WebHomography，即单应性，该函数用于求src_points转换为dst_poinsts的单应性矩阵； 为了理解单应性，必须先引入透视变换的概念；把空间坐标系中的三维物体或对象转变为二维图像表示的过程称为投影变换，根据视点（投影中心）与投影平面之间距离的不同，投影可分为平行投影和透视投影，透视投影即透视变换。 平行投影理论上是不存在的，因为它必须在光 … Web我们注意到，这涉及到RANSAC算法，在OpenCV中，调用findHomography()方法时指定cv2.RANSAC参数。 给定原始图像与目标图像，则相应的单应矩阵可以用OpenCV中的findHomography()方法求得。 # pts_src与pts_dst都是numpy arrays h, status = cv2.findHomography(pts_src, pts_dst, cv2.RANSAC)
