Abstract

The invention discloses a map determination method and a map determination device. The map determination method comprises the steps of: rasterizing a target region, determining a terrain value corresponding to each grid according to a digital elevation model of the target region, and forming a terrain weight map; and determining a boundary vector diagram of the target region according to point cloud data of the target region. According to the map determination method, the terrain value information of the non-boundary grids and the modification information of the boundary grids are integrated,so that the determined electronic map can improve the map accuracy of the target region, and is suitable for automatic driving vehicles for mining areas.

Description

technical field [0001] The present invention relates to the fields of information processing and automatic driving, further relates to a method for determining a map, and also relates to a device and equipment for determining a map, and further relates to a method for automatically driving a mining vehicle. Background technique [0002] Autonomous driving technology has great potential to improve production efficiency and production safety. The key technologies of autonomous driving mainly include high-precision positioning, environment perception, decision-making planning, executive control, etc. Among them, the environmental perception module obtains the information around the vehicle through the on-board sensor, and describes other vehicles, pedestrians, road signs, etc. through a certain method, and the description results are used as important inputs for the decision-making planning module and the control module. [0003] At present, there are few methods for determini...
