Equidistant fish-eye calibration and rectification by vanishing point extraction

IEEE Trans Pattern Anal Mach Intell. 2010 Dec;32(12):2289-96. doi: 10.1109/TPAMI.2010.159.

Abstract

In this paper, we describe a method to photogrammetrically estimate the intrinsic and extrinsic parameters of fish-eye cameras using the properties of equidistance perspective, particularly vanishing point estimation, with the aim of providing a rectified image for scene viewing applications. The estimated intrinsic parameters are the optical center and the fish-eye lensing parameter, and the extrinsic parameters are the rotations about the world axes relative to the checkerboard calibration diagram.
