我们提出了一个新的框架，从一个单一的观点重建均匀，透明，折射高度场。高度场相对于已知的平面背景或背景序列成像。与现有的逐点重建方法不同（已知其具有难以处理的模糊性），我们的方法同时对整个高度场进行估计和优化。该配方支持从测量的失真（偏转）或直接从图像本身，包括从一个单一的图像的形状恢复。我们报告了各种折射高度场的结果，显示出比现有技术的显着改善。
We propose a novel framework for reconstructing homogenous, transparent, refractive height-fields from a single viewpoint. The height-field is imaged against a known planar background, or sequence of backgrounds. Unlike existing approaches that do a point-by-point reconstruction - which is known to have intractable ambiguities - our method estimates and optimizes for the entire height-field at the same time. The formulation supports shape recovery from measured distortions (deflections) or directly from the images themselves, including from a single image. We report results for a variety of refractive height-fields showing significant improvement over prior art.
