Abstract
A belt conveyor calibration method includes transporting a marker by a belt of a belt conveyor, imaging the marker by a first camera, detecting the marker passing through one section of a plurality of sections formed by division of a first imaging area of the first camera from a captured image of the first camera, moving a second camera by a robot and tracking and imaging the detected marker by the second camera, and calculating and storing a correction value as a difference between a position of the marker estimated from a transportation amount of the belt and a position of the marker detected from an image of the marker tracked and imaged.
