“…To keep a BIM model up to date, an efficient and flexible method for mapping the interior and exterior environment is needed: The first traditional method is called “CAD to BIM” [ 9 ]. In this method, the 3D representation is provided from existing 2D CAD drawings and is designed according to BIM requirements.…”

“…This whole method remains quite time-consuming and sometimes difficult to implement due to the absence or lack of up-to-date 2D CAD drawings of existing buildings. The second method is the production method with photogrammetric and measurement techniques using Terrestrial Laser Scanning, LIDAR, and UAV, called ‘Scan-to-BIM’ [ 9 ]. Terrestrial laser scanning is the most accurate technique providing millimetre-level accuracy for point clouds captured for BIM models.…”

The combination of LiDAR with other technologies for numerisation is increasingly applied in the field of building, design, and geoscience, as it often brings time and cost advantages in 3D data survey processes. In this paper, the reconstruction of 3D point cloud datasets is studied , through an experimental protocol evaluation of new LiDAR sensors on smartphones. To evaluate and analyse the 3D point cloud datasets, different experimental conditions are considered depending on the acquisition mode and the type of object or surface being scanned. The conditions allowing us to obtain the most accurate data are identified and used to propose which acquisition protocol to use. This protocol seems to be the most adapted when using these LiDAR sensors to digitise complex interior buildings such as railway stations. This paper aims to propose: (i) a methodology to suggest the adaptation of an experimental protocol based on factors (distance, luminosity, surface, time, and incidence) to assess the precision and accuracy of the smartphone LiDAR sensor in a controlled environment; (ii) a comparison, both qualitative and quantitative, of smartphone LiDAR data with other traditional 3D scanner alternatives (Faro X130, VLX, and Vz400i) while considering three representative building interior environments; and (iii) a discussion of the results obtained in a controlled and a field environment, making it possible to propose recommendations for the use of the LiDAR smartphone at the end of the numerisation of the interior space of a building.
