Research on Autopilot Vehicle Ranging System Based on Binocular Vision

Abstract

With the rapid development of communication technology and computer technology, autonomous driving technology has become a field of great concern. Environmental perception technology is one of the key technologies of autonomous vehicles. Binocular stereo vision technology has become an indispensable research content in environmental awareness technology because of its unique advantages. In this paper, the key technologies such as binocular ranging principle, camera calibration, stereo correction and stereo matching are studied. Based on this, a binocular stereo vision ranging system based on MATLAB and OpenCV is designed. Camera calibration is performed by MATLAB, and the calibration results are imported into OpenCV for stereo correction and stereo matching to solve the distance between the target object and the camera. The experimental results show that the measurement error is less than 2% within a distance of 30 meters.
