デザイン工学部都市環境デザイン工学科の今井龍一教授は、次世代の橋梁維持管理に向けた「統合データモデル」の確立を目指す新たな研究成果を発表しました。本研究は、老朽化する社会インフラの高度な維持管理やDX化に寄与するもので、都市環境デザイン学科が取り組む“持続可能な都市基盤のデザイン”とも深く関連します。今回の英文プレスリリースでは、橋梁点検データの一元化や3次元空間情報を活用した新しい保全モデルの可能性が示され、国内外の共同研究をさらに加速させる内容となっています。
Title: Unified 3D Data Model Enhances Bridge Maintenance through Digital Integration
Caption: A new data model developed by researchers from Hosei University and collaborating institutions integrates IFC and CityGML standards to unify 3D geometry with inspection and repair information. This “one-source, multi-use” framework enables data-driven maintenance, predictive management, and the creation of digital twins for aging bridge infrastructure.
