Set up binocular parallel system to measure the distance of the object.It takes four steps of image acquisition,camera calibration,stereo correction and stereo match to obtain that disparity map of the object to be tested,so as to obtain the three-dimensional coordinates of the object to be measured.Using two matching algorithms to make stereo matching,and in oeder to make the result contrast obvious,the color parallax image is outputted on the basis of the previous black and white parallax images.At the same time,in order to improve the matching accuracy,a comparison experiment of denoising a...
