A method for calibrating a measurement device by a target object is disclosed. Prior to calibrating the measurement device the suitability of the target object is inspected by multiple evaluation criteria. The calibration of the measurement device by the target object is only performed if the target object meets all evaluation criteria. To evaluate the target object, a camera device takes an image of the target object without using a laser beam and an image of the target object with using a laser beam, with the images then evaluated by image processing and object identification procedures.
