Automated center of radial distortion estimation, using active targets

Abstract

In this paper an automated center of radial distortion estimation algorithm is explained. The method applied to the development of an autonomous camera calibration algorithm. The idea of active targets, which are controlled by calibration algorithm is the key to the autonomy in this work. The proposed method decouples the center of radial distortion from other calibration parameters. It is shown that the proposed method approximates the center of radial distortion correctly. Also it helps to the accuracy of calibration framework. © Springer-Verlag 2010.
