« The following research aims to exploit the low-cost technologies, for the survey and mapping of historical archaeology in the Roman context. The main purposes of the research is to implement a large-scale survey campaign to understand the geometry and the materiality of the artefacts examined. Three-dimensional survey from photography, allows an immediate mapping of the materiality, of the degradation and of the architectural elements characteristic of the architecture in question. From the model it is possible to obtain an image that is faithful to the reality that can be the basis for developments in many disciplines such as, for example, in the restoration project, for the material analysis and the mapping of the degradation. The applications for this type of mapping are numerous, one of those proposed in this research concerns the virtual musealisation of historical artifacts. More and more in recent years, museums are exploiting the capabilities of three-dimensional modeling software of architectural elements to interactively convey architectural elements. A methodology of work that in recent archaeological excavations is not based solely on the didactic divulgation of the history of a place, but during the excavation phase on the mapping and cataloging of uncovered finds… »



« In 2010 an Italian team started new on-field investigations in the area of the Sun Temple of Niuserra, 6km south of the pyramids of Giza. The archaeological research was planned to re-examine the monument after its discovery in 1898. The work was mainly aimed at a general evaluation of the archaeological structures, still visible, in order to establish an updated plan of the temple. More than 100 scans and several 3D models by close-range photogrammetry have been acquired, processed and integrated to virtually reconstruct the archaeological area. To manage all available 3D datasets, allowing to propose new hypothesis about the monument, a BIM has been developed. Thanks to this approach different categories of environmental and technological objects have been created and analysed. The paper deals with the recent achievements, especially regarding the hierarchical conceptualisation of the architectural components. In particular, the contribution dwells on the analysis of the monument starting from the identification of a parametric library built on the semantic decomposition of the 3D replica…. »


Rééchantillonnage des nuages de points gigantesques produits lors de la numérisation 3D de monuments

« Nous présentons une nouvelle méthode pour rééchantillonner des nuages de points générés par agrégation d’acquisitions LiDAR, à l’aide d’un échantillonnage en disques de Poisson. Celle-ci s’appuie sur un ensemble de graphes locaux représentant la connectivité locale de la surface sous-jacente au nuage, mis en correspondance pour assurer une cohérence globale lors de l’échantillonnage…. »

Technologies numériques 3D et patrimoine, quels enjeux pour demain ?

 » Le domaine des SHS offre de très nombreux champs expérimentaux pour les innovations technologiques. Entre recherche et valorisation, le patrimoine de demain dispose d’atouts exceptionnels que représentent les technologies du numérique. Des appels à projets sur le patrimoine sont régulièrement ouverts, cependant l’obligation qu’ils produisent des innovations technologiques en a freiné le dépôt par les archéologues, historiens, antiquisants, médiéviste, etc. …
