In this study, the dynamic deflections and vibrations of a belt conveyor system operating in ironworks are observed using a high-speed telephoto mirror-drive active vision system that can simultaneously switch viewpoints and capture magnified images at the rate of hundreds of frames per second (fps). The active vision system captures images of a belt conveyor system at 160 fps using a pan-and-tilt scan mechanism. The images are captured as multiple high-frame-rate video images. The small deflections and vibrations, in multiple belts and pillars, which have peak frequencies of 10 Hz or more are estimated with a precision of dozens of micrometers using image analysis techniques such as digital image correlation when the camera system is placed at a distance of 5 m or more from the conveyor.
