Title:
MAP PARTITION SYSTEM FOR AUTONOMOUS VEHICLES
Document Type and Number:
WIPO Patent Application WO/2020/154967
Kind Code:
A1
Abstract:
A system identifies a road to be navigated by an ADV, the road being captured by one or more point clouds from one or more LIDAR sensors (2601). The system extracts road marking information of the identified road from the point clouds, the road marking information describing one or more road markings of the identified road (2602). The system partitions the road into one or more road partitions based on the road markings (2603). The system generates a point cloud map based on the road partitions, where the point cloud map is utilized to perceive a driving environment surrounding the ADV (2604).
