Problems solved by technology
However, the aerial survey equipment used in this plan is expensive, and the price of each aerial survey is tens of thousands of yuan. According to the production progress of the open-pit mine, an aerial survey is required every week
After each aerial survey is completed, professional cartographers are required to manually draw high-precision vector maps, which is inefficient

Embodiment Construction
[0061] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the examples of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0062] like figure 1 As shown, this embodiment provides a vector map generation system for mines, which mainly includes a vehicle-mounted data acquisition unit, a vector map generation unit and an interaction unit.
[0063] Among them, the vehicle-mounted data acquisition unit is mainly used to collect the surrounding environment data information of the place where the unmanned mine car passes; the vehicle-mounted data acquisition unit includes 360° l...

The invention discloses a vector map generation method for a mine field, which mainly generates a first point cloud map through data collected by a sensor, and identifies edge information of a road where an unmanned mine car passes through through methods of road edge extraction and the like, thereby obtaining a high-precision vector map with the road information. The invention further discloses a vector map generation system for the mine field. According to the method provided by the invention, the sensor of the unmanned mine car can be adopted, the high-precision vector map is automatically generated according to the data acquired by the unmanned mine car in the driving process without manual intervention, and the drawing efficiency of the high-precision vector map is greatly improved. And aerial survey equipment is not needed, so that the mapping cost of the map is greatly saved.
Description
technical field [0001] The invention belongs to the field of data processing, and in particular relates to a vector map generation method, system and computer system for mines. Background technique [0002] With the rapid development of unmanned driving technology, more and more ore mining companies have begun to carry out unmanned transformation of mines. Unmanned mining vehicles play a core role in the current unmanned transformation of mines. The mine is an unmanned and closed environment. The unmanned mining vehicles mainly face two technical difficulties. The first is how to carry out accurate centimeter-level positioning on unstructured roads, and the second is how to continue to mine with the mine. Realize path planning on changing unstructured roads. [0003] In order to solve the above problems, the existing solution is to use aerial survey equipment to regularly scan high-precision point cloud maps of open-pit mines, and then professional cartographers manually d...
