External material inspection system

An object of the present invention is to inspect abnormalities of an outer surface material of a structure in a short time. In an external surface material inspection system for processing an image captured by a flying object and displaying the processed image on a terminal device and investigating the state of the external surface material of a structure, the flying object captures a visible light image. The terminal device 30 or the flying object 10 includes a visible light image and / or a non-visible light image capturing unit that captures a non-visible light image by an electromagnetic wave or a sound wave in a region other than visible light. Image processing means for executing predetermined image processing on the invisible light image, flying object control means for controlling the flight state of the flying object based on the image processing result by the image processing means, and image processing result by the image processing means And an abnormality detecting means for detecting an abnormality of the outer surface material based on the above.
