The invention relates to a method for calibrating 3D laser scanners (20). The laser scanner is fixed on a support structure (12) of a crane used for container transportation, so that the containers (18) can be scanned in a working zone of the crane. The calibration includes at least one scanning of a calibrator (24) having ISO container features. The calibrator has a calibration mark (26) and can carry recognition and positioning during a scanning process. The method measures movement offset of at least one laser scanner relative to the support structure if the movement offset is not known. The crane is controlled, so that the calibrator can be caught and brought to different predetermined heights above the ground (8) and the scanning of the calibrator is performed through at least one laser scanner. The rotation offset of the at least one laser scanner (20) relative to the support structure (12) can be measured with the scanning result and the movement offset.
