3D Surveying and Data Management towards the Realization of a Knowledge System for Cultural Heritage

The research activities involved the application of the Geomatic techniques in the Cultural Heritage field, following the development of two themes: Firstly, the application of high precision surveying techniques for the restoration and interpretation of relevant monuments and archaeological finds. The main case regards the activities for the generation of a high-fidelity 3D model of the Fountain of Neptune in Bologna. In this work, aimed to the restoration of the manufacture, both the geometrical and radiometrical aspects were crucial. The final product was the base of a 3D information system representing a shared tool where the different figures involved in the restoration activities shared their contribution in a multidisciplinary approach. Secondly, the arrangement of 3D databases for a Building Information Modeling (BIM) approach, in a process which involves the generation and management of digital representations of physical and functional characteristics of historical buildings, towards a so-called Historical Building Information Model (HBIM). A first application was conducted for the San Michele in Acerboli’s church in Santarcangelo di Romagna. The survey was performed by the integration of the classical and modern Geomatic techniques and the point cloud representing the church was used for the development of a HBIM model, where the relevant information connected to the building could be stored and georeferenced. A second application regards the domus of Obellio Firmo in Pompeii, surveyed by the integration of the classical and modern Geomatic techniques. An historical analysis permitted the definitions of phases and the organization of a database of materials and constructive elements. The goal is the obtaining of a federate model able to manage the different aspects: documental, analytic and reconstructive ones.

Implementazione del Sistema Informativo 3D: sviluppo di un lessico codificato per una funzionale e produttiva comparazione dei dati

Il progetto del dottorato di ricerca ha permesso di estendere il lavoro svolto sul Sistema Informativo 3D del Cantiere della Fontana del Nettuno al fine di definire la struttura concettuale e i relativi contenuti tematici di una piattaforma open source in grado di sviluppare la documentazione di restauro, sia per opere complesse caratterizzate dalla presenza di molti materiali costitutivi, sia per interventi più semplici nel quale preservare memoria e fornire libero accesso ai dati. Il confronto tra il SI del Cantiere della Fontana del Nettuno con le attuali metodologie utilizzate in campo nazionale ed internazionale ha permesso di ampliare i lessici necessari per la documentazione grafica e testuale da effettuare su diverse classi di materiali, creando delle cartelle integrate da combinare in base ai materiali costitutivi delle opere da restaurare. Il lavoro ha permesso la redazione di un lessico specifico per i diversi materiali costitutivi fornendo una banca dati informatizzata di facile consultazione.
