| Outline of Final Research Achievements |
In this study, as an actual application of the multi-primary image projector constructed in our previous study, we developed a new measurement method for the reflectance characteristics on the object surface. Then we conducted an appearance editing of real objects by superimposing projection on the object surface using the multi-primary image projector. Specifically, the following items were performed: (1) construction of a multi-primary image projector - camera system, (2) construction of a method for measuring fluorescent objects, structural color objects, and reflection characteristics of human skin by spatially-modulated and wavelength-modulated projection, and (3) construction of appearance editing method for those three types of objects.
