Surface shape monitoring device, wear amount measuring system and surface shape monitoring system

摘要

SUMMARY OF THE INVENTION It is an object of the present invention to provide a surface shape monitoring device capable of detecting various abnormalities on the surface of a conveyor belt with a single inexpensive device and reducing operating loss caused by erroneous determination of abnormalities on the surface of the conveyor belt. The surface shape monitoring device of the present invention is a surface shape monitoring device for a conveyor belt, comprising a line laser for irradiating a laser at a wide angle in the width direction of the surface of the conveyor belt, and a line laser from the surface of the conveyor belt. A camera that captures reflected light, a pattern extraction unit that extracts a specific pattern drawn by the reflected light from a captured image of the camera, and the conveyor belt of the pattern extracted by the pattern extraction unit based on the extraction timing. A surface specifying device that specifies a position on the surface and a surface image of the conveyor belt at the position specified by the position specifying mechanism are acquired.
