Camera resectioning
Camera resectioning (often called camera calibration) is used in Computer Vision and especially in Augmented reality.
In Computer Vision, camera resectioning consists in estimating the camera projection matrix from corresponding 3D world and image entities. See Hartley & Zisserman Chapter 7. The camera projection matrix are also known as the intrinsic and extrinsic parameters of the camera, and are often represented by the combination of three transforms; a matrix of camera intrinsic parameters, a 3x3 rotation matrix, and a translation vector. The camera projection matrix is used to refer points in a camera's image space, into 3D world space.
