What is intrinsic and extrinsic parameters?

The extrinsic parameters represent a rigid transformation from 3-D world coordinate system to the 3-D camera's coordinate system. The intrinsic parameters represent a projective transformation from the 3-D camera's coordinates into the 2-D image coordinates.

What is extrinsic camera calibration?

Extrinsic calibration aims to obtain the extrinsic parameters that define the rigid relationship, that is, the rotation matrix and translation vector between two coordinate systems.

What is intrinsic camera calibration?

Camera calibration (also known as camera resectioning) is the process of estimating intrinsic and/or extrinsic parameters. Intrinsic parameters deal with the camera's internal characteristics, such as, its focal length, skew, distortion, and image center.
