網頁The function computes a decomposition of a projection matrix into a calibration and a rotation matrix and the position of a camera. It optionally returns three rotation matrices, one for each axis, and three Euler angles that could be used in OpenGL. The function is based on RQDecomp3x3 () . 網頁2024年10月30日 · This means that both the images should be aligned, in any possible direction, as if they are stitched together. So, OpenCV's stereoRectification should do the same. The only reason where there is a possibility of stereo rectification not working properly is there are bugs in the code or your calibration phase is wrong. – Sri Raghu Malireddi.
