Spatial-temporal phase unwrapping algorithm for fringe projection profilometry
Optics Express, 2021 In this paper, a generalized spatial-temporal phase unwrapping algorithm (STPUA) is proposed for extracting the absolute phase of the isolated objects with intricate surfaces. This proposed algorithm can eliminate thoroughly the order jumps of various temporal phase unwrapping algorithms (TPUAs), while inheriting the high measuring accuracy of quality ...

Unifying temporal phase unwrapping framework using deep learning
Optics Express, 2023 Temporal phase unwrapping (TPU) is significant for recovering an unambiguous phase of discontinuous surfaces or spatially isolated objects in fringe projection profilometry. Generally, temporal phase unwrapping algorithms can be classified into three groups: the multi-frequency (hierarchical) approach, the multi-wavelength (heterodyne) approach, and ...

Temporally-Consistent Phase Unwrapping for a Stereo-Assisted Structured Light System [PDF]
2011 International Conference on 3D Imaging, Modeling, Processing, Visualization and Transmission, 2011 Phase shifted sinusoidal projection patterns are extensively used in structured light systems due to their low decoding complexity and projection of only three frames per reconstruction. However, they require correct unwrapping of phase images to reconstruct depth accurately.
