WebYou can try Semi-Global Block matching also to calculate disparity. Here in the numDisparities, you have set it as 16. You need to set it in multiples of 16 in OpenCV, so you need to set the number of disparity to 48. I think you might need to divide the result of disparity by 16 before calculating the depth. – Gopiraj Sep 30, 2024 at 4:26 I see.

WebA block matching algorithm involves dividing the current frame of a video into macroblocks and comparing each of the macroblocks with a corresponding block and its adjacent neighbors in a nearby frame of the video (sometimes just the previous one). A vector is created that models the movement of a macroblock from one location to another. .
