Abstract
An apparatus for identifying a warship receives a warship image, estimates a photographing angle and a photographing altitude of the warship from the real warship image, generates virtual warship images from stored virtual warship models based on the estimated photographing angle and photographing altitude, generates virtual warship part images in which main parts are classified and displayed for each of the virtual warship images, generates a part segmentation image in which main parts are classified and displayed for the real warship image, and outputs a type and class identification result of the warship by calculating similarity between each virtual warship part image and the part segmentation image.
