| 摘 要： | 水下相机向上对海洋表面场景成像时会形成扭曲的图像，为了矫正图像并重构场景，提出了一种基于水下对空成像的波面计算方法，通过分析光线在空一水交界面的传输特性，建立了前向散射和消光边界模型，并在消光边界处估计出表面的径向斜率。从而为海浪高度的计算奠定了基础。

| Abstract: | A method for wave suface estimation from the imagery collected by an upward looking was presented, submerged camera for the purpose of reconstructing the above-surface scene. Forward scattering and extinction boundaries model are infeted through analysing the ray prorogation characteristic on air-water interaction surface. Radial surface slope is deduced near extinction boundaries, which ean be used to estimate the surface wave. |
