TLDR
A new class of rational radial distortion models with easy analytical undistortion formulae is presented, and experimental results are presented to show that with this class ofrational radial distortion model, satisfactory and comparable accuracy is achieved.Abstract:
The common approach to radial distortion is by the means of polynomial approximation, which introduces distortion-specific parameters into the camera model and requires estimation of these distortion parameters. The task of estimating radial distortion is to find a radial distortion model that allows easy undistortion as well as satisfactory accuracy. This paper presents a new class of rational radial distortion models with easy analytical undistortion formulae. Experimental results are presented to show that with this class of rational radial distortion models, satisfactory and comparable accuracy is achieved.read more

Correcting radial distortion by circle fitting
Rickard Strand,Eric Hayman +1 more
TL;DR: This paper revisits the problem using the division model to parameterise the lens distortion, and demonstrates that the locus of distorted points from a straight line is a circular arc, which allows distortion estimation to be reformulated as circle-fitting for which many algorithms are available.

A Family of Simplified Geometric Distortion Models for Camera Calibration
TL;DR: A simplified geometrical distortion modeling method by using two different radial distortion functions in the two image axes is proposed and the proposed geometric modeling method is more appropriate for cameras whose distortion is not perfectly radially symmetric around the center of distortion.
