The invention relates to a method for detecting a vehicle and surrounding obstacles by fusing a roadside laser radar and a video. According to the invention, roadside equipment is used for broadcasting road detection information to all motor vehicles, all the motor vehicles located in a target area share a high-harness laser radar, all the motor vehicles can utilize the laser radar to replace laser radars which should be originally installed on the motor vehicles, and the cost of roadside equipment containing the laser radar does not need to be borne by users of the motor vehicles. After the scheme is adopted, a motor vehicle does not need to be provided with any equipment similar to the laser radar, positioning of the vehicle and surrounding vehicles can be achieved by recognizing and matching license plate numbers, so that the vehicle refitting cost can be greatly reduced, meanwhile, equipment like arithmetic equipment used for achieving automatic driving can be guaranteed to acquireaccurate data, and the automatic driving function is achieved.
Description
technical field [0001] The invention relates to a method capable of locating the self-vehicle and surrounding obstacles so as to assist in realizing unmanned driving. Background technique [0002] Unmanned driving technology relies on self-driving cars. Existing self-driving cars rely on artificial intelligence, visual computing, lidar, monitoring devices and global positioning systems to work together, allowing computers to automatically and safely drive without any active human operation. Operate a motor vehicle. Among them, lidar is equivalent to the eyes of the vehicle and is an indispensable hardware device for automatic driving. Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, the...
