Abstract

This paper concerns the determination of structure and pose of 3-D bilateral symmetric objects from a single perspective view. A novel algebraic algorithm is described. The unknown structure and pose parameters are determined in three steps. The algorithm first recovers the three rotation angles, then the three translation parameters, and finally the object shape. Computation at all steps is linear and in closed- form. The determination of the rotation angles requires no knowledge about the size of the object, whereas the translation and shape can only be recovered up to a global scale without a priori knowledge of the object dimension.
