Document Type and Number:
WIPO Patent Application WO/2021/189375
Kind Code:
A1
Abstract:
A method, apparatus, and system for filtering obstacle candidates determined based on outputs of a LIDAR device in an autonomous vehicle is disclosed. A point cloud comprising a plurality of points is generated based on outputs of the LIDAR device (610). One or more obstacle candidates are determined based on the point cloud (620). The one or more obstacle candidates are filtered to remove a first set of obstacle candidates in the one or more obstacle candidates that correspond to noise based at least in part on characteristics associated with points that correspond to each of the one or more obstacle candidates (630). One or more recognized obstacles comprising the obstacle candidates that have not been removed are determined (640). Operations of an autonomous vehicle are controlled based on the recognized obstacles (650).
