Applications of terrestrial laser scanning for tunnels: a review
Journal of Traffic and Transportation Engineering (English Edition), 2014 Abstract:In recent years, the use of terrestrial laser scanning (TLS) technique in engineering surveys is gaining an increasing interest due to the advantages of non-contact, rapidity, high accuracy, and large scale. Millions of accurate 3D points (mm level accuracy) can be delivered by this technique with a high point density in a short time (up to 1 ...

Radiometric correction of laser scanning intensity data applied for terrestrial laser scanning
ISPRS Journal of Photogrammetry and Remote Sensing, 2021 Abstract Alongside spatial information, an intensity scalar is also measured by LiDAR (Light Detection And Ranging) sensor systems. It corresponds to the amplitude of the backscattered laser beam after reflection on the scanned surface. This information isn’t directly usable due to dependencies of geometrical parameters occurring during the scanning ...

Comparative analysis of mobile laser scanning and terrestrial laser scanning for the indoor mapping
Building Research & Information, 2023 Efficient three-dimension exploration of a complex indoor environment remains a difficult duration in mapping accuracy requirements for geometric data. Indoor and outdoor mapping, which has been done with classical measuring devices for a long time, has come a long way with the use of laser scanning technology in this field.
