Calibration method, production monitoring method and production monitoring device

Abstract

The invention relates to a method for calibrating (48) a production monitoring device (16) for monitoring the production of layer components (12) of fuel cells (72), comprising providing (50) the production monitoring device (16) with a transport device (20) comprising at least one roller element (24) rotatable about a rotary axis (22), over which the belt (26) with the layer components (12) can be guided during production and which has at least one calibration mark (52) on a surface (28) and with a camera (32) directed at the roller element (24) and the belt (26) with layer components (12) that can be guided over it, recording (60) at least one camera image (34) of at least the roller element (24) by the camera (32), and detecting at least one geometric dimension in the camera image (34) by evaluating (42) the camera image (34).Calibration (62) of the detection device depending on at least one calibration parameter (64) of the calibration mark (52). Furthermore, the invention relates to a method for production monitoring (10) and a production monitoring device (16).
