Camera calibration is the process of estimating the parameters of a camera to correct distortions and achieve accurate image measurements. It involves determining the intrinsic and extrinsic parameters of the camera to map the 3D world onto a 2D image plane accurately.

Intrinsic parameters are the internal characteristics of a camera that affect how images are captured, such as focal length, optical center, and lens distortion. These parameters are crucial for tasks like camera calibration and 3D reconstruction, as they help in accurately mapping the 3D world onto a 2D image plane.

Intrinsic Parameters

Extrinsic parameters are used in computer vision to describe the position and orientation of a camera in relation to a world coordinate system. They are crucial for tasks such as 3D reconstruction and scene understanding, as they allow for the transformation of points from the world coordinate system to the camera coordinate system.
