Relevé numérique d’art pariétal : définition d’une approche innovante combinant propriétés géométriques, visuelles et sémantiques au sein d’un environnement de réalité mixte

Abstract : The advances of the last decades in the fields of computer science and metrology have led to the development of efficient measurement tools allowing the digitization of the environment. Although digital technology has not fundamentally overhauled the principles of metric measurement, the improvement of their accuracy, automation and storage capacity has, on the other hand, been a decisive development in many fields. In the case of rock art surveying, their introduction has allowed a massive gathering of 2D and 3D data, meeting various needs for study, monitoring, documentation, archiving, or dissemination. These data provide new and valuable supports for the understanding of the objects of study, in particular concerning their morphological characterization. However, in spite of their great potentials, they often remain under-exploited due to the lack of tools facilitating their manipulation, analysis, and semantic enrichment in multidisciplinary study contexts. Moreover, these methods tend to relegate the cognitive and analytical engagement of the observer behind the measurement tool, causing a deep break between on-site study moments and all off-site processing, or in other words, between real and virtual work environments.This thesis proposes to address these problems by defining an integrated approach allowing the fusion of the geometric, visual and semantic aspects of surveying within a single multimodal mixed reality environment. At the crossroads of the fields of heritage information systems and mixed reality, our goal is to ensure an informational continuity between in situ and ex situ analysis activities. This study led to the development of a functional proof of concept allowing the visualization of 2D and 3D digital data from surveys and their semantic annotation in augmented reality through a web interface.
