The Gamma (γ) distortion caused by digital video projector contributes most for phase error in digital fringe projection profilometry. The residue phase error is still non-negligible after γ correction and phase error compensation based on single γ value. By analyzing the non-uniform distribution of γ, a novel phase error compensation technique, which dynamically constructs the phase error look-up-table (LUT) regarding to the γ value of the specific pixel, is introduced and it effectively improves the accuracy of phase error compensation. The measured results are analyzed and compared and it shows that higher accuracy could be achieved with this method.
