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 partprovided with an ultra-low light camera, a short-wavelength infrared image sensor, a medium-wavelength infrared image sensor, and a long-wavelength infrared image sensor; a signal processing partfor receiving and processing data of the input part; a display partfor receiving and displaying data of the signal processing part; a storage partfor storing data of the signal processing partand the display part; and a control partprovided with a camera control boardand a drive control boardfor controlling the input part, signal processing part, the display partand the storage part

Multiple-wavelength images analysis electro optical system for detection of accident ship and submerged person and analysis method thereof

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 victims, and detailed information of the detection result.
