The present invention achieves an accurate and quick centreline identification in a docking guidance system and further a verification of a centerline configuration. Heretofore, it is proposed to scan an apron in front of a docking stand with a range finder and to register a reflection intensity and position for each scanned point. Then, a centreline (14) is identified in front of the docking stand by using differences in reflection intensity between the centreline (14) and the apron surface surrounding the centreline (14). Further, at least two centreline definition points (38, 40) are defined in compliance with the centreline layout.
