Research on Target Ranging Method Based on Binocular Stereo Vision

Binocular vision is an important part of machine vision. This paper focuses on how to obtain the position information of the target in the three-dimensional space and designed a ranging method based on binocular stereo vision through the combination of software and hardware. Firstly, the binocular camera is calibrated to get the internal and external parameters, then the disparity map is obtained by stereo correction and matching. Finally, the 3D information is output by clicking the target on the disparity map, and through physical measurement distance to verify the reliability of the method.
