Paper Abstract

A method using multiple fringe projections from different viewpoints for finding the absolute shape of an object is proposed. In this method, surfaces with large depth discontinuities can be identified without ambiguity. Shadowing caused by tilted fringe projection can be eliminated as well. The other advantages of the proposed measurement system are: (1) large depth-of-field in the projection system; (2) very low fringe distortion (even for a large field of view); and (3) robust performance to analyze dynamic objects.
