本文描述了一种用于估计物体的表面特性的方法，包括折射率、表面光谱反射率和反射模型参数。使用表面材料的光学参数对物体表面的这些反射特性进行建模。这些参数是从摄像机RGB传感器测量在不同的照明和观看条件下物体表面的反射强度来估计的。为了估计这些参数的反射模型，我们开发了一个装置，用于测量物体表面上的反射强度。通过应用线性有限模型和相机RGB传感器数据来估计光谱反射率。最后，所有的估计被组合用于在不同的照明和观看条件下渲染对象。
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.
