Abstract

The paper describes a new method of self-calibration of a moving vision platform (a rig) when the cameras' centers relative to each other during the motion have been determined. Given the projective structure from the corresponding points across the set of images acquired by the cameras, the varying internal and external parameters can be computed using only the positions of the cameras ' centers. The method in this paper shows that the maximal generality is reached when the rig consists of 5 cameras whose centers of projection are given. Furthermore, if the only goal is to construct the Euclidean structure from a projective structure, the internal and external parameters need not be computed, and the process is linear and hence it is more convenient and stable.
