Fringe projection techniques offer fast, noncontact measurements of the surface form of manufactured parts. Fringe projection has seen successful implementation in the automotive, aerospace, and medical industries. Recently, advances in fringe projection have reduced the sensitivity of the measurement system to effects such as multiple surface reflections and projector defocus. Typically, the measurement method is altered to optimize the system for specific measurement conditions, without any regard for quantifying the effects of influence factors. Furthermore, there is no standardized calibration framework for fringe projection systems and uncertainty evaluation of surface measurements is rarely carried out in practice, which places some restrictions on the use of this technique in manufacturing industry.
