Abstract

The invention provides a vehicle obstacle detection method and system. By means of a laser radar and a camera shooting device which are installed on a vehicle, images in the vehicle driving directionare obtained separately, the images are subjected to image feature extraction separately, obstacle information is determined on the basis of extracted image features, due to the fact that the laser radar can obtain images in a long range, obstacle detection is conducted by combining the images obtained through the laser radar with the images obtained through the camera shooting device, long-distance obstacles can be detected, a vehicle can have a far braking distance in the high-speed driving state, the phenomenon that due to the fact that the vehicle is late to brake, the vehicle impacts theobstacle is avoided, and the safety of driving of the vehicle is improved.

Description

technical field [0001] The present application belongs to the technical field of vehicle control, and in particular relates to a vehicle obstacle detection method and system. Background technique [0002] During the driving process of the vehicle, by detecting the obstacles around the vehicle and controlling the vehicle to avoid the obstacles after detecting the obstacles, the safe driving of the vehicle is guaranteed. [0003] An existing method for detecting obstacles around a vehicle is to collect images around the vehicle based on a camera installed on the vehicle, and determine whether there is an obstacle based on the collected images. Since the camera device can only collect images within a short range, the images collected based on the camera device installed on the vehicle are images within the short range of the vehicle. [0004] When the vehicle is running at high speed, the camera device installed on the vehicle collects images around the vehicle, and after dete...
