High-speed motion blur compensation system in infrared region using galvanometer mirror and thermography camera

The infrared thermography method has been used as a non-contact and quick diagnostic technique for the measurement of deformation inside concrete structures. Measurement from the in-vehicle camera is indispensable for quick diagnosis, yet motion blur while running is the essential problem. In this study, we developed a system using the galvanometer mirror and the thermography camera for compensating this motion blur. In the indoor and outdoor experiment assuming the measurement at 40 km/h, it was confirmed that our system compensated the motion blur effectively in the infrared region and detected the delamination of concrete structures.
