What is stereo camera calibration?
Stereo-rig calibration aims at finding the intrinsic parameters (principle point, distortion parameters and focal length) of each camera and the extrinsic parameters (rotation and translation) defining the relative pose between cameras.
Is camera calibration necessary?
The camera calibration aims to determine the geometric parameters of the image formation process [1]. This is a crucial step in many computer vision applications especially when metric information about the scene is required.
