TunnelMapper - Full Face 3D Mapping
The paper presents the Geodata TunnelMapper, a novel 3d tunnel face mapping system based on a panoramic camera developed to document the tunnel face area in NATM projects. In particular, the system components, the measurement process, the data acquired, the products derived, the test results achieved and the experience obtained from applying the system at current NATM tunnel projects such as the A26 Linz motorway are presented. The system enables the seamless mapping and digital documentation of the entire excavation area in a simple and highly automated measuring process that can be executed by one single operator. It contributes to the further digitalisation in tunnelling and supports the documentation and pay-off process.
