• Digital Humanities and Cultural Heritage

From Harris revolution to IT revolution the archaeological process has known considerable technical and technological progresses. Despite of it the methodological process is still stopped at the end of the 70ʼs. The result is that the large use of new technologies in archaeological researches pushes up the growth of a new figure of archaeologist, the Digiarchaeologist, considered as a pure technician instead of a researcher himself. The framework in which we are moving today is made of a huge and indiscriminate use of 3D digital technologies, moving the scientific interest from the methodological problem to the technical one. This paper will try to focus on some important points of the research, such as the importance to make strong considerations and evaluations on the effective advantages of using Laser Scanner technology, the importance of the topological aspects for the stratigraphic excavation, the necessity to improve the technological aspects inside the teaching of archaeological methodologies and techniques.

n the last few years, the use of 3D reality-based techniques in Cultural Heritage has grown significantly. Laser scanner and aerial or close-range photogrammetry have become the new tools for many experts and professionals in the field of documentation and restoration. As it is fundamental to integrate old and new datasets, a common topographical framework is frequently required to guarantee the perfect fusion of data originating from different sensors or acquired in different periods. Integrating the scans with high-resolution images allows to document and evaluate the state of art and conservation of archaeological structures quickly. New methods and approaches are tested to check the reliability and accuracy of the 3D objects, particularly if these digital replicas are the final product of the alignment of separate data-acquisition campaigns (4D). The paper deals with the implementation of a network for the Insula III of Herculaneum, an area greater than 4.000 sqm, since 2005 main case-study of the second research projet of the University of Bologna in Vesuvian region, the Domus Herculanensis Rationes (DHER). The topographical grid, obtained through the alignment and roto-translation of over than 300 scans, has been used to geo-reference and scale the high-resolution images taken during a parallel photogrammetric campaign of the painted and decorated walls of the Insula, in the framework of the Atlante degli Apparati Decorativi di Ercolano, a complete photogrammetric and graphic catalogue of the wall paintings and decorated floors of Herculaneum. The contribution deals with the workflow making the documentary basis of a research on decorations in context (as part of a research in household archaeology, insula based) and mainly on the tests carried out to evaluate the accuracy of the network.

Images used in creation of Photogrammetry model 4 of 4 Multiple innovative digital techniques have been developed to study lithic artefacts (e.g. Olson et al, 2014; Bennet, 2014; Caricola et al, 2018; Grosman et al, 2022 & 2011; García-Medrano et al 2023). Based on its flexibility and relative affordability, multi-image photogrammetry has become an increasingly useful analytical tool within archaeology (Magnani et al, 2020) with Close-Range Photogrammetry being used for lithic analysis (e.g. Caricola et al, 2018; Porter et al, 2016 & 2019; Collins et al, 2019; Bennet, 2021; Timbrell et al, 2022). The imaging approach entails capturing a set of overlapping digital photographs of the subject which are processed with specialised software in order to produce 3D geometry. This dataset comprises part of the dataset of 662 images used to capture the artefact as a compresse zipfile. By downloading these images, along with those of the other three zopfiles, the images can be used to remodel the artefact.
