Over the past years, the importance of preserving existing transportation infrastructures has received increased focus. In particular, underground structures require routine inspections and maintenance processes for their optimal use. New possibilities exist now with the mobile terrestrial LiDAR systems, which can quickly scan and record huge data sets that need post-processing techniques to facilitate their efficient use.

This paper describes an automatic method for the detection of tunnel luminaires as well as to easily obtain their 3D spatial location, using colored 3D point clouds. Detection performance was verified by experiments carried on real data acquired with the Lynx Mobile Mapper system in a highway tunnel in southern Galicia, Spain. The method gives promising results after data processing to automatize the detection of luminaires and improve the productivity of tunnel inspections.
