| 摘 要： | 由于水中光传输的特殊性,特别是水对光的反向散射,使得水下摄影的成象质量大大低于陆地摄影成象质量。本文从衬度的角度出发,着重讨论了水下摄影中反向散射对成象质量的影响,并比较了不同照明方式对摄影结果清晰度的影响,从而得出窄光束光源照明对提高摄影图像的衬度是大有好处的结果。 本文提供了一些理论分析和初步的实验结果。

| Abstract: | This paper emphatically studies the underwater photographic image quality affected by hack-scattering and its change in different lighting way. This paper obtaines the conclusion that using the narrow beam light of special geometric arrangement lighting is good for improving photographic contrast. It also gives some theory analysis and experimental results. |
