WebFeb 4, 2015 · 8tree has developed a 3D fringe projection system that uses a digital light projector to project fringe patterns onto a part, calculate 3D data and project the results … WebFringe projection profilometry (FPP) is a spatial coding technology that uses a projector to project a series of sinusoidal fringe patterns onto the surface of the measured object. A camera captures the deformed fringe patterns modulated by the surface of the measured object, and then reconstructs the 3D morphology of the measured object [ 1 ].
