Calibration of fringe projection profilometry: A comparative review

Fringe projection profilometry is widely used for three-dimensional (3D) measurements. System calibration is crucial to fringe projection systems, since it determines how the phase is converted into 3D geometry. Many methods and studies on calibration have been presented in the last few years. However, a comparative overview on the accuracy and the implementation details is still lacking. In this work, we present a review of some of the most...
