Fringe projection techniques: Whither we are?

Fringe projection profilometry (FPP) has the advantages of non-contact, quick and high accuracy, which is popular in the fields of industrial inspection and measurement. However, the coded fringe patterns may be failure suffered from the high reflectivity of the measured surfaces. Aiming at this problem, an adaptive fringe projection method is proposed in this paper by the best projection intensity strategy and the coordinate mapping...
