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。 This article describes an experiment to monitor the oil spill in the sea using multi-band photography on board. Experiments show that although the spectral reflectance of seawater and oil film is relatively low, there is a large contrast in the 0.3-0.5 micron spectral range, and a clear oil overflow image can be obtained. Experiments also show that the best spectral bands can be obtained from the near-UV region to the red region by choosing the best combination of spectral bands. Among them, the blue-violet spectral region is the most ideal, followed by the near-ultraviolet and blue-green spectral regions, the red-region difference. This experiment provides a better real-time monitoring method for water environment pollution monitoring and scientific research.
