WebNov 10, 2012 · Well, I have got a stereo setup where it computes the disparity of stereo image pairs using SGBM (Semi-global block matching), BM (Block matching) and Variational matching algorithm using the OpenCV library. But the disparities are not so good as that of the ground truth disparities. WebThe simpler and not as performing block-matching (BM) algorithm of OpenCV can be invoked in a very similar manner to OpenCV’s SGBM (Section 18.4), with the algorithm name passed to --stereo-algorithm being opencv_bm. It accepts the same parameters except -P1 and -P2, and uses in addition the option: paneles msd https://traffic-sc.com
