Abstract

The present application relates to a laser point cloud processing method, electronic device and storage medium, wherein the method includes: acquiring a first point cloud and a vehicle track corresponding to the first point cloud; extracting a second point cloud from the first point cloud , wherein, the height of each point in the second point cloud from the vehicle track is not greater than the preset height; each point in the second point cloud is address-coded, and the second point cloud is converted according to the address code value of each point obtained by address coding Each point in is grouped into multiple point cloud blocks; the polar coordinate data of each point in each point cloud block is obtained, and a file indexed by the address code value corresponding to each point cloud block is generated, wherein each point cloud block The file contains polar coordinate data for each point in the point cloud block. Through this application, the problem of large storage space occupied by the laser point cloud positioning layer is solved, and the storage space occupied by the laser point cloud positioning layer is reduced.

Description

technical field [0001] The present application relates to the field of computer vision, in particular to a laser point cloud processing method, an electronic device and a storage medium. Background technique [0002] Computer vision is a key technology in driverless technology. Among them, in the application of high-precision centimeter-level positioning in computer vision, the lidar point cloud positioning map plays a vital role. Due to the different centimeter-level positioning schemes developed by various companies and research institutes, the construction methods of the corresponding point cloud layers are also different. For example, Stanford University's method constructs a planar map that removes dynamic objects. In the map generated with a resolution of 5 cm, each grid (grid) stores the reflectivity intensity value of the laser at that location. After all objects above the ground are removed, the data per mile (about 1760 meters) is about 10MB. However, the schem...
