UAV PHOTOGRAMMETRY AND HBIM FOR THE VIRTUAL RECONSTRUCTION OF HERITAGE

Abstract. Three-dimensional (3D) models have become a great source of data for the conservation, reconstruction, and documentation of emblematic buildings of cultural heritage. In this study, photogrammetry based on Unmanned Aerial Vehicles (UAVs) was applied to perform a photogrammetric survey of a dilapidated cultural heritage building. On the basis of this survey and the historical information gathered from the building, its virtual reconstruction has been carried out using a Historic Building Information Modeling (HBIM); applying realistic materials and textures in order to document it.
