发明名称 Construction zone object detection using light detection and ranging
摘要 Methods and systems for construction zone object detection are described. A computing device may be configured to receive, from a LIDAR, a 3D point cloud of a road on which a vehicle is travelling. The 3D point cloud may comprise points corresponding to light reflected from objects on the road. Also, the computing device may be configured to determine sets of points in the 3D point cloud representing an area within a threshold distance from a surface of the road. Further, the computing device may be configured to identify construction zone objects in the sets of points. Further, the computing device may be configured to determine a likelihood of existence of a construction zone, based on the identification. Based on the likelihood, the computing device may be configured to modify a control strategy of the vehicle; and control the vehicle based on the modified control strategy.

主权项 1. A method, comprising: selecting, by a computing device of a vehicle, a portion of a three-dimensional (3D) point cloud representing an area within a predetermined threshold distance from a surface of a road of travel of the vehicle; identifying one or more construction zone objects in the selected portion; determining, using the computing device, a likelihood of existence of a construction zone based on the identified one or more construction zone objects; in response to the likelihood exceeding a threshold likelihood, determining a severity of road changes based on a number and locations of the one or more construction zone objects; and controlling, using the computing device, the vehicle based on the likelihood of existence of the construction zone and the severity of road changes.
