Abstract: A multiple-wavelength image analysis electro-optical system for detecting a disabled ship and persons overboard of the present invention is a multiple-wavelength image analysis electro-optical system for detecting a disabled ship and persons overboard configured to have an input part 10 provided with an ultra-low light camera 3, a short-wavelength infrared image sensor 5, a medium-wavelength infrared image sensor 7, and a long-wavelength infrared image sensor 9; a signal processing part 20 for receiving and processing data of the input part 10; a display part 30 for receiving and displaying data of the signal processing part 20; a storage part 40 for storing data of the signal processing part 20 and the display part 30; and a control part 90 provided with a camera control board 50 and a drive control board 60 for controlling the input part 10, signal processing part 20, the display part 30 and the storage part 40.

Abstract: A method for detecting a shipwrecked vessel and drown victims by using an aerial hyperspectral image, according to the present invention, comprises the steps of: (a) allowing an image reception unit to receive an observed aerial hyperspectral image, check whether the received aerial hyperspectral image is suitable for detection analysis, and extract observation information, and location information and a reflectance value for each pixel with respect to the detected shipwrecked vessel and drown victims; (b) allowing an image analysis unit to analyze spectral characteristic similarity between a spectral reflection value of a target object and an observed reflection value by using pre-constructed spectral library information and extract constituent materials and an occupation ratio for each pixel of the hyperspectral image, thereby classifying a detection result; and (c) allowing an image visualization unit to display the received hyperspectral image, locations of the detected shipwrecked vessel and drown victim
