在本文中，我们提出了一种新的方法来恢复一个近似的双向反射分布函数（BRDF）的表面存在于一个真实的或合成场景。这是从一张照片和场景的3D几何模型完成的。其结果是所有表面的反射特性的完整模型，可以在新的照明条件下进行渲染，例如，视点修改和添加新的合成对象。我们的技术产生一个反射率模型，使用少量的参数。然而，这些参数近似的BRDF，并允许恢复的漫射，镜面反射，各向同性或各向异性纹理对象的光度特性。输入数据是包括光源位置和相机属性的场景的几何模型，以及单个捕获的图像。我们提出了几个合成图像，与原始图像相比，以及在增强现实中的一些可能的应用，如新颖的照明条件和添加合成对象。
In this paper, we present a new method to recover an approximation of the bidirectional reflectance distribution function (BRDF) of the surfaces present in a real or synthetic scene. This is done from a single photograph and a 3D geometric model of the scene. The result is a full model of the reflectance properties of all surfaces, which can be rendered under novel illumination conditions with, for example, viewpoint modification and the addition of new synthetic objects. Our technique produces a reflectance model using a small number of parameters. These parameters nevertheless approximate the BRDF and allow the recovery of the photometric properties of diffuse, specular, isotropic or anisotropic textured objects. The input data are a geometric model of the scene including the light source positions and the camera properties, and a single captured image. We present several synthetic images that are compared to the original ones, and some possible applications in augmented reality such as novel lighting conditions and addition of synthetic objects.
