Goal In this section, • We will learn about distortions in camera, intrinsic and extrinsic parameters of camera etc. • We will learn to find these parameters, undistort images etc. Basics Today's cheap pinhole cameras introduces a lot of distortion to images. Two major distortions are radial distortion and tangential distortion. Due to radial distortion, straight lines will appear curved. Its effect is more as we move away from the center of image. For example, one image is shown below, where two edges of a chess board are marked with red lines.
