An elliptical function model for fisheye camera correction

Abstract

An elliptical function to model the nonlinear relation between 3D incoming rays and corresponding fisheye image coordinates is presented in this paper. Image coordinates are firstly lifted from a 2D plane to a five-dimensional quadratic space. And then the elliptical function model is built to use a linear combination of the distorted parameters of fisheye… (More)
