Project description

The goal of this project was to perform a virtual inspection of this highly frequented railroad tunnel in Seattle. The task was to drive through the double-tracked railroad tunnel using a kinematic scanning system and to inspect and survey the clearance and damage. The recording was carried out at about 5 km/h using the dibit tunnel scanner system, which consists of a hybrid system with laser scanner and high-resolution color cameras. On the basis of the 3D model, profiles were created and analyses carried out.
