Abstract

In this paper we present a review of the phase unwrapping problem in Fringe Pattern Profilometry (FPP), based on which we study the spatial shift wrapping problem in spatial shift estimation (SEE) based FPP. An approach for carrying out the spatial shift unwrapping is proposed with its performance confirmed by experiments.
