Abstract
Non-sinusoidal phase error is common in structured light three-dimensional
(3D) shape measurement system, thus we perform theoretical and experimental analyses
of such error. The number of non-sinusoidal waveform errors in a 2π phase period
is the same as the number of steps of the phase-shifting algorithm; no errors occur
within the one-phase period. Based on our findings, a new structured light method,
the linear sinusoidal phase-shifting method (LSPS), that is resistant to
non-sinusoidal phase error is proposed. Experiments show that the non-sinusoidal
waveform error is reduced to an almost negligible level (0.001 rad) using the
proposed LSPS.
