本文讨论了透明物体表面形状的重建问题。这个问题的困难来自于透明物体的视点依赖性外观，这很快使得为漫射表面定制的重建方法失败。本文提出了一种基于光折射的固定视点透明物体稠密曲面重建方法。我们介绍了一个简单的设置，使我们能够改变入射光路之前，光线进入的对象，并开发了一种方法，用于恢复物体表面的基础上重建和三角测量这样的入射光路。我们提出的方法不需要模拟光在物体中传播时的复杂相互作用，也不需要假设物体形状的任何参数形式，也不需要假设沿着光路沿着发生的折射和反射的确切数量。因此，它可以处理具有复杂形状和结构的透明物体，具有未知甚至不均匀的折射率。实验结果的合成和真实的数据证明了我们所提出的方法的可行性和准确性。
This paper addresses the problem of reconstructing the surface shape of transparent objects. The difficulty of this problem originates from the viewpoint dependent appearance of a transparent object, which quickly makes reconstruction methods tailored for diffuse surfaces fail disgracefully. In this paper, we develop a fixed viewpoint approach for dense surface reconstruction of transparent objects based on refraction of light. We introduce a simple setup that allows us alter the incident light paths before light rays enter the object, and develop a method for recovering the object surface based on reconstructing and triangulating such incident light paths. Our proposed approach does not need to model the complex interactions of light as it travels through the object, neither does it assume any parametric form for the shape of the object nor the exact number of refractions and reflections taken place along the light paths. It can therefore handle transparent objects with a complex shape and structure, with unknown and even inhomogeneous refractive index. Experimental results on both synthetic and real data are presented which demonstrate the feasibility and accuracy of our proposed approach.
