WebFisheye Calibration Basics. Camera calibration is the process of computing the extrinsic and intrinsic parameters of a camera. Once you calibrate a camera, you can use the image information to recover 3-D information from 2-D images. You can also undistort images taken with a fisheye camera. The Computer Vision Toolbox™ contains calibration ...
