and the last acquired P3 point position coordinate corresponding to the task coordinate of the target object is an abnormal position coordinate, the E point task coordinate is used as the current cursor position, and the route information is not updated at this time.

[0126] Based on the updated current cursor position, a line drawing method is used to render the route position, resulting in the current route map. The above steps are repeated until the drawn route map includes the destination of the preset route. In this embodiment, the line drawing method can be a polyline() function or a line() function, so that the current cursor position of the current update is sequentially connected to the current cursor position of the next update, ultimately forming a route map including the destination.

[0127] The route map can be displayed visually, and the rendered real-time route can be fed back and presented on the cloud control platform, which is intuitive and convenient for management personnel to monitor.

[0128] Furthermore, the preset target object's route consisting of several task coordinates is a task route map indicated by the user on the map board that the vehicle needs to travel through, and the setting is flexible.

[0129] Furthermore, a real-time route position rendering optimization method is provided, which is based on a preset target object's route consisting of several task coordinates. The position coordinates of the target object corresponding to the task coordinates are first obtained as the current cursor position, and then it is determined whether the current cursor position is a normal position coordinate.

[0130] If not, the position coordinates of the target object corresponding to the task coordinates are obtained at least three times in sequence as the current cursor position, and after each acquisition of the position coordinates, the straight-line distance between the current cursor position and the corresponding task coordinates and the next task coordinates is calculated.

[0131] Because the shorter the straight-line distance, the more accurate the coordinate position, the task coordinate corresponding to the shortest straight-line distance among all the calculated straight-line distances is selected as the current cursor position and updated to solve the problem of local fluctuation or position drift of position data. This reduces the large deviation in the rendering route caused by abnormal data, which affects the final route rendering and makes the real-time vehicle route drawing more consistent with the actual route. At the same time, the position coordinates of the target object are only acquired at least three times when the current cursor position is an abnormal position coordinate, that is, only once when the current cursor position is a normal position coordinate, which greatly improves the data processing efficiency during real-time route position rendering optimization.

[0132] If the current cursor position is a normal position coordinate, the straight-line distance between the current cursor position and the corresponding task coordinate and the next task coordinate is calculated and compared.

[0133] Since the shorter the straight-line distance, the more accurate the coordinate position, when the straight-line distance between the current cursor position and the corresponding task coordinates is less than the straight-line distance between the current cursor position and the next task coordinates, and the position coordinates of the target object corresponding to the task coordinates obtained last time are abnormal position coordinates, that is, the accuracy of the current cursor position is relatively accurate, the route information will not be updated at this time.

[0134] When the straight-line distance between the current cursor position and the corresponding task coordinates is less than the straight-line distance between the current cursor position and the next task coordinates, and the position coordinates of the target object corresponding to the task coordinates obtained last time are normal position coordinates, the corresponding task coordinates are used as the current cursor position.

[0135] If the current cursor position is the normal position coordinate and the straight-line distance between the current cursor position and the corresponding task coordinate is greater than the straight-line distance between the current cursor position and the next task coordinate, then the next task coordinate is used as the current cursor position, and the route information is updated to achieve the purpose of real-time route position rendering.
