Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The embodiment of the disclosure first provides a road data processing method, as shown in fig. l, including:
step S11: acquiring first map data at two ends of a target road section and reference data for assisting in generating second map data of the target road section under the condition that the target road section is an unopened road section;
step S12: second map data of the target link is generated based on the first map data and the reference data.
In the present embodiment, in the case where the target link is an unopened link, it may refer to the case where the target link is a link where no traffic is started. As shown in fig. 5, the target road segment may be a road segment that is newly built or has not yet started to pass, and has not yet been included in the electronic map.
In other implementations, step S11 and step S12 may also be segments that are not yet built at the target segment. For example, the target link may be a link for which a specific construction plan already exists, or may be a link for which a partial construction work is completed.
In this embodiment, the first map data at both ends of the target road segment may be related data of other road segments that are connected at both ends of the target road segment and that have been opened. For example, the first map data may be at least one of position-related data, extended shape-related data, height-related data, road attribute-related data, road traffic sign data of a road on which traffic has started at both ends of the target link.
The first map data at two ends of the target road section may be obtained by extracting part of map data corresponding to two ends of the target road section from the existing electronic map.
In the present embodiment, the reference data for assisting in generating the second map data of the target link may be any data that can be converted into data related to the target link in the electronic map. For example, the image data on the road, the speed planning data around the road, the building planning data, the spandrel column data of the expressway, the shape and position data of other road sections which are already opened and paired with the target road section, and the like, which are collected by the pedestrian by a manual manner, may be specifically mentioned.
The second map data of the target link may be generated from the first map data and the reference data by integrating the first map data and the reference data.
In one possible implementation, the reference data may be data of a position, a number of lanes, a shape, and the like of the target link acquired by means of photographing, remote measurement, and the like at both ends of the target link in a case where the target link cannot be accessed. When the second map data is generated, the road line data of the target road section can be estimated according to the reference data, and the second map data is generated according to the estimated road line data.
In other implementations, to avoid electronic map navigation using data of unopened segments for route planning when the target segment is unopened, navigation markers may be added to the second map data. The navigation mark is used to disable navigation from using the second map data.
In another possible implementation, a source marker may be added to the generated second map data according to the source of the reference data. The source mark is used for representing the acquisition path or the data source of the reference data, and the accuracy of the second map data can be different due to the fact that the reference data of different sources can cause the difference, so that a user can estimate the accuracy of the second map data approximately according to the source mark.
In another possible implementation, in case the target road segment is a new road segment that has been completed, a tag that is temporarily not reference data for navigation may be added to the second map data. The tag may be used to indicate that navigation of the second map data of the target link is prohibited, or may indicate that navigation of the second map data of the target link is possible with a certain authority. When the electronic map data is used, corresponding permission is acquired after a map navigation instruction is received, and under the condition that certain permission is met, the second map data can be adopted for navigation so as to realize special use requirements of emergency situations such as rescue, disaster relief, epidemic prevention, capturing, fire fighting and the like, and the most efficient and convenient route can be determined according to information such as distance, road congestion degree and the like in the emergency situations by combining the second map data with other map data.
In yet another possible implementation manner, a completion flag may be added to the second map data according to the construction completion degree of the target road segment when the reference data is acquired, for example: different colors, lines, etc. are used. After the second map data is generated, information such as the acquisition date of the reference data may be added. Specifically, for example, when the first completion flag indicates that the reference data is acquired, the construction of the roadbed or the road bearing support column is not completed on the target road section; when the second completion mark is adopted to indicate that the reference data is acquired, the construction of the roadbed or the road bearing support column is completed on the target road section, but the construction of other parts is not completed; when the third completion mark is adopted to indicate that the reference data is acquired, the target road section is already built, but cannot be safely passed because the final stabilization or other works are not completed; and when the fourth completion mark is adopted to indicate that the reference data is acquired, the target road section is already constructed and is in a state of meeting the safe passing condition. The completion flag may indicate not only the degree of completion but also indirectly the degree of accuracy of the second map data, and the higher the degree of completion when the reference data is acquired, the higher the accuracy of the second map data.
In still another possible implementation manner, special traffic indication information such as speed limit information of front and rear road segments of the target road segment may be obtained according to the first map data of two ends of the target road segment, and special traffic indication information such as speed limit information of the target road segment may be generated according to the special traffic indication information such as speed limit information. For example, if there is an accident-prone reminder in both the front and rear links of the target link, the accident-prone reminder may be added to the second map data. For another example, if the speed limit information of the front link of the target link defines the speed as a first speed and the speed limit information of the rear link of the target link defines the speed as a second speed, the speed limit information of the target link may be preset so as to define the speed as the lower value of the first speed and the second speed.
In yet another possible implementation, the second map data may be modified by acquiring modification information submitted by the user after the second map data is generated, and modifying the second map data according to the modification information. Thus, the accuracy of the second map data can be improved with the aid of the user entering the target road section.
In still another possible implementation manner, whether the second map data is adopted in navigation may be determined according to a travel mode selected by the user and an opening condition of the target road section.
According to the method and the device for updating the electronic map, map data of the target road section can be generated before the target road section does not start to pass for the first time, so that when the target road section passes for the first time, a user can immediately use the electronic map to navigate the target road section, update of the electronic map is prevented from being delayed from using an actual road, real-time performance of update of the electronic map data is improved, and user experience is improved.
In one embodiment, generating second map data of the target link from the first map data and the reference data, as shown in fig. 2, includes:
step S21: generating road line data of the target road section according to the first map data and the reference data;
step S22: determining position-related data of two ends of the target road section according to the first map data;
step S23: and generating second map data according to the position related data and the road line data at the two ends.
The road line data of the target link may be line data representing the target link having a certain width on the display interface of the electronic map. The line data may be a line for representing the edges of the two sides of the target road segment, that is, representing the boundaries of the left and right sides of the target road segment, on the display interface of the electronic map.
In this embodiment, the position data at the end point of the target link may be data such as the shape, angle, etc. of the road line near the end point of the target link. The method can be used for enabling the road line data of the target road section to be smoothly added into the electronic map.
In one possible implementation, the second map data is generated according to the position data and the road line data at the end point, and the position data and the road line data at the end point may be spliced to obtain the second map data.
In this embodiment, the road line data of the target link and the position data of both ends of the target link are determined according to the reference data and the first map data, so that the second map data can be normally used in the electronic map.
In one embodiment, the reference data of the target link includes: map data of a link associated with the target link; generating road line data of the target road segment according to the first map data and the reference data, including:
copying the map data of the associated road section which has started to pass to the position of the target road section in the map to obtain copy data;
obtaining road line data according to the copied data;
map data of a link associated with a target link includes a link parallel to the target link or a front-rear link of the target link.
In this embodiment, the road segment associated with the target road segment may be a road segment associated with the target road segment that has started to pass.
In this embodiment, the road section associated with the started traffic may be another road section that may have the same shape as the target road section. The copying of the map data of the associated road segment that has started to pass to the position of the target road segment in the map may be copying of the map data of the associated road segment that has started to pass to the position of the target road segment in the map, either partially or entirely.
In another possible implementation, the road segments associated with the target road segment that have begun to travel may also be other same kind of opened road segments that correspond to the attributes of the target road segment. For example, the intersection of an overpass and the like can be adopted.
In another possible implementation, the road segment associated with the target road segment that has begun to travel may also be an opened road segment that is similar to the surroundings of the target road segment. For example, there may be some communities or buildings around the target road segment, where the communities or buildings have a layout corresponding to an opened road segment, and the opened road segment may be a road segment that has begun to travel in association with the target road segment.
In this embodiment, when the target link cannot be accessed, as shown in fig. 4, the road line data of the target link may be generated by a copying method when reference data such as road materials cannot be acquired in the field. The copied part can be a traffic road, can be copied to an unvented part in parallel according to the shape of the traffic road according to the shape acquired by an in-situ GPS (Global Positioning System ) to achieve the whole road acquisition.
In another possible implementation, the road segment associated with the target road segment may be a road segment associated with the target road segment that does not begin traffic but has completed map data generation.
In this embodiment, map data of a road segment associated with a target road segment is copied to obtain road line data of the target road segment, so that the road line data of the target road segment can be obtained without entering the target road segment, and certain accuracy of the road line data can be ensured.
In one embodiment, the map data of the associated road segment is copied to the position of the target road segment in the map to obtain the road line data, as shown in fig. 3, including:
step S31: in the duplication state, determining a duplicated first road line in the associated road section according to the selection instruction, wherein the duplication state is determined according to the selected state of a duplication button in the road data processing interface;
step S32: according to the moving instruction of the first road line, the first road line is moved to the position of the two side edges of the road surface of the target road section, and a second road line is obtained;
step S33: and taking the second road line as road line data.
In this embodiment, the copy state may be a state in which the copy button is selected. The selection instruction may be an instruction to circle the first road line.
In a specific example, as shown in fig. 6, in the map information processing interface, the user may enter the copy state by clicking the selected copy button, and upon detecting that the copy button is in the selected state, the user may correspondingly enter the copy state. The user may also select the duplicate object by clicking or circling, and move the selected duplicate object by pressing a mouse button until the duplicate object is pulled to the correct position.
In this embodiment, the road line data of the target road segment may be generated by copying and moving, so that the road line data of the target road segment may be obtained without collecting the road material of the target road segment in the field.
In one embodiment, obtaining second map data from the end point data and the road line data includes:
splicing the second road line with the line corresponding to the endpoint data to obtain a spliced line;
and carrying out smooth processing on the spliced lines to obtain second map data.
In one possible implementation manner, the second road line may be extended in two directions, the extended second road line and the end point data are spliced in an overlapping manner, and the second road line is adjusted according to the overlapping degree of the end point data and the second road line. If the line corresponding to the end point data is overlapped with the extending part of the second road line, sleeve adjustment on the second road line is not needed. For example, in the case where the second road line includes two parallel lines, if the distance between the lines corresponding to the end point data is greater than the distance between the portions of the second road line extending, the distance between the second road lines may be widened.
In this embodiment, the spliced lines are rounded, so as to obtain the second map data with smooth transition.
In one embodiment, the reference data includes: at least one of satellite image data of the target link and geographic environment reference data of the target link.
The satellite image data may be image data captured by a satellite.
The geographical environment reference data of the target link may be distribution data of the load-bearing struts of the target link that has been completed to be constructed, natural environment data around the target link, and the like. For example, if the target road section is sea on one side and mountain on the other side, the target road section may extend along the direction and line along which the coastline extends, or may extend straight along the direction along which the coastline extends. For another example, if the target road segment is a road segment on a river-crossing or river-crossing bridge, the target road segment may be a straight line between two shore starting points.
In this embodiment, the second map data can be determined according to the satellite image data or the reference data in the geographic environment where the target road section is located, so that the map data corresponding to the target road section can be determined without acquisition in the field.
In another implementation, the reference data of the target road segment may be various data, such as satellite image data, data photographed in the field, and the like. The GPS positioning auxiliary hand drawing, the existing road shape copying and other functions are utilized to complete the method for manufacturing the express way without passing through the vehicle.
The embodiment of the disclosure further provides a road data processing device, as shown in fig. 7, including:

a position unit 82 for determining position-related data of both ends of the target link based on the first map data;
