Remote bridge inspection using optical methods
Routine bridge inspections usually consist of visual observations. These inspections are timeconsuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, and improve the efficiency and reliability of the acquired data. This study compared the performance of three different imaging technologies for the threedimensional (3D) geometric modelling of existing structures: terrestrial laser scanning, closerange photogrammetry, and infrared scanning. Each technology was used to assess six existing concrete railway bridges. The results suggest that all methods investigated can be used to create 3D models, however, with different level of completeness. ; In2Track: Research into enhanced tracks, switches and structures
