Historic Building Information Modelling (HBIM) is the most effective method of rebuilding virtual 3D
models of heritage buildings, and constitutes a new information management system in the field of
cultural heritage interventions. In this study, photogrammetry based on Unmanned Aerial Vehicles
(UAV photogrammetry) was applied as an alternative to Terrestrial Laser Scanning (TLS) for the
development of HBIM for historical buildings in a ruinous state, analysing as a case study the
Cortijo del Fraile, in Níjar, Almería (Spain). Based on the analysis of the historical information of
the building, a photogrammetric survey was carried out with UAV by means of a combination of
nadiral and oblique photographs. In this way, a precise characterization of the object was
obtained, avoiding the grey areas that are characteristic of TLS. The generated 3D point cloud
served as the basis for the virtual reconstruction of an HBIM model focused on both the exterior
and interior. In order to ...
