Spatial and temporal location of the keystones in the ribs of the collapsed vaults of Notre-Dame cathedral in Paris (REPARAGE)
As part of the Notre-Dame scientific project, the REPERAGE project is proposing a method for locating the keystones of the vault ribs using a corpus of partially indexed photographs and the temporal chaining of the different states and positions of these elements before and after the fire.
Directly attached to the Notre-Dame de Paris scientific site of the CNRS and the Ministry of Culture, the REPERAGE research project is supported by the MAP laboratory (Models and Simulations for Architecture and Heritage), the Historic Monuments Research Laboratory and the Regional Archaeology Service of the DRAC/IDF. Following the fire at Notre-Dame Cathedral and the collapse of its vaults, the debris was archaeologically processed and documented by photographic coverage of more than 50,000 shots. The massive processing of this photographic data is vital to the cathedral restoration project.
This project proposes a method for :
a) the spatio-temporal location of the keystones in the ribs of the collapsed vaults of Notre-Dame Cathedral in Paris, based on the corpus of photographs taken during the clearing of the rubble and the point cloud readings corresponding to the different temporal states;
b) link these photographs to the heterogeneous semantic data produced by the multi-disciplinary scientific and restoration teams.
From a scientific point of view, the REPERAGE project has made all the data produced available to the members of the Notre-Dame scientific workshop, as well as to the project management team for the restoration work. The project’s innovative methodological approach can be applied to other studies.
In terms of cultural dissemination, the REPERAGE project has contributed to the creation of an educational and promotional kit that combines both the virtual and the physical model to best represent the different aspects highlighted by the researchers.
The case is made up of 3d printed keystones on a reduced scale, enabling the different hypotheses for reconstructing the nave’s double arch to be discussed. The digital environment complements the physical model, with QR codes on each keystone to access the researchers’ data. A high-definition virtual replica of each keystone is also accessible and can be manipulated in a 3d viewer to see details that are not visible on the 3d printed keystones.
