Abstract:The nonlinearity effect in the system of fringe projection profilometry (FPP) will cause the non-sinusoidal deviation of the fringe patterns, inducing ripple-like phase errors and further affecting the measurement accuracy. This paper presents an online nonlinearity elimination method based on slope intensity coding. Two sequences of sinusoidal phase-shifting fringe patterns with different frequencies, and one slope intensity pattern with one uniform intensity pattern are projected. The equations of the nonlin… Show more
