CENTRELINE IDENTIFICATION IN A DOCKING GUIDANCE SYSTEM

摘要

The presend invention achieves an accurate and quick centreline identification in a docking guidance system and further a verification of a centreline configuration. Heretofore, it is proposed to scan (S1) an apron in front of a docking stand (16) with a range finder (22) and to register a reflection intensity and position for each scanned point. Then, a centreline (14) is identified (S2) in front of the docking stand (16) 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 (S3) in compliance with the centreline layout.
