The invention discloses a vehicle braking early warning method, a system and a device based on a binocular stereo camera. The method comprises the steps of acquiring first target information within the detection range of the binocular stereo camera, second target information within the detection range of a millimeter wave radar and current vehicle driving information; according to the first targetinformation and the second target information, combining a preset weight to obtain sensing result data of a target obstacle; and outputting a braking instruction and / or an early warning instruction based on the sensing result data and the current vehicle driving information, so that the vehicle adjusts the driving state according to the corresponding instruction. Therefore, the technical problemsof limited obstacle detection types and incomplete 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 among monocular cameras, millimeter-wave radars, single-line lasers, lidars, and ultrasonic radars. [0003] However, these sensors have their own obvious disadvantages. Among them, the monocular camera can only identify and measure the distance of vehicles and pedestrians, and has no ability to detec...
