Description

technical field [0001] The invention relates to the field of signal processing, in particular to a water surface oil spill detection system and method based on ultraviolet images. Background technique [0002] Oil spills are one of the main causes of river and ocean pollution. With the development and utilization of marine resources and the increasing number of water transport vehicles, the environment of rivers and oceans has been seriously damaged, and the living environment of birds, fish and marine plankton that inhabit and live in water bodies has been seriously damaged. influences. [0003] Due to the low cost of water transportation, 90% of my country's imported oil is transported to the country by ships, which increases the density of water transportation. Cargo loading and unloading activities on port terminals have become more and more frequent, making the water environment more and more complex, which in turn increases the chance of oil spills from ships.
