Binocular stereoscopic vision technology is a significant research field of computer vision, and its application is becoming more and more extensive, especially in precision measurement field. The core part of the stereo vision is stereo matching. This paper analyzes the main methods and the key algorithms of matching technology from the perspective of stereo matching technology. Based on the primitive matching algorithm, this paper looks forward to the development trend of the technology. By comparing the advantages and disadvantages of each algorithm, we can get a better understanding of the matching technology and provide the theoretical basis for the future application of binocular vision measurement.
