Crack Detection Using Multiple Image Processing for Unmanned Aerial Monitoring of Concrete Structure

Concrete structures are subjected to crack formation over time. The causes of crack formation are shrinkage, thermal stress, weathering, etc. This paper is about the construction and application of a device that uses image processing to detect cracks. The system is carried by a drone and can be remotely accessed. The system has a graphical user interface for initializing the device, viewing real time video, taking pictures of a crack, measuring its width, and evaluating if safe or unsafe. The pictures and their results are stored for reference.
