This paper describes a method for estimating surface properties of an object, including an index of refraction, surface spectral reflectance, and reflection model parameters. These reflection properties of the object surface are modeled using optical parameters of the surface material. These parameters are estimated from camera RGB sensor measurements for reflection intensity of an object surface at different conditions of illumination and viewing. In order to estimate these parameters of the reflection model, we develop an apparatus for measuring reflection intensity on the object surface. The spectral reflectance is estimated by applying the linear finite model and the camera RGB sensor data. Finally, all estimates are combined for rendering of the object under different illumination and viewing conditions.
