Paper Abstract

3D shape reconstruction using fringe projection or interference schemes has been extended studied. However, speckle noises could be introduced once a coherent light source is used. In this paper, we use the empirical mode decomposition (EMD) to remove speckles caused by such kind of coherent illumination. This makes it possible to accurately analyze fringes in the frequency domain and to accurately reconstruct a 3D image.
