3D reconstruction of surface by means of modified temporal unwrapping

The reconstruction of the object surface with inherently discontinuous regions is usually a difficult problem by using standard phase unwrapping technique i.e. the spatial unwrapping. To recover the range data of such a surface, Huntley and Saldner recently proposed a temporal phase unwrapping procedure (TPUP) and Peng X. et al. based on their work proposed an enhanced recursive scheme for the TPUP. However the phase jumps no necessarily they correspond to multiples of 2pi exactly. Due to this, an enhanced scheme for temporal unwrapping in order to increase its efficiency is introduced. Additionally, we present some results obtained by mean of temporal unwrapping and spatial unwrapping, in order to compare them and to demonstrate the effectiveness of the temporal unwrapping.
