The Monochrome-Projection Color-Analysis (MPCA) technique is proposed in order to measure the three-dimensional shape of an object having a complicated surface color, to shorten the measurement time and to improve measurement accuracy. An optimal color channel is chosen, and a single channel image for intensity calculation is compounded so that the greatest amount of information from an observation image is used and the effect of object color on the measurement is mitigated. By combining MPCA and the Optimal Intensity-Modulation Projection (OIMP) technique, approximately 100 stripes are reliably detectable in a single pattern projection and double image capture.
