摘要：

A fringe pattern correlator (FPC) for three-dimensional (3D) object recognition is developed using a spatial frequency multiplex color grating (SFMCG) to avoid phase ambiguity problem. The SFMCG consists of multiple color gratings with different carrier frequency. When the SFMCG is projected onto a 3D object, a color deformed grating pattern modulated by 3D shapes is obtained. Using color decomposition techniques, multiple monochromatic deformed grating patterns can be extracted from the color deformed grating pattern. Because the FPC in different sensitivity is easily executed using these monochromatic deformed grating patterns, exact 3D object recognition can be performed.
