Portable laser scanning solutions for 3D modelling of large buildings

Abstract. Portable laser scanning systems (PLSSs) are a developing technology that is being used more frequently in various application domains. One notable characteristic of these systems is their capacity to gather 3D data while in motion. Additionally, unlike mobile mapping systems that are mounted to vehicles, they are particularly effective at capturing detailed information in tight, interior, and restricted spaces. This article presents two typical applications of this promising technology for modelling huge buildings. The purpose is to equip readers with fundamental information and comprehension of the capabilities and obstacles associated with this technology. A comparison is made of two methods of interior spatial data collection with lidar technology - ground-based laser scanning with a Trimble TX6 and a handheld GeoSLAM ZEB Horizon device. The technological process for creating a 3D model of two large buildings for future reconstruction is described.
