- Abstract
- Reconstructing the development of architectural complexes throughout time is often very difficult. Buildings are usually a series of constructive actions, changes from the original project, and collapses and reconstructions due to human actions (such as demolitions) and/or natural disasters (earthquakes, floods, etc.). The building’s structure records all these events, and by using a relief map gives us the chance to understand and decode them. The archaeological relief map is thus supposed to offer a complete and concise documentation. At the same time, it must be enriched with the additional information needed for a more detailed analysis of the archaeological object itself. In the last few years, the introduction and continuous improvements of many instruments (e.g. laser scanners and photogrammetric technologies) have led to a significant qualitative and quantitative change in the recording of material structures. In particular, the possibility of combining different relief technologies - obtaining high resolution, 3D geometrically correct models of buildings or of entire archaeological sites (which could be further investigated thanks to archaeological analysis or other procedures) - has modified the archaeological approach towards the material ‘datum’ and its divulgation. In order to acquire a better knowledge of contemporary technologies, the dissemination of different methodologies - through their application in research contexts - is the best way to transmit and compare them. This article is dedicated to the presentation and detailed analysis of a photogrammetric RGB point-clouds technology, used for the relief of a room during the archaeological excavation at Aiano-Torraccia di Chiusi (San Gimignano, Siena).
