Abstract

The invention provides an obstacle type recognition method and device and an electronic device, and relates to the technical field of automatic driving. The method comprises the following steps of acquiring the detection data of a radar in a vehicle; judging whether an obstacle exists in front of the vehicle according to the detection data of the radar; if it is detected that the obstacle exists in front of the vehicle, tracking the detection data of the obstacle to generate the tracking information of the obstacle; and performing identification processing on the tracking information by usinga target classification model to determine the type of the obstacle. Therefore, through the obstacle type identification method, the virtual obstacle in the detection result is effectively filtered, and the detection precision of the radar and the overall environment perception capability of the automatic driving vehicle are improved.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to the field of automatic driving technology, and proposes an obstacle type identification method, device and electronic equipment. Background technique [0002] Autonomous vehicles mainly rely on the information processing system in the vehicle to control the movement of the vehicle. The information processing system in the car mainly includes an environment perception system, a path planning system, and a decision control system. In order to ensure vehicle safety, the environment perception system needs to have high accuracy, accurately describe the environment around the vehicle, and correctly generate an environment map, so as to ensure the accuracy of the path planning and decision-making control system. In the environmental perception system, autonomous vehicles mainly rely on various sensors to detect surrounding obstacles. Commonly used sensors mainly include lidar, millime...
