High-Speed Motion Blur Compensation System In Infrared Region Using Galvanometer Mirror And Thermography Camera
SENSORS AND SMART STRUCTURES TECHNOLOGIES FOR CIVIL, MECHANICAL, AND AEROSPACE SYSTEMS 2020(2020)
摘要
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.
