![]() Traditional semi-automatic methods for surveying the exact rail location are very complex and costly. However, the geomorphological condition of the ground in the port continually leads to significant subsidence and track changes in the rail systems, which therefore must be regularly checked and maintained. The RMGC is subject to great demands in terms of unchanged position and exact tracking. There the rail mounted gantry cranes (RMGC) pick up the container and either put them in the block for storage or bring them to the land side for further transfer. The containers are loaded from the ship to an automated guided vehicle (AGV) which carries them to the storage block for temporary storage. The Container Terminal Altenwerder (CTA) is a highly automated terminal located in Hamburg and contributes heavily to transport through the shipping industry. The results show that the required accuracy of the rail position with an RMSE of 3 mm in XY plane and 8 mm in altitude can be achieved with comparatively less disruption of regular block activities. Furthermore, an automated rail delineation in the derived surface model was developed and evaluated with ground reference measurements. In this paper, the results of the test campaign, carried out in June 2020, were presented where different cameras (150 mm and 80 mm telelens) and flight speeds (1.1 m/s and 1.9 m/s) at a 35 m flying height were performed. The research project AeroInspekt proposed a fully automatic measurement of the position of the tracks using UAV-based photogrammetry. The traditional semi-automatic surveying methods are slow and require the interruption of the activities in the storage blocks. The allowed tolerances are in the range of 10 mm in the XY plane on a track length of 300 m. The regular inspection of the crane tracks of storage cranes at the Container Terminal Altenwerder (CTA), Hamburg requires high accuracy of measurements to determine its position. ![]()
