Self-indexing of multiview fringe systems

The algorithm proposed in this paper enables the registration of two three-dimensional surfaces of an object when recording with a fringe-projection technique from two different viewpoints. Based on the redundancy and a distance minimization between the views, it leads iteratively to the absolute positioning of the surfaces without fringe coding. The robustness of the algorithm is demonstrated on natural shapes reconstructed from a four-head system. OCIS codes: 100.3010, 110.6880.
