A Separation Method of Superimposed Gratings in Double-Projector Fringe Projection Profilometry Using a Color Camera [PDF]
, 2021 Fringe projection profilometry has been intensively studied for several decades. However, due to the limitation of the field range of a single projector, when measuring objects with complex surfaces, there are always shadow areas in the captured images ...

Fiber-based high-speed fringe projection profilometry [PDF]
Phase shift profilometry has become a standard technique for recording the surface of an object using the projection of sinusoidal patterns. We present a method of projecting the patterns via a pair of single-mode optical fibers mounted within a needle ...
