[VI-146] Structural monitoring system of flaking and peeling based on motion-blur compensation in high-speed transition
Keywords:Infrared thermography method, Motion-blur compensation, Galvanometer mirror, Structual health monitoring, Active sensing
The exposure time of thermography camera is invariant due to calibration before actual imaging for the correspondence between sensing data and temperature. Hence, imaging under high-speed transition occurs motion blur in captured images, and fine deterioration becomes blurry due to the decrease of spatial resolution. In this research, we implement motion-blur compensation system with rotation of galvanometer mirror, and aimed to capture still-image-like imaging. Transition experiment at 40 km/h in a tunnel proved validity of our system to capture improved image target including peeling.
