摘要：

In this paper a strategy for 3D object Digitalization, using a pre-filtering and post-filtering stages where the pre-filtering is carried out by the Windowed Fourier Filtering and the post-filtering it is done by a least square algorithm is proposed. The objective of the pre-filtering and post-filtering is to obtain a phase unwrapping with less non-smooth 3D object zones, which is a critical part in the Modified Fourier Transform Profilometry. Phase unwrapping is a fundamental step due to the fact that the object's height (depth information) is present in the wrapped phase. In most of the previous work, where the phase unwrapping results are analyzed, it is possible to detect many zones of non-smooth 3D object. (C) 2012 Published by Elsevier Ltd.
