Digital photogrammetrical processing and 3D reconstruction for an important archaeological find from Pompeii

Usually archeological artifacts are documented in written or drawn form: today, thanks to the advent of new instrumentations and the development of advanced Geomatics techniques, a new chapter is open about innovative methods of collecting 3D data and new way of heritage representation. The following thesis is talking about the reconstruction of a 3D model of a safe located inside the Obellio Firmo house belonging to the archaeological site of Pompeii, in the framework of a project between Superintendence of Pompeii and the DiSCI and DICAM Departments of the University of Bologna. The technique used fot the safe survey is the close-range photogrammetry: the high quality digital images were taken on the field for further processing in order to obtain accurate textured 3D model processed in different software. In the thesis all the procedures and methods used in order to obtain the 3D model are explained in detail . Since the safe has undergone deformations and melting, because of the eruption of Vesuvius volcano, its original shape is unknown: the work has focused also on the reconstruction of a model representing the original 3D shape of the safe, based on real data coming from the photogrammetric survey and on the analysis of few similar objects found in the archaeological sites of the area
