Abstract
We propose a new method of image projection to reproduce similar appearance of real object by using the high luminance DLP (Digital Light Processing) type projector. In this projection, the tristimulus values of image corresponding to the absolute tristimulus values of real object are estimated by combination of the PCA-Spline method and the LUT method. The BRDF (Bi-Directional Reflectance Distribution Function) model is also introduced to fix the geometry between the projector and the viewing location of observer. The result shows that the color difference ΔE*94 between the estimated image and the real object was less than 2.0 and the gloss of the object could be reproduced on the mat paper without any difference of appearance in comparison with the imitated coated paper.
