Calibrate fisheye lens using OpenCV — part 1 by Jiang Medium
It connects a point gray camera with lan. Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from the symmetry of a photographic lens. However, the rectified image is still a bit distorted (see images below). Now the fun part — write some code.
