Warpperspective vs warpaffine.
Warpperspective vs warpaffine warpAffine(image,M,(cols,rows)) The functions warpAffine and warpPerspective don’t necessarily need to be two distinct functions. In the case when the user specifies the forward mapping: , the OpenCV functions first compute the corresponding inverse mapping: and then use the above formula. getAffineTransform()生成变换矩阵，接下来再用cv2. In OpenCV, the perspective transformation is carried through the cv. warpAffine 函数会取一个2x3 的 变换矩阵 而cv2. warpPerspective(img, M, (cols, rows)) cv2. warpPerspective，你可以使用它们进行各种转换。 Jan 28, 2023 · 文章浏览阅读2.
