Blind Crosstalk Correction for Color Fringe Projection Profilometry Combining the Sine and Cosine Phase-Shifting Patterns

Figure 7

The 500th cross sections. (a–c) Cosine fringes with periods of 18, 144, and 1152 pixels before fringe normalization, respectively; (d–f) sine fringes with periods of 18, 144, and 1152 pixels before fringe normalization, respectively; (g–i) cosine fringes with periods of 18, 144, and 1152 pixels after fringe normalization, respectively; (j–l) sine fringes with periods of 18, 144, and 1152 pixels after fringe normalization, respectively.
