Abstract

The present paper describes an experimental apparatus and set of calculations for determining various parameters of the surface reflection model. The apparatus consists of a lighting system to emit parallel beams, a goniometric rotating table, and a vision system with six spectral channels. The camera data are used to estimate various parameters such as (1) spectral reflectance, (2) illuminant spectrum, (3) surface roughness, (4) ratio of body to interface intensity, and (5) index of refraction. First, a method for estimating (1)-(4) from a single multband image is introduced. Second, the parameter (5) is estimated using highlight peaks of an object surface at different conditions of illumination and viewing. Experimental results are shown using the curved surface of a painted object. The overall feasibility of our method is confirmed on computer graphics images created by using the estimated parameters.
