Abstract:
This article aims to present the methodology we developed for the realization of 3D reconstruction photogrammetries on the inside cellars by the research program of ancient cellars of the Brussels-Capital Belgian Region (BAS – Brussels Archaeological Survey).
The specificity of those studied cellars and lower rooms inferred a number of constraints that we must take necessary into account in this methodology implementation as the lack of space and luminosity or the presence of “modern” developments which can obstruct the access of masonries elements to study.
This methodology was in constant evolution for several months and started to be refined according to sites topology: we constantly search to perform in the process simplification, in shots number reduction and in acquisition time optimization through the implementation of a particular prospect merging cross-techniques of 3D scanner data acquisitions mixed with classical full photographic photogrammetry.
The purpose of those acquisitions intends to produce the most precise possible recording of hardly accessible spaces as a unique chance of study because they are either private, heavily modified or perhaps they could soon disappear.
Finally, besides the scientific point of view, these cellars records establish an excellent
mediation and distribution tools of the archaeological studies with a wider public.
