Abstract

Introduction Given a panoramic stereo pair acquired with a hyperbolic mirror, we are interested in establishing a dense correspondence between the given pair. In this section we briey describe what are given, what problems we encounter and what related work appeared in the literatures. In order to have the reected optical rays intersected in the focus of the hyperboloid (i.e. the mirror), the perspective projection of a camera is required. Similarly for a parabolic mirror, the orthographic projection of a camera is required. The details of such a family of the acquisition models can be found in [2, 4]. Since the input images are very distort, it is almost impossible to obtain a good matching result without recovering the epipolar geometry. The epipolar geometry of such an acquisition model has been found out to be conic, i.e. given one point in one image of the pair, the possible locations of its corresponding point in the other image are either lying on a circle, ellipse,
