Enhancing Building Archaeology: Drawing, UAV Photogrammetry and Scan-to-BIM-to-VR Process of Ancient Roman Ruins

This research investigates the utilisation of the scan-to-HBIM-to-XR process and unmanned aerial vehicle (UAV) photogrammetry to improve the depiction of archaeological ruins, specifically focusing on the Claudius Anio Novus aqueduct in Tor Fiscale Park, Rome. UAV photogrammetry is vital in capturing detailed aerial imagery of the aqueduct and its surroundings. Drones with high-resolution cameras acquire precise and accurate data from multiple perspectives. Subsequently, the acquired data are processed to generate orthophotos, drawings and historic building information modelling (HBIM) of the aqueduct, contributing to the future development of a digital twin. Virtual and augmented reality (VR-AR) technology is then employed to create an immersive experience for users. By leveraging XR, individuals can virtually explore and interact with the aqueduct, providing realistic and captivating visualisation of the archaeological site. The successful application of the scan-to-HBIM-to-XR process and UAV photogrammetry demonstrates their potential to enhance the representation of building archaeology. This approach contributes to the conservation of cultural heritage, enables educational and tourism opportunities and fosters novel research avenues for the comprehension and experience of ancient structures.
