Development of multi-spectral based reflection model of art objects for 3D digital archives

在这项研究中，我们开发了基于多光谱的三维（3D）数字档案馆的反射模型。通常，难以数字存档艺术对象，因为对象的外观（诸如粗糙或阴影）取决于观看和照明方向而改变。因此，我们开发了一种方法来估计的多光谱反射特性的对象的角度光谱图像测量的基础上，三维数字档案。此外，我们提出了一种方法，用于精确渲染和颜色再现的艺术对象的基础上的多光谱反射模型和估计的反射特性检测成像的对象表面。

In this study, we develop multi-spectral based reflection models for 3 dimensional (3D) digital archives. Generally, it is difficult to digital archive an art object because appearance of the object such as gross or shade is changed depending on viewing and illumination directions. Therefore, we develop a method for estimating the multi-spectral reflection properties of the object based on gonio-spectral image measurements for 3 D digital archives. Moreover, we propose a method for the precise rendering and color re-production of art objects based on a multi-spectral reflection model and the estimated reflection properties detected by imaging the object surface.
