Abstract

The present disclosure provides a map construction method, device, electronic device and storage medium. The method includes the following steps: acquiring first point cloud data of a first map, wherein the first map is a closed-loop map; a data collection terminal The movement starts from the area corresponding to the first map, returns to the area corresponding to the first map after passing through the inter-ring area, and collects second point cloud data during the movement. The area is the area surrounded by the area corresponding to the first map; the second map is generated according to the second point cloud data; the first map and the The pose transformation parameters of the second map are performed; the coordinates of the first map and the second map are unified according to the pose transformation parameters to generate a target map. Generate an internal expansion map based on the original map to meet some new autonomous driving requirements.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, and in particular, to a map construction method, device, electronic device and storage medium. Background technique [0002] Autonomous driving has gradually become a hot technology. The realization of automatic driving technology is inseparable from the point cloud map. Therefore, if you want the vehicle to drive automatically in a certain area, you need to build a point cloud map in the area in advance. Therefore, the point cloud map is determined based on the initial requirements for autonomous driving, but the requirements for autonomous driving often change, so the original point cloud map cannot meet the changed requirements for autonomous driving. SUMMARY OF THE INVENTION [0003] The present disclosure provides a map construction method, device, electronic device and storage medium. [0004] Specifically, the present disclosure is achieved through the following tech...
