Abstract

A technique for calibrating stereo cameras to determine their relative rotations and translations without using absolute position information from external world reference points is proposed. The main idea is to calculate these rotations and translations using a single camera calibration method through a virtual world coordinate system. In this way the stereo camera calibration can be carried out using three reference points of known relative positions on the plane formed by the three points. In addition, we decompose the calibration equations into two groups. The first involves only relative rotational parameters, while the second deals only with translational parameters which can be solved analytically once the rotational parameters have been found. Extensive numerical simulations have shown that the proposed calibration technique is very robust.
