  • POSITIONING METHOD, APPARATUS, AND SYSTEM
    Publication number: 20220198706
    Abstract: A positioning method, a related apparatus, and a related device, can be applied to vehicle self-driving in the artificial intelligence field A positioning device corrects a low-precision first pose by using N first geometric features extracted from first point cloud data collected by a point cloud collection apparatus to obtain a high-precision second pose. Compared with point cloud data in the prior art, a geometric feature with a small data volume is used for positioning to greatly reduce a data operation amount so that time consumption of vehicle positioning is reduced, and real-time performance of positioning is enhanced.
