Abstract

A method for determining the shape and color of an object simultaneously based on Moire analysis using a reflection model is presented. An RGB color system is employed to represent color information, and the color of an object is determined from the reflectance of RGB planes. Utilizing color consistency and the specular reflection of reflected light, reflectance ambiguity for each RGB plane is reduced when using even a single light source, significantly improving the reliability of shape and reflectance determination for each RGB plane.
