Development of Crack Detection System with Unmanned Aerial Vehicles and Digital Image Processing

Conventional crack detecting inspections of structures have been mainly based on visual investigation methods. Huge and tall structures such as cable bridges, highrising towers, dams and industrial power plants are known to have its inaccessible area and limitation in field inspection due to its geometry. In some cases, inspection of critical structural members is not possible due to its spatial constraints. With rapid technical development of unmanned aerial vehicle (UAV), the limitation of conventional visual inspection could be overcome with advanced digital image processing technique. In this study, the crack detecting system using UAV and digital image processing techniques was developed Structure inspection system to detect cracks in structure.
