抄録

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