Sažetak
Faculty of Geodesy, University of Zagreb was engaged on the project of 3D scanning and creation of as built documentation for Croatian railways. The aim of the project was to create digital as-built 3D tunnel documentation. The project included 69 tunnels at 7 rail routes with total length of 15 km. Delivery period of tunnel documentation was 6 months. Due the railroad traffic density on this 6 routes, field work was mainly carried out during the night. For the purpose of the project, mobile platform for the scanner was built. Construction of the platform had adapter arms where the circular targets were placed. In this way targets were simultaneously scanned with scanner and determined with robotic total station. Those targets were used as survey control points for placement of individual scans into georeference system. This survey procedure enabled quick scanning of the complete tunnels due to short rail closure time. The scans were processed with Faro Scene, Faro Cloud and AutoCAD Civil 3D software. 3D documentation for tunnels was created. The paper describes new technologies of 3D scanning applied on railway tunnels and process of creating 3D documentation.
