A radial distortion model can look like this and 2 are the radial distortion OpenCV cv::undistort(img, undist_img, P, distCoeffs); cv::undistortPoints(pts

A camera calibration technique based on OpenCV - IEEE Xplore

In this paper, the camera model in OpenCV (open source computer vision library) is discussed, the non-linear distortion of the tangential and radial distortion
