This paper describes a method for precisely estimating surface reflection properties of Japanese swords, including surface roughness and reflection model parameters. In order to estimate reflection properties of a Japanese sword, we develop an apparatus for measuring a distribution of light reflection intensity on the Japanese sword. The apparatus consists of a lighting system, a goniometric rotating arm and a vision system. The problem of estimating reflection properties such as reflection model parameters can be solved as the fitting problem of reflection intensity. These model functions with unknown parameters are fitted to the intensity data of reflection distribution acquired at different angles of incidence angle and viewing angle.
