Research output: Chapter in Book/Report/Conference proceedingConference contribution


Many infrastructures are conducting smart inspections using drones and various inspection equipment. Bridge inspections are still mostly performed by manpower, and the demand for unmanned equipment-based inspections to improve these traditional methods is increasing. In this research, a drone was used to photograph the entire view of the bridge, and rail, wire-cam were used to check the inspection blind spots that occur during inspection by personnel. A 360-degree camera was used in the part accessible to the inspector. Based on the images obtained through all technologies, a three-dimensional road view of the inspection bridge was constructed. The image-based inspection result is intuitive for both managers and inspectors, so it will improve convenience and efficiency during maintenance.
