To solve the problem that it is necessary to more precisely determine whether a travel path where a moving body such as a vehicle travels deteriorates when diagnosing deterioration of the travel path.SOLUTION: A deterioration diagnostic device comprises: photographic image acquisition means which acquires a photographic image from a photographic device provided on a moving body traveling on a road surface and photographing the road surface; photographic image extraction means which extracts a photographic image taken in the night with the road surface illuminated from the acquired photographic image; and deterioration diagnostic means which uses the extracted photographic image to diagnose whether the road surface deteriorates.SELECTED DRAWING: Figure 1

    【課題】車両等の移動体の走行する走行路の劣化診断においては、さらに精度良く劣化の有無を判定する必要がある。【解決手段】劣化診断装置は、路面を走行する移動体に設けられ前記路面を撮影する撮影装置から、撮影画像を取得する撮影画像取得手段と、前記取得された撮影画像から、夜間に撮影され、かつ、前記路面に対して照明が当たっている状況で撮影された撮影画像を抽出する撮影画像抽出手段と、前記抽出された撮影画像を用いて前記路面が劣化しているか診断する劣化診断手段と、を備える。【選択図】図1
