Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those 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 disclosed embodiment first provides a road data processing method, as shown in fig. l, including:
step S11: under the condition that the target road section is an unopened road section, acquiring first map data at two ends of the target road section and reference data for assisting in generating second map data of the target road section;
step S12: second map data of the target link is generated based on the first map data and the reference data.
In this embodiment, when the target road segment is an unopened road segment, the target road segment may be a road segment that does not start to pass through. As shown in fig. 5, the target link may be a link that is newly built or has not yet started to pass and has not yet been included in the electronic map.
In other implementations, steps S11 and S12 may also be that the target road segment is an incomplete link to be built. For example, the target road segment may be a road segment where a specific building plan already exists, or may be a road segment where a part of the building work is completed.
In this embodiment, the first map data at the two ends of the target road segment may be related data of other opened road segments connected to the two ends of the target road segment. For example, the first map data may be at least one of position-related data, extended shape-related data, altitude-related data, road attribute-related data, and road traffic sign data of a road on which passage has been started at both ends of the target link.
The first map data of the two ends of the target road section are obtained by extracting partial map data corresponding to the two ends of the target road section in the existing electronic map.
In the present embodiment, the reference data for assisting the generation of 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 data may be image data on a road, speed planning data around the road, building planning data, load bearing column data of an expressway, shape and position data of other opened road segments paired with a target road segment, and the like, which are manually collected by a pedestrian.
The second map data of the target link may be generated based on the first map data and the reference data, and the first map data and the reference data may be integrated to generate the map data of the target link.
In one possible implementation, the reference data may be data of the position, the number of lanes, the shape, and the like of the target link acquired by means of photographing, distance measurement, and the like at both ends of the target link in a case where the target link cannot enter. Therefore, 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 implementation manners, in order to avoid that the electronic map navigation uses data of the unopened road section for route planning when the target road section is unopened, a navigation mark can be added in the second map data. The navigation mark is used to disable navigation to employ the second map data.
In another possible implementation, a source flag 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 route or the data source of the reference data, and the accuracy of the second map data can be different due to the reference data of different sources, so that the user can roughly estimate the accuracy of the second map data according to the source mark.
In another possible implementation, in the case where the target road segment is a new road segment that has already been built, a label that is not temporarily used as reference data for navigation may be added to the second map data. The label may be used to indicate that the navigation of the second map data of the target road segment is prohibited, or indicate that the navigation of the second map data of the target road segment is possible under certain authority. Therefore, when the electronic map data is used, after a map navigation instruction is received, the corresponding authority is obtained, and under the condition that a certain authority is met, the second map data can be adopted for navigation so as to realize special use requirements of emergency situations such as emergency rescue, disaster relief, epidemic prevention, capture, fire fighting and the like, so that in the emergency situation, the most efficient and convenient route can be determined according to information such as distance, road congestion degree and the like by combining the second map data and other map data.
In another possible implementation manner, a completion flag may be added to the second map data according to the building completion of the target road segment when the reference data is acquired, for example: different colors, lines, etc. are used. Information such as the date of acquisition of the reference data may be added after the second map data is generated. For example, the first completion flag may be used to indicate that the construction of a roadbed or a load-bearing support column of the road is not completed in the target road segment when the reference data is acquired; 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 of the target road section is completed, 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 built, but the target road section cannot pass safely because the last stable or other work is not completed; and adopting a fourth completion mark to indicate that the target road section is built and is in a state of meeting the safe passing condition when the reference data is acquired. The completion flag may indicate not only the completion degree but also the accuracy degree of the second map data indirectly, and the higher the completion degree is when the reference data is acquired, the higher the accuracy of the second map data is.
In another possible implementation manner, special traffic indication information such as speed limit information of road sections before and after the target road section may be acquired according to the first map data at both ends of the target road section, and the special traffic indication information such as the speed limit information of the target road section may be generated according to the special traffic indication information such as the speed limit information. For example, if the accident outbreak prompt exists in the front road section and the rear road section of the target road section, the accident outbreak prompt can be added into the second map data. For another example, if the speed limit information of the road segment before the target road segment limits the speed to a first speed and the speed limit information of the road segment after the target road segment limits the speed to a second speed, the speed limit information of the target road segment may be preset to limit the speed to a lower value of the first speed and the second speed.
In yet another possible implementation manner, correction information submitted by the user may be acquired after the second map data is generated, and the second map data may be corrected according to the correction information. Thus, the accuracy of the second map data can be improved with the help of the user who enters the target road section.
In still another possible implementation manner, whether to use the second map data during navigation may be determined according to a travel mode selected by a user and an opening condition of the target road segment.
According to the method and the device, the 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, the situation that the updating of the electronic map lags behind the use of an actual road is avoided, the real-time performance of the updating of the electronic map data is improved, and the user experience is improved.
In one embodiment, generating second map data of the target link based on 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 with a certain width on a display interface of the electronic map. The line data may also be lines for representing road edges on both sides of the target road segment on the display interface of the electronic map, that is, line data representing boundaries on both left and right sides of the target road segment.
In this embodiment, the position data at the end point of the target link may be data such as the shape and angle of a road line near the end point of the target link. The method can be used for adding the road line data of the target road section into the electronic map in a smoother way.
In a possible implementation manner, 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 for the target link includes: map data for a road segment associated with the target road segment; generating road line data of the target link according to the first map data and the reference data, including:
copying the map data of the related road section which starts to pass to the position of the target road section in the map to obtain copied data;
obtaining road line data according to the copied data;
the map data of the link associated with the target link includes a link parallel to the target link or links before and after 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 and having started to pass through.
In this embodiment, the associated road segment that has started to pass through may also be other road segments that may have the same shape as the target road segment. The copying of the map data of the associated passage-started link to the position of the target link in the map may be to copy part or all of the map data of the associated passage-started link to the position of the target link in the map.
In another possible implementation, the road segment that has started to pass associated with the target road segment may also be other opened road segments of the same kind that correspond to the attribute of the target road segment. For example, the intersection of the overpass can be used.
In another possible implementation, the route segment that has started to pass through that is associated with the target route segment may also be an opened route segment that is similar to the surrounding environment of the target route segment. For example, if there are communities or buildings around the target road segment and the layouts of the communities or buildings correspond to an opened road segment, the opened road segment may be a road segment which is associated with the target road segment and has started to pass through.
In the present embodiment, when the target link cannot enter, as shown in fig. 4, and reference data such as a road material cannot be collected in the field because the target link cannot enter, the road line data of the target link may be generated by copying. The copied part can be a road with traffic, and can be copied to the part with traffic not passing in parallel according to the shape obtained by a Global Positioning System (GPS), so as to achieve the whole road collection.
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 has not started to pass through but has completed map data generation.
In this embodiment, the map data of the road segment associated with the target road segment is copied to obtain the 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, copying the map data of the associated link to the position of the target link in the map to obtain the road line data, as shown in fig. 3, includes:
step S31: determining a first road line to be copied in the associated road section according to the selection instruction in a copying state, wherein the copying state is determined according to the selected state of a copying button in a road data processing interface;
step S32: moving the first road line to positions where edges on two sides of the road surface of the target road section are located according to the moving instruction of the first road line to obtain a second road line;
step S33: and taking the second road line as the 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 for circling the first road strip.
In a specific example, as shown in fig. 6, in the map information processing interface, the user may enter the copy state by clicking a selected copy button, and when it is detected that the copy button is in the state of being changed to the selected state, the copy state is correspondingly entered. The user can select the copy object by clicking or circling, and the selected copy object is moved by pressing a mouse button until the copy object is pulled to the correct position.
In this embodiment, the road line data of the target link may be generated by copying and moving, so that the road line data of the target link may be obtained without collecting road materials of the target link in the field.
In one embodiment, obtaining the 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 end point data to obtain a spliced line;
and carrying out smoothing treatment on the spliced lines to obtain second map data.
In a possible implementation manner, the second road line may be extended in two directions, the extended second road line and the endpoint data are spliced in an overlapping manner, and the second road line is adjusted according to the overlapping degree of the endpoint data and the second road line. If the line corresponding to the end point data is overlapped with the extended part of the second road line, the second road line does not need to be adjusted in a sleeving manner. For example, in a 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 extended portions of the second road line, the distance between the second road lines may be widened.
In this embodiment, the spliced lines are subjected to smoothing processing, so as to obtain smoothly-transitioned second map data.
In one embodiment, the reference data comprises: at least one of satellite imagery data of the target road segment and geo-environmental reference data of the target road segment.
The satellite image data may be image data captured by a satellite.
The geographic environmental reference data of the target road segment may be distribution data of the load-bearing pillars of the target road segment that has been built, natural environmental data around the target road segment, and the like. For example, if the target road segment has a sea on one side and a mountain on the other side, the target road segment may extend along a direction and a 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 or a river-crossing bridge, the target road segment may be a straight line between the starting points of the two banks.
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 actually acquiring the second map data.
In another implementation, the reference data of the target link may be various data, such as satellite image data, data captured in the field, and the like. The method for manufacturing the expressway with the traffic not passing through is completed by utilizing the functions of GPS positioning auxiliary hand-drawing, copying the shape of the existing road and the like.
An embodiment of the present disclosure further provides a road data processing apparatus, as shown in fig. 7, including:

and a generating module 72, configured to generate second map data of the target road segment according to the first map data and the reference data.
