The aim of this project was to create a digital, high-resolution 3D model of the tunnels, textured in true color, to be used as a basis for the upcoming tunnel inspection and planning of rehabilitation work. Along the S16 Arlberg expressway, a total of 13.1km of tunnels were recorded at 80km/h using the Dibit high-speed system FSC6100-SRmF10.
In the course of the evaluations, the measurement data from the laser scanner and the high-performance cameras were combined and processed in the Dibit8 software to create a high-resolution, true-color 3D model of the entire tunnel surface including the carriageway (360°). The 3D model was located in the project coordinate system with reference to stationing and tunnel meters.
