Title
(EN) MAP PARTITION SYSTEM FOR AUTONOMOUS VEHICLES
(ZH) 用于自动驾驶车辆的地图分区系统
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).
(ZH) 系统识别通过ADV导航出的道路,该道路由来自一个或多个LIDAR传感器的一个或多个点云捕获(2601)。系统从点云提取所识别道路的道路标记信息,所述道路标记信息描述所识别道路的一个或多个道路标记(2602)。系统基于道路标记将道路划分成一个或多个道路分区(2603)。系统基于道路分区生成点云地图,其中,利用点云地图来感知ADV周围的驾驶环境(2604)。
