Abstract : This paper presents a perspective imaging model that can be used to represent any single viewpoint imaging system. Our imaging model consists of an optical center, whose position is well determined in the 3D space, and a virtual screen on which undistorted images taken with the uncalibrated camera are displayed. This model uses two screens as virtual image planes, and the optical center is estimated as the converging point of those rays that are passing through the corresponding points on these planes. This method has the advantages that 1) it can be applied to any single viewpoint camera, and 2) it can remove any type of distortions. In the experiments, results for normal and omni-directional cameras demonstrate the effectiveness of our method.
