Modeling reflectance properties from real objects is useful for solving many practical problems, ranging from industrial inspection to computer graphics. In particular, building computer graphics models directly from real objects has recently received increased attention, because it is useful in many important fields such as CAD, entertainment (3-D games, movies) and virtual museums. This paper describes an automatic way to recover actual reflectance parameters, from range and intensity (or color) data acquired from objects. The proposed approach is based on Phong reflection model, since this model is usually preferred for computer graphics.
