Optical monitoring of film pollution on sea surface

The organic films form a brightness contrast on the sea surface. It makes possible to use cheap simple and miniature systems for video monitoring of pollution of coastal marine areas by oil products in the bunkering of ships, emergency situations at oil terminals, gas and oil pipelines, hydrocarbon production platforms on the shelf, etc.1-16 A panoramic video system with a polarization filter on the lens, located at an altitude of 90 m above sea level, can provide effective control of the water area within a radius of 7 kilometers,17-19 and modern photogrammetry technologies allow not only to register the fact of pollution and get a portrait of the offender, but also with a high Spatial and temporal resolution to estimate the dimensions and trace the dynamics of movement and transformation of the film in a geographic coordinate system. Of particular relevance is the optical method of controlling the pollution of the sea surface at the present time with the development of unmanned aerial vehicles that are already equipped with video cameras and require only a minor upgrade of their video system to enhance the contrast of images of organic films.
