[0025] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0026] Figure 1 is a schematic diagram according to the first embodiment of the present disclosure.

[0027] It should be noted that the executor of the map surface data processing method of this embodiment is a map surface data processing device, which can be implemented by software and / or hardware. The device can be configured in an electronic device, and the electronic device may include but is not limited to a terminal, a server, etc.

[0028] The embodiments of the present disclosure relate to the field of artificial intelligence technology, and more specifically, to the field of autonomous driving and computer vision technology.

[0029] Among them, Artificial Intelligence (AI) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.

[0030] Autonomous driving refers to the use of radar, laser, ultrasound, Global Position System (GPS), odometer, computer vision and other technologies to perceive its surrounding environment, identify obstacles and various signs through advanced computing and control systems, and plan appropriate paths to control vehicle driving.

[0031] Computer vision is the use of cameras and computers to replace the human eye to identify, track and measure targets, and further perform graphic processing to make the computer processing into an image that is more suitable for human eye observation or transmission to instrument detection.

[0032] like Figure 1 As shown, the map surface data processing method includes:

[0033] S101: receiving map change data.

[0034] Among them, change data refers to data used to change existing map data information in the map. The existing map data information may be, for example, road line data information in the map, data information of road signs in the map, data information of points of interest in the map, etc. The road line data information in the map may be the starting and ending points and the end points of the road line, the main trunk of the road line and other location information, or it may also be the name number of the road line and the length data information of the road line, etc., and there is no limitation on this.

[0035] For example, Figure 2 As shown, Figure 2 is a schematic diagram of road line distribution in an embodiment of the present disclosure, Figure 2 The line segments with serial numbers in the figure represent road lines, and the black endpoints represent the starting and ending endpoints of the road lines.

[0036] For example, when the actual road is extended and modified in the actual scenario, the starting and ending points of the road line corresponding to the actual road in the map will be adjusted accordingly. The data describing the corresponding adjustment changes of the starting and ending points in the map can be change data. The change data can also be used to describe the modification of the spatial position of the road in the map, or it can also describe the modification caused by any other possible modification forms of the road line in the map, without limitation.

[0037] In the disclosed embodiments, when receiving map change data, a data acquisition device may be pre-configured on the map surface data processing device to collect road line data of actual roads in actual scenes, and the collected road line data may be analyzed and processed, and then compared with the original road line data corresponding to the actual roads to obtain the map change data, or a data transmission interface may be pre-configured for the map surface data processing device to receive change data transmitted by other electronic devices via the data transmission interface, and there is no restriction on this.

[0038] S102: Acquire initial surface data of the restricted area in the map.

[0039] The restricted area refers to the area surrounded by boundary road lines in the map. Within this area, the passage of vehicles can be controlled based on certain control conditions.

[0040] Among them, the initial surface data can refer to the surface data related to the restricted surface in the map. The initial surface data can be used to describe the location information related to the restricted surface, as well as the data information related to the road line affected by the restricted surface, etc. The initial surface data can be specific, for example, the road line data affected by the restricted surface, such as the starting and ending points of the road line affected by the restricted surface, the main trunk of the road line and other location information, or it can also be the name and number of the road line affected by the restricted surface and the length data information of the road line, etc., and there is no limitation on this.

[0041] For example, Figure 2 Road line 1, road line 2, road line 3 and road line 4 in the figure are the boundary road lines that constitute the restricted surface. The shaded area surrounded by the four road lines is the restricted surface in the map. The data information of the boundary road lines and other road lines that the restricted surface affects can be used as the initial surface data of the restricted surface.

[0042] In the disclosed embodiment, when obtaining the initial surface data of the restricted surface in the map, the restricted surface number of the restricted surface and the boundary road line number of the restricted surface can be obtained, and then a database table lookup can be performed based on the obtained restricted surface number of the restricted surface and the boundary road line number of the restricted surface, and the road line data of the restricted surface can be obtained from the corresponding database record table as the initial surface data of the restricted surface in the map.

[0043] For example, Figure 3 As shown, Figure 3 It is a schematic diagram of the restricted surface boundary information table in the embodiment of the present disclosure. The restricted surface boundary information table records data information such as the restricted surface number of the restricted surface and the numbers of the boundary road lines that constitute the restricted surface. Based on the restricted surface number of the restricted surface and the numbers of the boundary road lines that constitute the restricted surface, multi-table joint query and other processing can be performed to obtain the initial surface data of the restricted surface.

[0044] S103: Analyze and process the changed data to obtain target surface data of the restricted area.

[0045] Among them, the target surface data refers to the surface data related to the restricted surface obtained after the initial surface data of the restricted surface is changed. The target surface data can be used to describe the position information related to the restricted surface after the change, as well as the data information related to the road line affected by the changed restricted surface, etc. The target surface data can be specifically, for example, the road line related data information obtained after the position information such as the starting and ending points and the main trunk of the road line affected by the restricted surface is corrected, or the length data information of the road line obtained after the change processing, etc., and there is no limitation on this.

[0046] After receiving the map change data, the embodiment of the present disclosure may parse and process the change data to obtain the target surface data of the restricted area.

[0047] In the embodiment of the present disclosure, when the change data is parsed and processed, the road line change information in the received change data can be extracted, and the change information of the road line that affects the restricted surface can be obtained by parsing. The change information can be, for example, the extension and trimming of the road line in an actual scenario, or the adjustment of the position of the road line, and the extracted road line change information can be used as the target surface data of the restricted surface.

[0048] In other embodiments, a manual verification process can be introduced to review the validity of the change data, and then the road line change information in the change data can be extracted to obtain the target surface data of the restricted surface, or any other possible method can be used to parse the change data to obtain the target surface data of the restricted surface.

[0049] In the disclosed embodiment, after the change data is parsed to obtain the target surface data of the restricted surface, the initial surface data of the restricted surface can be updated to the target surface data, as will be described in detail in the subsequent embodiments.

[0050] S104: Update the initial surface data of the restricted area to the target surface data.

[0051] In the embodiment of the present disclosure, after parsing the change data to obtain the target surface data of the restricted area, the initial surface data of the restricted area may be updated to the target surface data.

[0052] In the embodiment of the present disclosure, when the initial surface data of the restricted surface is updated to the target surface data, the initial surface data of the restricted surface stored in the database can be updated. For example, the data records in the table item where the road line affected by the restricted surface is stored in the database can be added, modified or deleted to update the initial surface data of the restricted surface to the target surface data.

[0053] In other embodiments, the task management platform can be used to automatically create a restricted surface protection plan based on the target surface data, and modify the initial surface data based on the target surface data, and store the modified target surface data in the restricted surface data record table in the database, update the initial surface data in the restricted surface database to the target surface data, and perform the modified restricted surface drawing process to reflect the modified restricted surface data in the map.

[0054] In this embodiment, by receiving change data of the map, the initial surface data of the restricted surface in the map is obtained, the change data is parsed and processed to obtain the target surface data of the restricted surface, and the initial surface data of the restricted surface is updated to the target surface data. As a result, the surface data of the restricted surface in the map can be timely corrected and updated in linkage according to the change data of the map, thereby effectively ensuring the accuracy of the surface data of the restricted surface in the map.

[0055] Figure 4 is a schematic diagram according to a second embodiment of the present disclosure.

[0056] like Figure 4 As shown, the map surface data processing method includes:

[0057] S401: Receive map change data.

[0058] The description of S401 can be referred to the above embodiment, and will not be repeated here.

[0059] S402: Acquire initial surface data of the restricted area in the map.

[0060] The initial surface data includes: a restricted area, which refers to a surface area surrounded by road lines as boundaries.

[0061] In the embodiment of the present disclosure, when obtaining the initial surface data of the restricted surface in the map, the restricted surface area in the map can be obtained, and the boundary road line data constituting the restricted surface can be obtained, and the road line data affected by the restricted surface area can be obtained as the initial surface data.

[0062] S403: Analyze the change data to obtain a plurality of road change data corresponding to the plurality of road lines in the map.

[0063] The road lines in the map may include: boundary road lines of the restricted area, other road lines within the restricted area that are not boundary road lines, and road lines outside the restricted area.

[0064] Among them, road change data can be used to describe changes in the spatial position and length data of the road. The road change data can be that the spatial position of the road line has been adjusted, for example, the spatial position of the road line has changed from within the restricted surface to outside the restricted surface, or the spatial position of the road line has changed, that is, the road line that is not affected by the restricted surface enters the restricted surface.

[0065] In the disclosed embodiment, when the change data is parsed to obtain a plurality of road change data corresponding to a plurality of road lines in the map, data extraction can be performed on the received change data to extract the change data of the plurality of road lines, and then the change data is analyzed to obtain spatial position change data or length change data of the road lines as the road change data corresponding to the road lines, and there is no limitation on this.

[0066] S404: Determine a target road line from among a plurality of road lines, wherein the target road line is a road line that has been acted upon by the restricted area, or the target road line is a road line that is newly configured to be acted upon by the restricted area.

[0067] Among them, the multiple road lines are divided into road lines located within the restricted surface, and road lines located outside the restricted surface. The road lines included in the restricted surface can be called road lines that have been affected by the restricted surface area. When the road lines change, the spatial position of the road lines that have been affected by the restricted surface can be changed to outside the restricted surface, or the spatial position of the road lines that have not been affected by the restricted surface can be changed to inside the restricted surface. Among them, the target road line is the road line that has been affected by the restricted surface area, or the target road line is a road line newly configured to be affected by the restricted surface area.

[0068] After parsing the change data to obtain a plurality of road change data corresponding to a plurality of road lines in a map, the embodiment of the present disclosure can determine a target road line from the plurality of road lines.

[0069] In the disclosed embodiment, after determining a target road line from a plurality of road lines, the change data of the road lines involving the restricted area can be searched in the change data, and the road line to which the change data belongs can be used as the target road line.

[0070] In some other embodiments, it is also possible to search through the items in the restricted surface data record table in the database. If there are newly added record items in the restricted surface data record table, indicating that the road line to which the item belongs is a road line newly configured to be affected by the restricted surface area, then the road line can be used as the target road line. Alternatively, if it is retrieved that the data of an item in the restricted surface data record table has changed, it indicates that the road line to which the item belongs is a road line that has been affected by the changed restricted surface area, and the road line can be used as the target road line.

[0071] For example, Figure 5 As shown, Figure 5: is a schematic diagram of the change in the spatial position of the road line in the embodiment of the present disclosure. The shaded area is the restricted surface area. Road line 1 was originally outside the restricted surface area, that is, road line 1 was originally a road line affected by the non-restricted surface area. After the spatial position of road line 1 is changed, the spatial position of road line 1 changes to within the restricted surface. Then, road line 1 is the newly configured road line affected by the restricted surface area, and can be used as the target road line.

[0072] S405: The road change data of the target road line is used as the target surface data.

[0073] In the embodiment of the present disclosure, after the change data is parsed and processed as above to obtain a plurality of road change data corresponding to a plurality of road lines in the map, and a target road line is determined from the plurality of road lines, the road change data of the target road line can be used as target surface data, and the target surface data can be used to update the initial surface data of the restricted surface, so as to correct and update the data content of the effect of the restricted surface in the map.

[0074] The above-mentioned method parses and processes the change data to obtain multiple road change data corresponding to multiple road lines in the map, and determines the target road line from the multiple road lines, wherein the target road line is a road line that has been affected by the restricted surface area, or the target road line is a road line newly configured to be affected by the restricted surface area, and uses the road change data of the target road line as the target surface data, so that the required road change data of the target road line can be quickly parsed from the change data and used as the target surface data. Since the target road line is a road line related to the restricted surface, the road change data related to the restricted surface can be obtained in a timely and convenient manner, which can effectively improve the update efficiency of the restricted surface data, make the update of the restricted surface data more targeted, and improve the update effect of the restricted surface data.

[0075] S406: Determine whether the target road line satisfies the road line protection rule according to the target surface data.

[0076] Among them, the road line protection rule refers to the change identification rule set in advance for the target road line. The road line protection rule can, for example, be set to judge whether the target road line is a road line related to the boundary road line of the restricted surface, or it can also be set to judge whether it is necessary to trigger the linkage update of the road line affecting the restricted surface. There is no restriction on this.

[0077] In the above-mentioned embodiment of the present disclosure, after the road change data of the target road line is used as the target surface data, a judgment can be triggered based on the target surface data as to whether the target road line satisfies the road line protection rule. The target road line can be searched within a certain spatial range from the boundary road line of the restricted surface. If the target road line can be searched, it indicates that the target road line satisfies the road line protection rule. Alternatively, the target surface data can be compared with relevant items in the restricted surface data record table in the database. If items related to the target surface data are found in the restricted surface data record table in the database, it indicates that the target road line to which the target surface data belongs satisfies the road line protection rule.

[0078] In other embodiments, after obtaining the road change data of the target road line as the target surface data, it can be determined whether it is necessary to trigger a linkage update of the road line affected by the restricted surface. If it is necessary to trigger a linkage update of the road line affected by the restricted surface, it indicates that the target road line to which the target surface data belongs satisfies the road line protection rules.

[0079] Optionally, in some embodiments, when determining whether the target road line satisfies the road line protection rules based on the target surface data, a buffer surface area can be determined from the restricted surface area, and whether the target road line satisfies the road line protection rules can be determined based on the target surface data and the buffer surface area, thereby determining whether the target road line satisfies the road line protection rules within the buffer surface area. Since the buffer surface area is divided from the restricted surface area, it is avoided to judge all the road lines within the restricted surface, effectively reducing the computing resources consumed when processing the changed data, and helping to improve the data update processing efficiency of the restricted surface.

[0080] The buffer surface area refers to the area divided inward according to the boundary road line of the restricted surface, which is used to identify the changed road lines related to the restricted surface.

[0081] In the embodiment of the present disclosure, when determining the buffer surface area from the restricted surface area, a width value may be set, and a circular area is divided inwardly from the boundary of the restricted surface according to the width value as a buffer area. For example, Figure 6 As shown, Figure 6 is a schematic diagram of the buffer surface area division in the embodiment of the present disclosure, Figure 6 The shaded area in the figure is the buffer area. The width can be set to 30 meters, and then a ring area is divided inward from the boundary of the restricted area. This ring area can be used as the buffer area.

[0082] In other embodiments, the width of the buffer surface area may be adaptively configured according to actual needs, and then a ring area of ​​corresponding width may be divided inward from the restricted surface area as the buffer surface area, and there is no limitation on this.

[0083] In the disclosed embodiment, after determining the buffer surface area from the restricted surface area, it is possible to determine whether the target road line satisfies the road line protection rules based on the target surface data and the buffer surface area, and the target road line can be searched within the buffer surface area. If the target road line can be found, it indicates that the target road line satisfies the road line protection rules. Alternatively, the target surface data can be compared with the table items related to the buffer surface area in the restricted surface data record table in the database. If the table items related to the target surface data are found in the table items related to the buffer surface area, it indicates that the target road line to which the target surface data belongs satisfies the road line protection rules.

[0084] Optionally, in some embodiments, if the target road line is a road line newly configured to be affected by the restricted surface area, then when the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, it is directly determined that the target road line satisfies the road line protection rules, thereby determining whether the target road line satisfies the road line protection rules based on the endpoints involved in the target road line. The change of the endpoints of the target road line can be identified in time, and then the effect of the restricted surface can be adjusted based on the endpoints involved in the target road line to ensure the accuracy of the restricted surface effect area.

[0085] The endpoints involved in the target road line are used to identify the starting and ending positions of the target road line.

[0086] In the disclosed embodiment, if the target road line is a road line newly configured to be affected by the restricted surface area, a determination is made as to whether the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area; if the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, it is directly determined that the target road line satisfies the road line protection rules.

[0087] For example, Figure 7 As shown, Figure 7 It is a schematic diagram of the change of the road line endpoints in the embodiment of the present disclosure. After the road line 5 is changed, the newly configured target road line affected by the restricted surface area is a road line with endpoints 7 and 8 as the starting and ending endpoints. Endpoints 7 and 8 are located within the boundary of the buffer surface area, and it is determined that the target road line meets the road line protection rules.

[0088] S407: If the target road line meets the road line protection rule, the initial surface data of the restricted surface is updated to the target surface data.

[0089] In the disclosed embodiment, it is possible to determine whether the target road line satisfies the road line protection rules based on the target surface data. If the target road line satisfies the road line protection rules, the corresponding table item data in the restricted surface data record table corresponding to the map can be modified. If it is necessary to remove the restricted surface area from the target road line, the corresponding table item can be deleted from the data record table. If it is necessary to add the road line that is not affected by the restricted surface to the restricted surface area, the corresponding table item can be added to the database record table to update the initial surface data of the restricted surface to the target surface data.

[0090] In this embodiment, by determining whether the target road line satisfies the road line protection rules based on the target surface data, and when the target road line satisfies the road line protection rules, the initial surface data of the restricted surface is updated to the target surface data, so that it is possible to determine whether the target road line satisfies the road line protection rules based on the target surface data, and when the target road line satisfies the road line protection rules, the restricted surface data is updated in a timely manner, which can ensure the accuracy of the updated and adjusted data, and assist in improving the accuracy of the target surface data after the restricted surface is updated.

[0091] In this embodiment, the change data is parsed to obtain a plurality of road change data corresponding to a plurality of road lines in the map, and a target road line is determined from the plurality of road lines, wherein the target road line is a road line that has been affected by the restricted surface area, or the target road line is a road line that is newly configured to be affected by the restricted surface area, and the road change data of the target road line is used as the target surface data, so that the road change data of the required target road line can be quickly parsed from the change data and used as the target surface data. Since the target road line is a road line related to the restricted surface, it is possible to obtain the road change data related to the restricted surface in a timely and convenient manner. Changing data can effectively improve the updating efficiency of restricted surface data, make the updating of restricted surface data more targeted, and improve the updating effect of restricted surface data. By determining whether the target road line meets the road line protection rules based on the target surface data, and when the target road line meets the road line protection rules, the initial surface data of the restricted surface is updated to the target surface data, so that it can be determined whether the target road line meets the road line protection rules based on the target surface data, and the restricted surface data is updated when the target road line meets the road line protection rules, which can ensure the accuracy of the updated and adjusted data and assist in improving the accuracy of the target surface data after the restricted surface is updated.

[0092] Figure 8 is a schematic diagram according to a third embodiment of the present disclosure.

[0093] like Figure 8 As shown, the map surface data processing method includes:

[0094] S801: Receive map change data.

[0095] S802: Acquire initial surface data of the restricted area in the map.

[0096] S803: Analyze the change data to obtain a plurality of road change data corresponding to a plurality of road lines in the map.

[0097] S804: Determine a target road line from among a plurality of road lines, wherein the target road line is a road line that has been acted upon by the restricted area, or the target road line is a road line that is newly configured to be acted upon by the restricted area.

[0098] S805: Use the road change data of the target road line as the target surface data.

[0099] S806: Determine a buffer surface area from the restricted area.

[0100] The description of S801 - S806 can be referred to the above embodiment for examples, and will not be repeated here.

[0101] S807: If the target road line is a road line affected by the restricted surface area, and the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, determine whether the target surface data matches the set change event.

[0102] Among them, the setting change event is a possible change event of the pre-set road line endpoints. The setting change event can, for example, be that one endpoint of the road line affected by the restricted area is changed to outside the restricted area, or both endpoints of the road line affected by the restricted area are changed to outside the restricted area, or other setting change events can be set according to actual scene requirements, and there is no restriction on this.

[0103] After determining the target road line from the multiple road lines and determining the buffer surface area from the restricted surface area, the disclosed embodiment can determine whether the target surface data matches the set change event. If the target road line is a road line affected by the restricted surface area, it can be determined whether the endpoints involved in the target road line indicated by the target surface data are located within the boundary of the buffer surface area. If the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, it can be triggered to determine whether the target surface data matches the set change event.

[0104] Optionally, in some embodiments, the target surface data includes: endpoint change data corresponding to at least one endpoint of the corresponding road line, wherein it is determined whether the target surface data matches the set change event. If, based on the endpoint change data, it is determined that at least one endpoint is changed to outside the boundary of the buffer surface area, then it is determined that the target surface data matches the set change event, thereby enabling timely identification of endpoint changes of road lines within the restricted surface area, and timely implementation of corresponding linkage adjustments to the restricted surface area when the endpoint changes to outside the buffer surface area, thereby avoiding omissions of road lines affected by the restricted surface and ensuring the accuracy of road lines affected by the restricted surface.

[0105] Among them, the target surface data includes: endpoint change data corresponding to at least one endpoint of the corresponding road line. The changed endpoint of the road line can be the starting endpoint or the ending endpoint of the road line, or both the starting endpoint and the ending endpoint of the road line can change. The endpoint change data can be the endpoint change data generated when the starting endpoint or the ending endpoint of the road line is changed to outside the boundary of the buffer surface area, or the endpoint change data generated when both the starting endpoint and the ending endpoint of the road line are changed to outside the boundary of the buffer surface area.

[0106] In the embodiment of the present disclosure, when judging whether the target surface data matches the set change event, it can be judged based on the endpoint change data whether at least one endpoint of the corresponding road line is changed to be outside the boundary of the buffer surface area. If the starting endpoint or the ending endpoint of the corresponding road line is changed to be outside the boundary of the buffer surface area, or the starting endpoint or the ending endpoint of the road line are both changed to be outside the boundary of the buffer surface area, it is determined that the target surface data matches the set change event.

[0107] For example, Fig. 9 As shown, Fig. 9 It is a schematic diagram of the endpoint change event in the embodiment of the present disclosure. When endpoint 1 of road line 1 is changed to outside the boundary of the buffer surface area, it can be determined that the target surface data matches the set change event in change state 1. When endpoint 1 and endpoint 2 of road line 1 are changed to outside the boundary of the buffer surface area in change state 2, it can be determined that the target surface data matches the set change event in change state 2.

[0108] S808: If the target surface data matches the setting change event, it is determined that the target road line satisfies the road line protection rule.

[0109] When determining whether the target surface data matches the set change event, the embodiment of the present disclosure may determine that the target surface data matches the set change event if it is identified that at least one endpoint of the target road line is changed to be outside the boundary of the buffer surface area. It is then determined that the target road line satisfies the road line protection rule, and the initial surface data of the restricted surface may then be updated to the target surface data.

[0110] S809: If the target surface data does not match the set change event, it is determined that the target road line does not satisfy the road line protection rule.

[0111] When determining whether the target surface data matches the set change event, the embodiment of the present disclosure determines that if no endpoint of the target road line is changed to be outside the boundary of the buffer surface area, the target surface data is determined not to match the set change event, and the target road line is determined not to satisfy the road line protection rule.

[0112] In the present embodiment, when the target road line is a road line affected by the restricted surface area, and the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, it is judged whether the target surface data matches the set change event. When the target surface data matches the set change event, it is determined that the target road line satisfies the road line protection rules. When the target surface data does not match the set change event, it is determined that the target road line does not satisfy the road line protection rules. Therefore, it is possible to determine whether the target road line satisfies the road line protection rules based on the matching situation of the target surface data and the set change event, thereby achieving more effective determination and processing of whether the target surface data satisfies the road line protection rules, and assisting in improving the data update effect of the restricted surface.

[0113] S810: If the target road line satisfies the road line protection rule, the initial surface data of the restricted surface is updated to the target surface data.

[0114] For example, Fig.10 As shown, Fig.10 It is a schematic diagram of the restricted surface update process in the embodiment of the present disclosure. After the external road line changes, the change data can be received, and the change data can be parsed to obtain the road line change data of the target road line. Then, the road line change data of the target road line can be reviewed and processed to determine whether the target road line meets the road line protection rules. The road line change data of the target road line that meets the road line protection rules is submitted to the task management platform, and the restricted surface area is automatically added or modified, and the relevant data in the restricted surface data record table in the database is updated to perform the restricted surface drawing process, so as to realize the correction and linkage update of the data content of the restricted surface effect in the map.

[0115] Optionally, in some embodiments, the initial surface data also includes: initial road line data of the restricted surface area, wherein the initial surface data of the restricted surface is updated to the target surface data, and the target area range corresponding to the restricted surface area can be determined based on the initial road line data and the road change data of the target road line, and the initial area range of the restricted surface area is adjusted to the target area range, so that the restricted surface can be corrected and drawn according to the initial road data and the road change data of the target road line, and the initial area of ​​the restricted surface can be updated and adjusted to the target area range, thereby realizing the coordinated update of the road line and the restricted surface area.

[0116] The initial surface data also includes: initial road line data of the restricted area, and the initial road line data may be data such as endpoint information of the road line before the road line data is modified.

[0117] In the disclosed embodiment, when the initial surface data of the restricted surface is updated to the target surface data, the initial area corresponding to the restricted surface area can be adjusted and modified according to the initial road line data and the road change data of the target road line to obtain the target area range corresponding to the restricted surface area, and the initial area range of the restricted surface area is adjusted to the target area range.

[0118] In this embodiment, the change data is parsed and processed to obtain multiple road change data corresponding to the multiple road lines in the map, and a target road line is determined from the multiple road lines, wherein the target road line is a road line that has been affected by the restricted surface area, or the target road line is a road line newly configured to be affected by the restricted surface area, and the road change data of the target road line is used as the target surface data, so that the required road change data of the target road line can be quickly parsed from the change data and used as the target surface data. Since the target road line is a road line related to the restricted surface, the road change data related to the restricted surface can be obtained in a timely and convenient manner, which can effectively improve the update efficiency of the restricted surface data, make the update of the restricted surface data more targeted, and improve the update effect of the restricted surface data. When the target road line is a road line affected by the restricted surface area, and the target surface data indicates that the endpoints involved in the target road line are located within the boundary of the buffer surface area, it is determined whether the target surface data matches the set change event. When the target surface data matches the set change event, it is determined that the target road line satisfies the road line protection rules. When the target surface data does not match the set change event, it is determined that the target road line does not satisfy the road line protection rules. Therefore, it is possible to determine whether the target road line satisfies the road line protection rules based on the matching situation of the target surface data and the set change event, thereby achieving more effective determination and processing of whether the target surface data satisfies the road line protection rules, and assisting in improving the data update effect of the restricted surface.
