Asked 3 years, 8 months ago Modified 3 years, 8 months ago Viewed 1k times. Given a pattern image, we can utilize the above information to calculate its Initial solution for planar "objectPoints" needs at least 4 points and uses pose from homography decomposition. Basics This is going to be a small section. Returns the number of inliers that pass the I don’t know how OpenCV handles this ambiguity in the recoverPose () call, or whether this could be the source of your error, but it definitely raises some questions. The optimization method used in OpenCV camera calibration does not include these constraints as the framework does not support the required integer programming and polynomial inequalities. 2 Operating System / Platform => Ubuntu 18. recoverPose是OpenCV中的一个函数，用于从本质矩阵和点对应关系中恢复相机的旋转和平移。该函数的完整语法如下： retval, R, t = cv2.
