Abstract
In historical and heritage sciences, and in particular in Egypt, the study and publication of the decorated monuments necessarily requires an epidemic survey, which translates into two dimensions and into black and white the three-dimensional and polychromia nature of the object and its decoration. As part of the Belgian archaeological mission to the Nécropole Thébaine (High Egypt), a joint project by ULB and ULiège, the Egyptian ologist Dimitri Laboury and the geomatician Pierre Hallot decided to work together to replace the use of a layer on the wall (and now banned) with the use of rectified photographs, allowing 3D modelling based on high precision photogrammetric reconstruction. The use of a 3D model to produce an epidemic survey is not a trivial operation. A number of questions arise when using this richer source of information than transposition on a calm basis. The faithful reproduction of the building studied leads to questions of projection, colorimetric adjustments, data structuring... During this research, we have had the opportunity to develop a methodology that reproduces as faithfully as possible the traditional recording technique. In addition to the 3D model from photogrammetric modelling, the search results in ortho-photographs of high accuracy both geometric and colorimetric of the walls studied.
