Automobile Braking Performance Detection System Based on Binocular Stereo Vision

Abstract

Braking performance is one of the important items of vehicle safety performance testing, and good braking performance is an important guarantee for vehicle safety driving. This paper mainly studies the vehicle braking performance detection system based on binocular stereo vision. The visual inspection system runs in Windows XP operating system. The stereo vision system software for automobile braking performance inspection is developed by using MATLAB and Visual C + +. At the same time, SQL Server 2005 database is used. When the vehicle speed reaches the set speed, manually disconnect the clutch on the bench, and give the driver the command to press down the brake pedal to make the four wheels rotate freely. At the same time, the acquisition system starts to collect braking data, observe the curve change trend in the main interface of the acquisition system, and debug repeatedly until it is consistent with the actual situation of automobile braking. In this paper, the binocular stereo vision ranging system has high accuracy in short distance ranging. The ranging error is less than 1% in 10 meters and less than 5% in 15 meters. The results show that the system designed in this paper has the advantages of low development cost, short cycle, easy function expansion, easy to carry and so on.
