LASER SCANNING FOR TUNNEL STATE ASSESSMENT

In this paper a technology to obtain a maintenance and safety inspection in tunnels is presented. The measurements are carried out with a laser scanner. This measurement method is fast and reliable and does not obstruct the normal traffic or work in the tunnel. In addition to the surface covering visual and thermal image, distance measurements can be obtained. All the data is stored on a normal PC. That means the tunnel is always ready for inspection in the office. (A) For the covering abstract see IRRD E101472.
