Bridge Inspection And Condition Assessment Using Image-Based Technologies With Uavs

Abstract

This paper presents the capabilities and limitations of high-definition (HD) imaging and infrared thermography (IRT) using unmanned aerial vehicles (UAVs) for bridge inspections. Regarding HD imaging, this study shows the potential to detect the required minimum, 0.1 mm, width of cracks using simulated cracks at a distance of 1-3 m from the bridge. As for IRT application with UAVs, the effect of vibration caused by the drone was investigated. This paper concludes that the hovering flight of drones was extremely stable and IRT with UAVs can provide reliable data for bridge inspections. If IRT is used without hovering flight, the effect of flying speed must be investigated since it might also affect the IRT results. This paper shows great potential of image-based technologies with UAVs for bridge inspections without any traffic disturbance as a complimentary approach to current practices.
