“…The intensity values (i.e. 1 I , 2 I ,  , N I , inv I 1 , inv I 2 ,  , inv N I ) of 2N frame images at the same pixel position are obtained from regular and inverted fringe patterns. Saturated intensity values are removed, and the remaining all unsaturated intensity values are employed to determine the phase by generalized phase-shifting algorithm.…”

“…Phase measurement profilometry (PMP) based on the fringe projection is a well-developed technique and powerful tool in three-dimensional shape measurement for its superiorities of full-filed, high resolution and accuracy [1][2][3][4][5] . However, it is still a big challenging problem to measure objects with a large range of reflectivity variation across the surface.…”

“…Nevertheless, high-precision 3D reconstruction using only one single pattern is a considerable challenge and has been the ultimate goal of structured light 3D imaging in perpetual pursuit. Inspired by the successful application of deep learning in FPP [12][13][14][15][16][17] and different composite fringe coding strategies for spatial frequency multiplexing [18][19][20][21] (Fig. 1(a-d)), we presented a deep learning-enabled single-shot fringe projection profilometry with composite coding strategy, which constructs a deep neural network to analyze a single-shot spatial frequency multiplexing fringe pattern (Fig.…”

“…Then, a modulation ratio would be obtained from the two modulations, which were extracted from a single-shot captured image by Fourier fringe analysis [ 11 ]. Later, Lu et al [ 12 ] used a combined orthogonal grating and produced two different focused image planes by a cylinder lens. Xu et al [ 4 ] used phase error as a quantitative criterion to build the implicit relationship between the height and the defocusing degree.…”
