Proposition d’une ontologie de domaine dédiée à l’annotation d’images spatialisées pour le suivi de la conservation du patrimoine culturel bâti

Abstract : The conservation and restauration of historical monuments require a diagnostic analysis carried out by a multidisciplinary team. The elaboration of the diagnosis of a cultural Heritage Object requires direct observations, the examination of documentary sources as well as of diverse types of analytic data. The great advancements in digital processing, management and data collection opened unprecedented opportunities for integrating results, coming from both observations and derivative data, within innovating representation systems for heritage knowledge and documentation. However, if a range of new tools and data is today available to the scientific community and heritage experts, their correlation and integration with internal/external heterogeneous information is an issue that still remain unexplored. While these innovative tools allow different experts to record and analyze their observations with diverse formats, the results are generally not spatialized and referenced together. Indeed, even though all these data refer to a common physical object, the links between them is based only on file organization strategies or by keyword-based indexation methods. In parallel, in recent years, several 3D digitization technics has been used for generating dense and accurate geometrical representations, but the processing and structuration method of these 3D data don’t include yet an operational framework for retrieving relevant information regarding their conservation state and an interpretative analysis. Positioned in the intersection between 3D spatialized acquisition domain and information management, this research work aims to the creation of a digital framework for recording conservation state description of historical monument throughout the introduction of a functional domain ontology for the semantic annotations of heritage objects 3D representations. The proposed ontology comprises both qualitative (related to a domain knowledge formalization) and quantitative descriptors, constituting the necessary conceptual scaffold for structuring a multidimensional information system dedicated to the correlation of spatial, geometrical and semantic multi-actor annotations in relation to multiple observation levels.
