RECOVERING MULTIPLE VIEW RELATIONS FROM MUTUAL PROJECTIONS OF MULTIPLE CAMERAS

摘要

In this paper, we analyze the computation of epipolar geometry in some special cases where multiple cameras are projected each other in their images. In such cases, epipoles can be obtained directly from images as the projection of cameras. As the result, the epipolar geometry can be computed from less image correspondences with higher stability. In this paper, we analyze the number of corresponding points required for computing bifocal, trifocal and quadrifocal tensors in the case where cameras are projected mutually. We next study the stability of extracted epipolar geometry under mutual projections.
