Interdisciplinary Data Fusion for Diachronic 3d Reconstruction Of Historic Sites

Abstract

ABSTRACT:In recent decades, 3D reconstruction has progressively become a tool to show archaeological and architectural monuments in their current state, presumed past aspect and to predict their future evolution. The 3D representations trough time can be useful in order to study and preserve the memory of Cultural Heritage and to plan maintenance and promotion of the historical sites. This paper represent a case study, at architectonic and urbanistic scale, based on methodological approach for CH time-varying representations proposed by JPI-CH European Project called Cultural Heritage Through Time (CHT2). The work is focused on the area of Milan Roman circus, relatively to which was conducted both a thorough philological research based on several sources and a 3D survey campaign of still accessible remains, aiming at obtaining the monumental representation of the area in 3 different ages.

Recreate the Ancient Urban Landscape. Multimedia and Interactive Tools to Improve Accessibility and Enhancement of the Archaeological Heritage of Milan

“…These led to the representation of all the information deemed useful for the purpose of documentation and communication of archaeological structures. Within the research project, the documentation activities carried out were mainly focused on the acquisition of geometric, morphological and material information in order to provide valid support bases for all the processes of study, analysis and conservation design, on which the components of the research group, belonging to numerous disciplinary fields, were working on (Micoli et al, 2017). Given the complexity of the sites and their geometric, material and archaeological features, the adopted combination of survey methodologies, including laser scanning, photogrammetric processing and high-definition interactive images, showed to be appropriate for recording the information and characteristics proper to archaeological artefacts, data that are difficult to acquire and to process with the typical two-dimensional survey and representation techniques.…”

Mixing Methods

“…The SfM models of the investigation area, which have already been created from a mixture of different photographic techniques, thus form a core of data from which an array of further data products can be created. The resulting virtual reconstruction of the basis villae (its facade, the surrounding flight of rooms, and its upper floor) shows how valuable an accompanying documentation in 3D can be from the beginning, in some cases with the aid of comparisons to other sites (for a similar approach see Micoli et al 2017). The interaction of different 3D techniques and the resulting new products (in 2D or 3D) are described below.…”
