s101, acquiring convex hull map data of a working surface in a target area.
The working plane in the embodiment of the invention refers to a map area including at least one internal road, such as a cell, a school, a unit and the like.
The target area is an area in the map area, which may be large or small, but the target area needs to include at least one job surface for determining the job surface in the following, for example, the target area is x city x area, or the target area is a certain street office, a certain village, a certain town, and the like.
Specifically, the obtaining of the convex hull map data of the working surface in the target area may include: acquiring map quotient data of a target area; and extracting convex hull map data of the operation surface from the map quotient data according to the road attribute.
In the embodiment of the present invention, the map manufacturer data may be map data provided by a map supplier, for example, map data obtained after purchase from various map manufacturers is imported into a database and may be extracted for use.
For map quotient data, various road attributes appear, for example, which road is marked, whether the road is external road data such as a cell external road or not, meanwhile, because the map quotient data is external road data that some building clusters are divided into a working face area through a clustering and convex hull algorithm under a general condition, convex hull data corresponding to the working face area is working face convex hull map data.
S102, determining the working surfaces in the target area according to the convex hull map data of the working surfaces, wherein each working surface comprises at least one internal path.
And S103, creating work surface map data in the target area by taking the work surface as a unit.
In the embodiment of the invention, the convex hull map data of the operation surface in the target area is obtained; determining a working surface in the target area according to the convex hull map data of the working surface, wherein each working surface comprises at least one internal path; work surface map data in the target area is created on a work surface basis. In the embodiment of the invention, the working surface map data is manufactured by determining the working surface of the target area, so that the updating and online period of the internal road data of a single working surface is greatly shortened, the version inheritance problem is not required to be considered, the data quality problem of version difference fusion is avoided, and when the map business data cannot be acquired subsequently, the map business data can be continuously and independently used by matching with other external area map data mined by future autonomous tracks, and the availability of the map data is improved.
In some embodiments of the present invention, as shown in fig. 2, the determining a working surface in the target area according to the working surface convex hull map data in step S102 may include:
and S1021, determining a first operation surface in the target area according to the operation surface convex hull map data.
Specifically, because the clustering may be inaccurate in the convex hull map data of the working surface, the proposal mainly solves the problem of making the internal map data of the working surface, so that a working surface area without an internal path in the convex hull map data of the working surface can be eliminated, and each working surface comprises at least one internal path, namely each working surface in the first working surface comprises at least one internal path.
And S1022, acquiring the data information of the work surface stored in the target area.
The data information of the job surface stored in the target area may include at least one of list information of the job surface stored in the target area, image data of the job surface stored in advance in the target area, a building layout of a cell in which buildings are completed in the target area, and the like, and the second job surface in the target area may be determined in step S1023 by the data information.
And S1023, determining a second working surface in the target area according to the data information of the working surface.
And S1024, taking a union of the first working surface and the second working surface as the working surface in the target area.
In the embodiment of the present invention, all the operation surfaces in the target area need to be determined, and a union of the first operation surface and the second operation surface may be taken as the operation surface in the target area.
In some embodiments of the present invention, when the data information of the working planes saved in the target area includes list information of the working planes saved in the target area, the list information includes each working plane and range data of each working plane, the range data of the working planes includes external path information corresponding to each working plane in the target area, and the external path information is used for defining the working plane defined by the current working plane. In this case, the acquiring data information of the job plane stored in the target area may include: acquiring the list information of the saved operation surface in the target area; the determining a second operation surface in the target area according to the data information of the operation surface may include: and determining a second operation surface in the target area according to the range data in the list information. The list information of the working surface comprises range data of the working surface, and the range data of the working surface comprises external path information corresponding to each working surface in the target area, so that the area corresponding to the defined working surface can be determined directly through the list information.
In other embodiments of the present invention, when the data information of the job surface saved in the target area includes job surface image data saved in advance in the target area, the acquiring the data information of the job surface saved in the target area may include: and acquiring the working face image data pre-stored in the target area. In this case, the determining a second work surface in the target area according to the data information of the work surface includes: and acquiring a working face defined in the target area by a user according to the working face image data, and taking the defined working face as a second working face in the target area. Specifically, the image data of the work surface and a map of the target area may be displayed on the terminal of the operation user, and the user may define the work surface area in the target area according to the image data of the work surface. The image data of the working surface may be an image or video data of the working surface, and for example, assuming that the image data of the working surface is a video image of a cell a, images of respective areas of the cell are shown therein, so that a user can view and confirm the area of the cell a, and further define an area corresponding to the cell a on a target area as the working surface corresponding to the cell a. In the case of the circling operation, a plurality of regions may be circled at a time, or one region may be circled at a time, and when the circling operation is completed, the second operation surface is a region including all the circled regions.
Since, in general, the majority of the working plane of an area includes cells, in other embodiments of the present invention, when the data information of the working plane stored in the target area includes a building plan of a cell with completed buildings, the acquiring the data information of the working plane stored in the target area includes: and acquiring a cell building planning map of the completed building in the target area. And the step of determining a second working surface in the target area according to the data information of the working surface may include: and determining a second working surface in the target area according to the cell building planning diagram of the completed building. Since there is generally clear cell area division in the cell architectural planning map, corresponding to a cell area in a target area, a cell in the target area, that is, a working plane corresponding to the cell, can be quickly determined by, for example, a path outside the cell in the cell architectural planning map.
According to map management data, for map sheets with centralized AOI of a city center, the data volume is increased progressively, and when the map data is manufactured, the whole operation period is limited by the operation period of the map sheets; the embodiment of the invention manages according to the operation surface so as to save the operation period.
Specifically, in the embodiment of the present invention, as shown in fig. 3, the creating work surface map data in the target area in the unit of work surface in step S103 may include:
and S1031, dividing the working surface in the target area into a plurality of task sets, wherein each task set comprises at least one working surface.
S1032 allocates the task sets to task receiving objects, and creates work surface map data according to the work surfaces in the task sets allocated by the task receiving objects.
The plurality of task receiving objects may be terminals corresponding to a plurality of task completors.
The embodiment of the invention manages according to the operation surface, and the former picture can be arbitrarily divided into a plurality of task receiving object operations, thereby greatly shortening the operation period and the online time.
After each task receiving object completes the corresponding production of the map data of the working face, the method in the embodiment of the invention may further include: and receiving a plurality of job face map data sent by a plurality of task receiving objects, and compiling the plurality of job face map data to derive format data which can be fused with map quotient data. The map data of the working face manufactured in the way can be fused with the map data of a map maker to form a data specification which accords with path planning, and then the data specification is released to an on-line application service or a Tencent cloud application service and the like. On one hand, the map is not required to be completely manufactured by an enterprise, on the other hand, the map is convenient for the enterprise to use, and the map of the working face can be updated and manufactured at any time.
Since the work surface includes an internal path and an external path outside the work surface, and there is a possibility that the created work surface map data is not merged with the external path, it is possible to check the pre-hang processing between the internal path and the external path before compiling the work surface map data. The pre-hanging processing and checking of the internal path and the external path specifically meets the following requirements: the position of the inner path of the working surface is required, and the inner path belonging to the working surface is required to be completely positioned in the working surface; the road for connecting the internal road and the external road can be partially positioned in the working plane; in addition, the inner road and the road except the working surface are in normal level crossing relation, and a gland can not exist; the internal road and the external road cannot be overlapped.
In the embodiment of the invention, because the map data is updated frequently, and different job-side data can be updated, the job-side map can be independently manufactured according to the updated job-side. That is, in some embodiments of the present invention, the method for generating map data may further include: determining a target operation surface of the map data to be updated in the target area; making map data of a target operation surface; and compiling the map data of the target working face to derive format data which can be fused with the map quotient data. At the moment, the map data of one or more operation surfaces can be updated independently, so that the map updating period is greatly reduced, and the accuracy of the map data is ensured.
