An Edge-Preserving Nonlinear Error Suppression Method for Fringe Projection Profilometry Based on Low-Pass Guided Filtering

In fringe projection profilometry, phase accuracy is a key factor in determining the ultimate measurement precision. However, errors stemming from the nonlinear response of the projector and camera are introduced into the phase map, manifesting as periodic artifacts that seriously compromise measure...
