To specify a damage in a sewer accurately.SOLUTION: A sewer damage specification device includes: an image acquisition unit 201 for acquiring a first inner surface image of a first sewer; a first flat surface image generation unit 202 for generating a first ceiling development flat surface image and a first bottom part development flat surface image from the first inner surface image; a damage determination unit for determining a damage which is occurring in the first sewer by using the first ceiling development flat surface image and the first bottom part development flat surface image; a model generation unit for generating a learned damage specification model by causing an artificial intelligence to learn the determined damage and the first ceiling development flat surface image and the first bottom part development flat surface image; an image reception unit for receiving a second inner surface image of an inner surface of a second sewer; a second flat surface image generation unit for generating a second ceiling development flat surface image and a second bottom part development flat surface image from the second inner surface image; and a damage specification unit for specifying a damage which is occurring in the second sewer by using the second ceiling development flat surface image, the second bottom part development flat surface image, and the learned damage specification model.SELECTED DRAWING: Figure 2 【課題】精度の高い管渠の損傷の特定を行うこと。【解決手段】管渠損傷特定装置であって、第１管渠の第１内周面画像を取得する画像取得部２０１と、第１内周面画像から第１天井展開平面画像、および、第１底部展開平面画像を生成する第１平面画像生成部２０２と、第１天井展開平面画像および第１底部展開平面画像を用いて、第１管渠に発生している損傷を決定する損傷決定部と、決定された損傷とともに第１天井展開平面画像および第１底部展開平面画像を人工知能に学習させて、学習済み損傷特定モデルを生成するモデル生成部と、第２管渠の内周面を撮像した第２内周面画像を受け付ける画像受付部と、第２内周面画像から第２天井展開平面画像、および、第２底部展開平面画像を生成する第２平面画像生成部と、第２天井展開平面画像、第２底部展開平面画像および学習済み損傷特定モデルを用いて、第２管渠に発生している損傷を特定する損傷特定部と、を備えた。【選択図】図２
