| Abstract(in English) | It is necessary to acquire the accurate reflectance properties of an object, if we want to use this object as a model for computer vision and graphics applications. However, wrong reflectance parameters are estimated, when interreflection exists. Interreflections are negligible for convex objects, while it is not for concave objects. This paper addresses a method to estimate diffuse reflectance parameters of an outdoor object with the presence of interreflection. This paper solve the problem by assuming that a surface consists of hundreds of small facets. The interreflection effect on a facet is calculated as the sum of incoming light energy from all the other facets. Experimental evaluation on both simulation and real outdoor objects shows the improvement achieved by this method. |
