Abstract
Camera calibration which is also described as camera re-sectioning, involves approximation of various parameters between the lens and the image sensor of a camera. These variables serve different purposes, which include removal of lens distorsion, estimating the distance between the image and the lens which in turn aids to locate the camera position, or determine the size of an object. The pinhole camera model focuses on the linear mapping of world co-ordinates with image co-ordinates. This project aims to shed light on the significance of non-linear relation between the two-dimensional (2D) image plane and the three-dimensional (3D) object.
