Camera Calibration in OpenCV - How to use OpenCV
https://www.opencvhelp.org/tutorials/advanced/camera-calibration/
WEBCamera calibration is the process of estimating the intrinsic and extrinsic parameters of a camera. These parameters help us model the relationship between a 3D point in the real world and its 2D projection in the image. By calibrating the camera, we can correct distortions and obtain more accurate measurements from images.
