多波段摄影监测海面油溢的实验

本文介绍了用船载多波段摄影对海面油溢进行监测的实验。实验表明,海水与油膜的光谱反射虽然较低,但在0.3—0.5微米光谱区却有较大的对比度,可获取清晰的油溢图像。实验还表明,选择最佳光谱段组合,从光谱近紫外区到红区均能获取海面油溢图像,其中以紫蓝光谱区最为理想,近紫外区和蓝绿光谱区次之,红区较差。 本实验为水面环境污染监测和科学研究提供了一种较好的实时监测手段。

Multispectral Photography Applied to Detecting Sea Oil Spill

This paper discusses the sea oil spill detection using multispectral photographic technique. The experiment shows although sea water and oil spill have low spectral reflection values, but in 300 to 500 nm spectral region, they have larger contrast. It is possible to get good oil spill images in that spectral region. The experiment also shows that it is possible to get oil spill imaging from near ultra-violet to red spectral region with optimal spectral band selecting, but the violet-blue region is a best band, then blue-green, and the red region is poor for oil spill imaging. The results show that this technique could be used for detecting sea oil spill and sea environment pollution.
