you can use block-matching, (StereoBM, StereoSGBM), to generate a disparity(depth) image. from there, you can project your image pixels to 3d (e.g. using the Q matrix from the stereoRectify())

there's a sample here

thank you for your suggestion , please can you help me how to run it , it need those arguments [--algorithm=bm|sgbm|hh|sgbm3way] [--blocksize=<block_size>]\n" "[--max-disparity=<max_disparity>] [--scale=scale_factor>] [-i=<intrinsic_filename>] [-e=<extrinsic_filename>]\n" "[--no-display] [-o=<disparity_image>] [-p=<point_cloud_file>]\n"); i have extrinsic, and intrinsic file but what about the other arguments?
