INSPECTION SYSTEM AND MANAGEMENT SERVER, PROGRAM, AND CRACK INFORMATION PROVIDING METHOD
To provide an inspection system and a management server using an unmanned flying object suitable for inspection of a concrete revetment.SOLUTION: In an inspection system, a management server comprises: a leaning model storage unit that stores a specialized crack learning model that can specify a specific type of cracks appearing in a concrete revetment, and a non-specialized learning model that can specify a plurality of types of cracks other than the specific type of cracks; a statistical information storage unit that stores a range in which the specific type of cracks frequently appear as statistical information; a range-to-be-detected setting unit that sets, in a photographic image obtained by an unmanned flying object, different ranges to be detected based on the statistical information as ranges to be detected to which the specialized learning model and the non-specialized learning model are applied; a crack information output unit that outputs first crack information and second crack information obtained by applying the specialized learning model and the non-specialized learning model to the ranges to be detected, respectively; and a detection result output unit that outputs detection result information including the first crack information and the second crack information.SELECTED DRAWING: Figure 6
【課題】コンクリート護岸の点検に適した無人飛行体による点検システム及び管理サーバを提供する。【解決手段】点検システムにおいて、管理サーバは、コンクリート護岸に出現する特定種のヒビ割れを特定可能な特化ヒビ割れ学習モデルと、特定種以外のヒビ割れである複数種のヒビ割れを特定可能な非特化学習モデルとを記憶する学習モデル記憶部と、特定種のヒビ割れの出現頻度が高い範囲を統計情報として記憶する統計情報記憶部と、無人飛行体による撮影画像において、特化学習モデル及び非特化学習モデルを適用する検出対象範囲として統計情報に基づいて異なる検出対象範囲を設定する検出対象範囲設定部と、各検出対象範囲に特化学習モデル及び非特化学習モデルをそれぞれ適用して得られる第１及び第のヒビ割れ情報を出力するヒビ割れ情報出力部と、第１及び第２のヒビ割れ情報を含む検出結果情報を出力する検出結果出力部と、を備える。【選択図】図６
