Abstract

The invention belongs to an automobile safety system, in particular to an automobile active safety control system based on binocular stereo vision and a control method thereof. The automobile active safety control system based on the binocular stereo vision comprises input equipment, output equipment and a processor, wherein the output equipment is a brake actuator. The automobile active safety control system is characterized in that the input equipment comprises a binocular camera, a speed sensor and a brake information sensor; the input equipment, the processor and the output equipment are electrically connected in sequence; the binocular camera is arranged in front windshield glass of an automobile, and the speed sensor is taken from the original automobile and is arranged in a gearbox generally. The invention has the advantages that the precision of binocular stereo vision distance measurement is higher than that of a monocular machine and a barrier is accurately positioned, therefore, the mounting requirement on the camera is low. The invention is simple and easy to implement; the processing speed reaches the real-time requirement, the distance measurement precision is high and the requirement in the automobile active safety aspect is satisfied.
