Study on Spectral Color Reproduction Based on Ordinary Lighting Environment

Abstract

This paper proposes a method to reconstruct the surface spectral reflectance based on conventional lighting environment even without knowing the light source spectral power distribution and the spectral sensitivity of the camera. In our method, we shoot two ordinary light color samples in office environment and finally reconstruct the surface spectral reflectance by using the mechanism of basis vector and polynomial model. The imaging quality was evaluated by the mean square error and color difference. Analyzing the single light source and dual light source model, the experimental results show that the dual light source model can effectively improve the accuracy of spectral reconstruction.
