Abstract: Terrestrial Laser Scanning (TLS), as an emerging technology, is gradually being applied to various fields such as surveying, and it is the main way to obtain LiDAR high-precision data for ground-based targets. TLS can detect more detailed information about the building, mainly including deformation and damage of the building structure (including shear cracking of the building walls, wall shedding and damage of load-bearing elements), and it can obtain more measurement data such as wall tilt, spatial distribution of cracks, volume and position change calculation, etc. The acquisition of TLS high-precision data provides technical assistance for extracting damage features that are less deformed and cannot be identified by the naked eye. This study reviews and summarizes the research of TLS in building deformation monitoring, 3D modeling, data analysis methods and building ballast loss analysis. After the literature review and in-depth discussion, future research directions of TLS in seismic analysis of buildings are proposed.
