Fluorescence can be a beneficial property not only for the scene analysis, but also for a spatial augmented reality (SAR). In the field of SAR, the projector camera system has been well studied and its radiometric model can be described by a color mixing matrix. For the measurement of the color mixing matrix, special equipments other than a projector and a camera are not required. The fluorescent components are not separated by the color mixing matrix, but it already has a capability of handling light emission of fluorescent. In this paper, we propose the RKS model that expresses fluorescent components as well as reflectance components from the approximation of the Donaldson matrix. In addition, we propose a decomposition method of the color mixing matrix. Experimental results show the decomposition of color mixing matrices obtained from color construction papers and non-fluorescent Kent papers with several fluorescent paintings. Then, we demonstrate separation of reflectance and fluorescent components of a scene. We also demonstrate effectiveness of radiometric compensation that considers fluorescent components.
