In this study, a PTZ(Pan-Tilt-Zoom) system was developed to analyze the behavior characteristics of pipe fittings and joints using the image processing techniques. In the developed PTZ system, two cameras and lenses were installed in a pan-tilt drive to measure the strain and deformation angle of the piping components using one system. In-plane cyclic loading test was conducted to verify the validity of the method to measure the strain and deformation angle using the developed PTZ system.
