Intensity-Averaged Double Three-Step Phase-Shifting Algorithm with Color-Encoded Fringe Projection
Fringe projection profilometry (FPP) has been broadly employed for three-dimensional shape measurements. However, the measurement accuracy suffers from gamma nonlinearity. This paper proposes an intensity-averaged double three-step phase-shifting (IDTP) algorithm making use of color-encoded fringe p...
