Abstract
The acquisition of the spatial data in architecture has known in these last years significant progress due to the development of new laser-based measuring techniques. In parallel, several geometrical three-dimensional processing techniques (point-cloud segmentation, surface reconstruction, depth maps, parametric modeling, image-based modeling, etc.) allow to produce 3D geometrical representations for the analysis of the object at various levels of details and for various purposes (real-time navigation, measurement and shape analyses, mechanical studies, etc.). However, starting from the 3D digitized point clouds, the representation problems are essential, because an efficient 3D reconstruction process of a building requires architectural knowledge interpretations to describe architectural objects. This thesis propose an approach to drive the 3D reconstruction operations using a whole of historical knowledge specific to the architectural forms layout. A semantic description model is used as common denominator between various geometrical representations and information sets extracted from the surveying process. The digital models obtained can be exploited for the constitution of patrimonial databases. Within this framework, an approach to structure the digital models witch describe the building according with spatial and architectural requirements has been developed. The digital mock-up thus produced plays a strategic role to support real-time navigation into the virtual representation of the building and to manage the interactions with its associated documentary sources. The documentary information and the multiple geometrical representations of the objects constituting the building can to be managed and updated in a dynamic way according to various user points of views such as.
