Abstract

A scanning fringe projection technique is presented to retrieve the 3D shape of an object with large depth discontinuities. Shadowing caused by tilted fringe projection can be eliminated. With a reliable image processing algorithm, noises and errors for surfaces on the edge area are efficiently detected and reduced.
