Abstract

The invention discloses an ultraviolet image based water surface oil spill detection system and method and relates to the field of signal processing. The ultraviolet image based water surface oil spill detection system comprises an ultraviolet imaging module, a video decoding buffer module, an image processing module and an alarm module which are connected in sequence. The ultraviolet imaging module comprises an ultraviolet light source, an ultraviolet bandpass filter and a camera. The video decoding buffer module comprises a video decoding chip and a synchronous dynamic random access memory. The camera is connected to the video decoding chip and the video decoding chip is connected to the synchronous dynamic random access memory. The image processing module comprises a DSP (Digital Signal Processor) chip and a program loading chip. The video decoding chip, the synchronous dynamic random access memory and the program loading chip are all connected to the DSP chip. The alarm module comprises a relay, a sound and light alarm and a wireless data transmitter. The ultraviolet image based water surface oil spill detection system and method is good in water surface oil spill detection effect and high in anti-interference capability.

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.
