S9.1 Self-Calibration of a Stereo Rig without Stereo Correspondence

Abstract: In this paper, we introduce a new self-calibration method for a stereo rig using general rigid motions. Unlike the existing methods, our method does not involve any stereo correspondence. Rather the method requires the computation of camera motion between pairs of monocular images. We show that the computation of the stereo geometry, i.e. the rotation and the translation between the two cameras can be carried out using standard linear algebra tools. We provide a stability study for the method in the presence of noise. Synthetic and real experiments demonstrate the feasibility and robustness of the proposed method. Moreover, the developed method can be used to solve the stereo correspondence problem as well as the 3D shape of the observed scenes using a cooperative stereo-motion framework.
