Abstract

The invention discloses an ocean oil spill type fast identification method. The method utilizes a UV source-induced fluorescent light source system, a multi-spectral camera system and an image identification system. The UV source-induced fluorescent light source system comprises UV zone light sources with three wavelengths of 254nm, 302nm and 365nm. The multi-spectral camera system comprises 8 filters installed in front of a common camera. The filters have wavelengths of 365, 404, 410, 420, 435, 450, 546 and 577. The filter camera acquires images. The image identification system carries out oil type identification on image-acquired 6 oil products (comprising gasoline, diesel oil, kerosene, machine oil, crude oil and plant oil) according to acquired image spot RGBHSV color mean value as a characteristic. Oil type identification is carried out by K-mean clustering subjected to PCA optimization and ICA characteristic optimization and SVM identification. The method is economic and simple and can realize fast identification of ocean oil spill types.

Description

technical field [0001] The invention relates to a method for identifying marine oil spilled oil species used in the environmental field, in particular to a method for identifying oil species through ultraviolet light-induced fluorescence multi-spectral imaging. Background technique [0002] In recent years, marine oil spill accidents have occurred frequently. It is a complex and challenging task to analyze and identify the spilled oil in a timely and accurate manner, determine the responsibility, trace the source of illegal oil spills, and take appropriate emergency response. . The current oil spill identification standard (GB / T 21247-2007) is mostly represented by laboratory chemical identification methods represented by phase chromatography / mass spectrometry. Although it can accurately analyze oil species, the detection speed is slow and the cost is high. [0003] In recent years, spectral analysis has become a new method of oil spill identification and has attracted wide...
