Abstract
Moire topography method is a well-known non-contacting 3-D measurement method. Recently, the automatic 3-D measurement by moire topography has been required since the method was frequently applied to the engineering and medical fields. The 3-D measurement using projection moire topography is very attractive because of its high measuring speed and high sensitivity. In this paper, using the two-wavelength methods of projection moire topography was tested to a measuring object with 2pi-ambiguity problems. Also, rapid measurement can be accomplished by the synchronization between CCD camera and projector. The experimental results prove that the proposed scheme is capable of finding absolute fringe orders, so that the 2pi-ambiguity problems can be effectively overcome so as to treat large step iscontinuities in measured objects.
