| titleOfInvention | Method for automatically identifying sea-surface oil spill in aviation hyperspectral remote sensing mode based on spectral characteristic difference of oil and water |
| abstract | The invention discloses a method for automatically identifying sea-surface oil spill in an aviation hyperspectral remote sensing mode based on the spectral characteristic difference of oil and water. The method comprises the following steps of: 1) calculating the normalization apparent reflectance of each image element of an aviation hyperspectral remote sensing image; 2) calculating oil film indexes of each image element of a normalization apparent reflectance image; 3) constructing an oil film index gradient image and an oil film index gradient angle image on the basis of an oil film index image; 4) performing non-maxima suppression on an edge gradient value; 5) forming an oil film edge image by using the oil film index gradient image which is subjected to the non-maxima suppression; 6) identifying a thin oil film of each image element of the oil film index image to form a thin oil film distribution image; and 7) extracting a sea-surface oil spill total-distribution remote sensing image on the basis of the oil film edge image and the thin oil film distribution image. By adoption of the method, the sea-surface oil spill can be automatically identified in the aviation hyperspectral remote sensing mode. The method can be used for guiding the clean-up evaluation of sea oil spill and plays an important role in sea environment protection. |
