In this study, we propose a novel non-contact vision sensing method for wide-area monitoring of operation of conveyors in ironworks by using a panoramic vibration camera in real time. This method can capture magnified images including vibration contribution from single camera with mirror-driven based viewpoint switching. The small vibrations and rotations in multiple pillars and belts were detected using a function of a full-pixel vibration spectrum imaging which can calculate peak frequencies from time frequency responses. Through some experiments of different situation, such as loading and unloading, we evaluate the efficiency of this method which can monitor the operation of multiple rollers and conveyors, when the camera located in 15 m or more away from the conveyors to be monitored.
