描述了一种用于从观察到的图案的表观运动重建诸如水的非刚性透明对象的表面形状的算法。该算法基于对图像失真的光学和统计分析。它包括以下几个部分：光流的提取、从光流序列得到的每个点的轨迹的平均、利用光学特性计算表面法线以及表面重建。将该算法应用于合成图像和真实图像，验证了算法的性能。
An algorithm is described for reconstructing the surface shape of a nonrigid transparent object, such as water, from the apparent motion of the observed pattern. This algorithm is based on the optical and statistical analysis of the distortions. It consists of the following parts: extraction of optical flow, averaging of each point trajectory obtained from the optical flow sequence, calculation of the surface normal using optical characteristics, and reconstruction of the surface. The algorithm is applied to synthetic and real images to demonstrate its performance.<<ETX>>
