Abstract

A phase unwrapping method using the error-controlled fringe projection scheme for phase-shifting projected fringe profilometry is presented. Most unwrapping methods cannot cope with the problems caused by low signal-to-noise ratios. The presenting method can detect such kind of errors and recover the mistake.
