Why checkerboard pattern for camera calibration?
The checkerboard pattern is the most commonly used calibration pattern for camera calibration. The control points for this pattern are the corners that lie inside the checkerboard. Because corners are extremely small, they are often invariant to perspective and lens distortion.
What is camera calibration Mathworks?
Camera calibration is the process of estimating camera parameters by using images that contain a calibration pattern. The parameters include camera intrinsics, distortion coefficients, and camera extrinsics.
