What is checkerboard 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 calibration matrix?
Calibration is the process of estimating the intrinsic and extrinsic parameters of the camera. It can be thought of as a two stage process: estimating the matrix C, and. estimating the intrinsic and extrinsic parameters from C.
What is camera calibration Opencv?
Camera Calibration is nothing but estimating the parameters of a camera, parameters about the camera are required to determine an accurate relationship between a 3D point in the real world and its corresponding 2D projection (pixel) in the image captured by that calibrated camera.
