WebApr 7, 2024 · Fringe projection profilometry (FPP) has been broadly applied in three-dimensional (3D) measurements, but the existing multi-shot methods, which mostly utilize phase-shifting techniques, are heavily affected by the disturbance of vibration and cannot be used in dynamic scenes. In this work, a single-shot 3D measurement method using a … WebMay 10, 2004 · Digital fringe projection profilometry utilizes a digital video projector as a structured light source and thus gains great flexibility.
