Abstract / Hauptanspruch
An information processing system for identifying a position of a workpiece conveyed on a conveyor is provided. A counter measures a movement amount of a conveyor a plurality of times at intervals shorter than a cycle of communication with a controller, and transmits measured movement amounts and respective measurement timings to the controller. The controller receives a position of a workpiece measured from an image obtained at a set imaging timing, identifies measurement timings relatively close to the imaging timing from among measurement timings, identifies a reference movement amount associated with the measurement timing, identifies a reference position of the workpiece at the imaging timing based on the position of the workpiece within the image, and adds a difference between the current movement amount of the conveyor and the reference movement amount to the reference position to calculate a current position of the workpiece.
