“…The first one was broadcast at the very beginning of the modelling process (Veillard, 2015). Following a study of the superposition of the existing on the hypothetical (Barreau et al, 2014), we applied our methodology in parallel with photogrammetry and various non-textured segments (Fig. 14a) (Debacker, 2019).…”

Highlights: The Portes Mordelaises, a 15 th century defensive gate and associated structures, one of the principal historical sites situated in Rennes, France, has been entirely virtually reconstructed in 3D. An original methodology was adopted in order to reconstruct the 3D model of this unique architectural edifice over the course of its six-year excavation. Recognised as being of great national interest, a virtual reality installation was created in an exhibition presenting its reconstruction, garnering more than 45000 visitors. Abstract:The Portes Mordelaises, remnants of the medieval city walls of Rennes, France, has been the subject of several archaeological excavations until 2017. From these excavations, we created a three-dimensional (3D) model of the site reconstructed as it would have appeared during the 15 th century, including the surrounding plus the interiors of its famed towers. Once our efforts and results were officially recognised as being of national interest by the French Ministry of Culture and Communication, Department of Heritage and the National Museum Service of France, we presented our virtual model reconstruction in an exhibition curated by the Museum of Bretagne, entitled "Rennes, les vies d'une ville" (Rennes, the Lives of a City). This approach to 3D reconstruction of the site served to further study Rennes' origins, its construction, organisation, as well as its historic relationship to surrounding territories. The main objective of this work was to investigate, using of a significant and complex archaeological site as proof of concept, how the digitalisation of an existing structure, the modelling of its hypothetical structures, and the interactions with its virtual spaces enabled the general public to provide critical feedback, and enhance archaeological knowledge and evaluation of such sites. This reconstruction was carried out under a West Digital Conservatory of Archaeological Heritage project, whose mission is to support and advise archaeologists in the production and exploration of 3D archaeological datasets using the latest digitisation, modelling, and virtual reality (VR) techniques. Through a complex but repeatable process, using the valuable data provided by various excavations, in addition to new information provided by the 3D digitalisation itself, we produced a 3D model, fully satisfactory to rigorous scientific standards, which was then incorporated into a VR space ready for diffusion to the general public. Furthermore, the fact that 45850 visitors were welcome to experience our 3D model at an exhibition in a city the size of Rennes proved to be a significant success. Resumen:Las Portes Mordelaises, restos de las murallas medievales de la ciudad de Rennes, Francia, han sido objeto de varias excavaciones arqueológicas hasta el año 2017. A partir de estas excavaciones, pudimos crear un modelo tridimensional (3D) del sitio reconstruido tal y como habría aparecido durante el siglo XV, incluyendo los terrenos circundantes así como los interiores de sus famosas torres.

“…The use of 3D approaches (laser scanning and photogrammetry) has already be experimented for wide and complex archaeological sites such as castles (D'Agostino et al, 2013, Barreau et al, 2014 providing data which would have been difficult and time-consuming to produce by hand drawing.…”

ABSTRACT:This paper will focus on the technical approaches used for a PhD thesis regarding architecture and spatial organization of benedict abbeys in Touraine in the Middle Ages, in particular the abbey of Cormery in the heart of the Loire Valley. Monastic space is approached in a diachronic way, from the early Middle Ages to the modern times using multi-sources data: architectural study, written sources, ancient maps, various iconographic documents… Many scales are used in the analysis, from the establishment of the abbeys in a territory to the scale of a building like the tower-entrance of the church of Cormery. These methodological axes have been developed in the research unit CITERES for many years and the 3D technology is now used to go further along in that field. The recording in 3D of the buildings of the abbey of Cormery allows us to work at the scale of the monastery and to produce useful data such as sections or orthoimages of the ground and the walls faces which are afterwards drawn and analysed. The study of these documents, crossed with the other historical sources, allowed us to emphasize the presence of walls older than what we thought and to discover construction elements that had not been recognized earlier and which enhance the debate about the construction date St Paul tower and associated the monastic church.

A Scan-to-BIM Methodology Applied to Stone Pavements in Archaeological Sites

et al. 2021

View full text Add to dashboard Cite

The transition from Building Information Modelling (BIM) to Heritage Building Information Modelling (H-BIM) is intended to pursue an adequate knowledge of the artefact that is to be preserved, progressively replacing the traditional methods of restoration and structural reinforcement projects with new tools for the management of both existing information and new interventions. The aim of the paper is to show the application of the H-BIM method to a stone pavement road located in the Archaeological Site of Pompeii. In detail, starting from a laser scanner-based survey, juxtaposed with coordinated points georeferenced through a total station, point clouds were handled by means of several BIM-based tools to perform the road design process, starting from the digital elevation model (DEM) and proceeding to the corridor representation. Subsequently, a visual programming application based on Python language was adopted to update the corridor information by means of the object property set. As preliminary results, a tool, complete with graphical and non-graphical information, is proposed to be used in conservation, maintenance and restoration projects.
