This increased accuracy requires a new methodology for evaluating distortion models. The object of this paper is to investigate the validity of distortion models at the light of precision re-quirements increased by two or three orders of magnitude.

In this paper, a new model of camera lens distortion is presented, according to which lens distortion is governed by the. 1 Motivations Camera calibration is a necessary step in 3D computer vision in order to extract metric information from 2D images. Lens distortion is one of the main factors affecting camera calibration. In this paper, a new model of camera lens distortion is presented, according to which lens distortion is governed by the coefficients of radial distortion and a transform from ideal image plane to real sensor array plane.
