Abstract
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 ensure reasonable agreement between the parametric model and the ground truth, a validation procedure has been established that restricts the deviations between the two. Finally, a texturizing process is applied to the HBIM model to achieve a photorealistic finish for purposes of visualization, archiving, and recording.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
