Elaboration d'une méthodologie de relevé d'objets architecturaux : contribution basée sur la combinaison de techniques d'acquisition

Abstract : The external survey of an architectural work is a way to create a representation of the building in its conservation condition. Two techniques of remote acquisition differ by their effectiveness and the quality of the produced data: photogrammetry and laser scanning. These two techniques depend on optical principles: what cannot be seen cannot be measured. The combination of these techniques can improve the data quality, but unmeasured zones always remain, therefore cannot be represented. In order to solve this problem, we put forward the hypothesis that using architectural knowledge may allow to rebuild these zones during the modeling process. This study suggests a modeling process based on the combination of these two techniques and on the integration of the available architectural knowledge, from paper documentation or from the built works construction rules. An architectural work being complex and the data numerous, a division of the modeling process in several distinct stages appears necessary. We suggest dividing modeling process according to different figuration of level of details frequently used to represent architecture, and define a process using information in a progressive way. Thus our approach consists in integrating dimensional data into architectural documentation, in order to develop a modeling process providing a model as complete as possible.
