Crack detection on retaining wall by using thermal camera and image processing technique

Monitoring on geotechnical structure such as retaining wall, beams and dams is an essential task to retain its serviceability. One of the necessary component to be monitored is the presence of crack. In this paper, the potential of infrared thermography (IRT) as an operational tool for detecting cra...
