Method for detecting shipwrecked vessel and drown victims by using aerial hyperspectral image

A detection method for disabled ships and persons overboard based on airborne hyperspectral images comprising,

• (a) receiving an observed airborne hyperspectral image and confirming whether the airborne hyperspectral image is suitable for detection analysis, and extracting observation information, location information and reflectivity value of each pixel of a detected disabled ship and overboard persons, via an image receiving unit;
• (b) analyzing a degree of similarity of spectral characteristics between spectral reflectivity value of a target material and an observed reflectivity value using pre-constructed spectral library information, and extracting a constituent material and occupation ratio for each pixel of the hyperspectral image to classify detected results via an image analyzing unit;
• and
• (c) displaying the received hyperspectral image, location of the detected disabled ship and persons overboard in real-time in image form, and displaying detailed information of the detected results in real-time in text form, via an image visualization unit;
• wherein if the extracted constituent material within each pixel is multi-mixed, a spectral characteristic curve that is completed based on the hyperspectral image is used to extract the constituent material and occupation ratio of each pixel which enables detection in pixel units or less.
