Research on 3D measuring based binocular vision

Auto-Measuring via vision is meaningful to the reconstruction of 3D model. There are many problems to be solved in this area. This article presents a complete flow of 3d measuring system with two CCD cameras, which includes camera calibration, rectification of stereo pair, stereo match and disparity optimization. Introduced the parameters in camera pinhole model, the principle of re-projection in rectification, steps of stereo match and difficulty.
