Mirrors in motion: epipolar geometry and motion estimation [PDF]

Proceedings Ninth IEEE International Conference on Computer Vision, 2003
In this paper we consider the images taken from pairs of parabolic catadioptric cameras separated by discrete motions. Despite the nonlinearity of the projection model, the epipolar geometry arising from such a system, like the perspective case, can be encoded in a bilinear form, the catadioptric fundamental matrix.
