Parameter-Free Lens Distortion Calibration of Central Cameras
In this paper we propose a parameter-free camera model where each imaging ray is constrained to a common optical center forcing the cam- era to be central.
Self-Calibration of a General Radially Symmetric Distortion Model
24 mai 2009 symmetric distortion. In contrast to most current models we propose a model encompassing fisheye lenses as well as catadioptric cameras ...

In this paper we propose a parameter-free camera model where each imaging ray is constrained to a common optical center forcing the cam- era to be central.
An Exact Formula for Calculating Inverse Radial Lens Distortions
7 févr. 2017 When Brown [6] proposed a radial distortion model in 1971 he also proposed a way to calibrate cameras using a set of plumb lines.
