ABSTRACT: A binocular stereo vision measurement technology based on coding structured light method
has been proposed, which will project gray-code fringe patterns and phase-shifting projection gratings onto the
surface of mechanical parts. Three-dimensional coordinates of points can be obtained through gray-code and
phase decoding. In stereo vision measurement, non-sinusoidal phase-shifting gratings influence the precision ...
