WebDec 12, 2024 · The SGBM API can provide you a table relating disparity values to depths (presuming your cameras are calibrated correctly). Let's say your point cloud is a vector of (x,y,z) coordinates. Iterate over the columns and rows of your depth map image (each depth cell in turn). Project a point in the camera's coordinate space to the corresponding ... WebApr 9, 2024 · Good afternoon, I am looking to obtain a good disparity map with the SGBM algorithm to be able to approximate the depth of the objects in the image. The problem is that the disparity map gives me something wrong, since the closest objects appear to me in black, some in the middle in white and in the background black again. my code to get the …
