Homography shader
WebI have a 3x3 homography matrix that works correctly with OpenCV's warpPerspective, but I need to do the warping on GPU for performance reasons. What is the best approach? I … Web工程实践. If you have more than 4 corresponding points, it is even better. OpenCV will robustly estimate a homography that best fits all corresponding points. Usually, these point correspondences are found automatically by matching features like SIFT or SURF between the images. ''' pts_src and pts_dst are numpy arrays of points in source ...

This has many practical applications, such as image rectification, image registration, or camera motion—rotation and translation—between two images. Once camera resectioning has been done from an estimated homography matrix, this inform…
