ABS TRACT:The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy ). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites.
INTRODUCTIONThis research is an analysis of the recording, processing reconstruction and visualisation of the 3D data of a XVIII century watermill identified in an emergency archaeological excavation. The discovery, unearthed during the construction of the minihydroelectric plant, is located on the left bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy).The aim of the paper is to show the possibilities offered by digital technologies, mostly the digital photogrammetry and the virtual archaeology, to record and enhancing the "minor" archaeological sites that are daily subjected to numerous emergency surveys over the entire territory. M ost of these interventions consistently produce vast amounts of data that are often confined to the archives and therefore not accessible to the public.
* Corresponding authorThis work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage to increase the divulgation and visualisation with interactive products. During fieldwork, the methodology and software employed were very sustainable, intended at surveying the site and considering the issues related to the disclosure of the acquired and processed archaeological data; in this way the collected information could be understood not only by scholars and professionals, but also by a larger audience.The paper presents furthermore a case study, replicable in other emergency excavations sites, where archaeological remains, discovered as a result of urban works, are acquired and processed directly on the place of occurrence, non-invasively and through the use of low cost technologies.
