  Measurement of geological joint faces from point clouds - application in tunnel

  Abstract: 3D point clouds have recently become a tried-and-tested instrument of assessing geological joint faces. Especially in the case of only brief outcrops during tunnelling, they offer the opportunity to carry out in-depth analyses in a virtual environment without time pressure and risk. These include dip and strike of geotechnically relevant structures, their roughness, the direction of fault zones...

  New approaches in photogrammetric high -speed 3D tunnel monitoring

  Abstract: In tunnel condition assessment, the trend is towards comprehensive 3D measurement combined with high quality image texture to document and quantify damages to the tunnel surface and to create a cohesive data base of the structural conditions throughout its lifespan. The faster such measurements can be made on-site, the less it impacts shut down times to the regular traffic. Also surveying costs...
