The invention discloses a vehicle braking early warning method, system and device based on a binocular stereo camera. current vehicle driving information; and according to the first target information and the second target information, combined with preset weights to obtain the perception result data of the target obstacle; thus based on the perception result data and the current vehicle driving information, output Braking commands and / or warning commands, so that the vehicle can adjust the driving state according to the corresponding commands. Thus, the technical problems of limited obstacle detection types and imperfect braking and early warning strategies in the prior art are solved.
Description
technical field [0001] The invention relates to the technical field of automatic driving, in particular to a vehicle braking early warning method, system and device based on a binocular stereo camera. Background technique [0002] In recent years, with the rapid development of AI technology and the country's attention to traffic safety, the Ministry of Communications has successively issued relevant standards to regulate and require the automatic emergency braking system (also known as AEBS) of vehicles involving active safety. In the prior art, the perception module of the vehicle automatic emergency braking system usually uses one or a combination of several types of sensors including monocular camera, millimeter-wave radar, single-line laser, lidar, and ultrasonic radar. [0003] However, these sensors have their own obvious drawbacks. Among them, the monocular camera can only identify and measure the distance of vehicles and pedestrians, and has no ability to detect oth...
