Abstract: 本文では,橋梁やトンネル等の道路構造物の維持管理の効率化を目的として,構造物の点検時に確認された変状に対し,類似する過去の点検データを検索可能とする手法を提案する.提案手法では,熟練技術者の判定に基づいた距離計量学習を導入することで,点検データ間の距離を新たに定義し,高精度な類似点検データの検索を可能とする.提案手法により提示される過去の類似事例を参考として変状の評価を行うことで,評価業務の効率化および技術者の経験の違いによって生じる評価の差を軽減することが期待できる.本文の最後では,実際のデータを用いた実験を行い,その有効性を確認する.
This paper presents a retrieval method of similar inspection records based on experienced inspectors' evaluation in order to realize more efficient maintenance inspection for road structures such as bridges and tunnels. The proposed method introduces distance metric learning based on experienced inspectors' evaluation, and enables calculation of distances suitable for the retrieval of inspection records. Furthermore, the proposed method performs rank-level fusion that can successfully integrate retrieval results obtained from different aspects, i.e., image and text information. Consequently, inspectors can evaluate distresses referring to past similar records by our retrieval method. Therefore, since it is possible to reduce the differences of evaluation between inspectors for distress assessment, more efficient and accurate maintenance inspection becomes feasible. The effectiveness of the proposed method is verified by several experiments with actual inspection records.
