3D reconstruction and uncertainty modelling using Fuzzy Logic of Archaeological Structures: applied to the Temple of Diana in Nemi, Italy

Abstract

In the recent years, virtual 3D reconstructions of archaeological sites have gained large attention from various fields of science. Procedural modelling approaches have emerged as appropriate to model and visualize reconstructed ancient structures. The process of reconstructing historical building structures involves ambiguities and uncertainties. On an archaeological site, excavated and surveyed findings such as ruins, located in their original positions, provide reliable foundations for a 3D reconstruction. On the contrary, findings, such as debris of walls, roofs, columns, etc. are not less important, but implicate different levels of certainties for a 3D model, depending on the archaeological knowledge and interpretation. On one hand, this work provides a virtual 3D reconstructing of an ancient Roman temple named “Sanctuary of Diana” located in Nemi, Italy, in different levels of detail using a procedural modelling approach. On the other hand, we present a fuzzy logic approach to quantify and visualize the uncertainty of the temple reconstruction.
