Abstract
The invention relates to the technical field of unmanned driving, in particular to a vector map updating method, system and device in an unmanned mine scene and a medium. The method comprises the following steps: firstly, preprocessing original point cloud data according to the current pose of the unmanned vehicle; filtering a dynamic object, and calculating a terrain contour; and finally, performing Boolean operation on the terrain contour and the high-precision map to obtain incremental update of the high-precision map, thereby realizing light-weight and high-efficiency update of the high-precision map. The problem that the updating efficiency is low when a vehicle contour scheme is adopted is solved. The updating range is only limited to the measurement distance of the laser radar, and a large-range map can be updated through one-time calculation; the calculation is simple and the calculation efficiency is high.
