Title
(EN) MAP PARTITION SYSTEM FOR AUTONOMOUS VEHICLES
(FR) SYSTÈME DE PARTITION DE CARTE POUR VÉHICULES AUTONOMES
Abstract
(EN) 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).
(FR) Un système identifie un itinéraire à parcourir par un ADV, l'itinéraire étant capturé par un ou plusieurs nuages de points à partir d'un ou de plusieurs capteurs LIDAR (2601). Le système extrait des informations de marquage d'itinéraire de l'itinéraire identifié à partir des nuages de points, les informations de marquage d'itinéraire décrivant un ou plusieurs marquages d'itinéraire de l'itinéraire identifié (2602). Le système partitionne l'itinéraire en une ou plusieurs partitions d'itinéraire sur la base des marquages d'itinéraire (2603). Le système génère une carte de nuages de points sur la base des partitions d'itinéraire, la carte de nuages de points étant utilisée pour percevoir un environnement de conduite entourant l'ADV (2604).
