Making the Invisible Visible: Virtual/Interactive Itineraries in Roman Padua

PD–Invisible aims to enhance the archaeological heritage of Padua hidden by urban development. The focus of the process is the creation of an adaptive AR App according to the type of user: professionals and researchers on the one hand and cultural tourism on the other. The workflow identifies a path through the city and connects the artifacts studied by the research; catalogue historical and archival documents; detects the structures through laser scanning and photogrammetry technologies; opti-mizes the acquired models both from a graphic point of view and through Scan to BIM; develops the AR App in Unity 3D. The research offers further insights assuming the use of artificial intelligence for this type of applications: differentiate the contents of the App according to the user’s preferences by comparing the GPS data with those of the detection devices (camera and Lidar).
