Development of a Bridge Inspection Support Robot System Using Two-Wheeled Multicopters

摘要

We developed a bridge inspection support robot system that uses a two-wheeled multicopter and 3D modeling technology. Our system is divided into three main parts: 1) a two-wheeled multicopter to capture close-up images of the inspection target, 2) damage extraction using 3D modeling technology, and 3) a 3D model-based bridge maintenance system that stores inspection information linked with the Industry Foundation Classes (IFC) 3D product model. An inspector can use this system to visually inspect the overall structure and accurately detect hairline cracks.
