In this study, dynamic deflections and vibrations of belt conveyors operating in ironworks are observed using a high-speed telephoto mirror-drive active vision that can simultaneously switch viewpoints and capture zooming-in images at hundreds of frames per second. 160-fps video images for a belt conveyor are captured by our active vision system with pan-and-tilt scan as multiple high-frame-rate video images in the experiments, and small deflections and vibrations of multiple belts and pillars, whose peak frequencies are 10 Hz or more, are estimated with the precision of dozens of micrometers by image analysis such as DIC (digital image correlation) when the camera system is 5 m or more away from the conveyor to be monitored.
