Abstract

The present invention provides a parking lot map construction method, system, mobile terminal and storage medium. The method includes: when any vehicle is in the map construction mode, acquiring the motion posture of the vehicle and the surrounding image of the vehicle and extracting landmark information; based on the SLAM algorithm , generating a landmark map and a vehicle trajectory according to the motion posture of the vehicle and the landmark information; generating a grid map according to the vehicle trajectory and the detected drivable area; when the vehicle is driving in different areas of the parking lot, the map construction process is performed cyclically , forming a local or global parking lot map. The invention provides effective means for constructing parking lot maps and maps.

Description

technical field [0001] The invention relates to the field of computer communication and network security, and in particular to a method, system, mobile terminal and storage medium for constructing a parking lot map.
