本文提出了一种简单实用的从一组图像中恢复表面形状和反射率的三维建模方法。我们将一个点光源附加到手持相机上，为多视点立体问题增加了光度限制。利用光度约束，我们同时求解形状、表面法线和反射率。与之前的方法不同，我们使用近光源、非朗伯曲面、透视相机模型和环境照明的现实假设来制定问题。通过仿真和真实场景验证了该方法的有效性。
This paper presents a simple yet practical 3-D modeling method for recovering surface shape and reflectance from a set of images. We attach a point light source to a hand-held camera to add a photometric constraint to the multi-view stereo problem. Using the photometric constraint, we simultaneously solve for shape, surface normal, and reflectance. Unlike prior approaches, we formulate the problem using realistic assumptions of a near light source, non-Lambertian surfaces, perspective camera model, and the presence of ambient lighting. The effectiveness of the proposed method is verified using simulated and real-world scenes.
