Abstract
In a crack detection device (), an image acquisition unit () acquires image data acquired by taking an image of a road surface from an oblique direction with respect to the road surface. An image classification unit () classifies image data acquired into an acceptable range with a resolution higher than a standard value, and an unacceptable range with a resolution equal to or less than the standard value. A data output unit () outputs acceptable data being image data of a part classified into the acceptable range as data to detect a crack on the road surface. An image display unit () displays data output.
