Multi-scale Template Matching using Python and OpenCV

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.
