Résumé
The scale models of fortified towns belonging to the Plans-Reliefs collection are exceptional witnesses of the formation of the French territory. The aim of the URBANIA project is the valorisation and the diffusion of this heritage through the creation of virtual models. The town scale model of Strasbourg at 1 : 600 currently exhibited in the Historical Museum of Strasbourg was selected as a case study. We develop and experiment an automatic procedure to identify and reconstruct military architecture works from point cloud digitisation of this fragile and bulky heritage. A priori knowledge formalized in a domain ontology informs the identification of the works – via geometrical feature comparison and consistency evaluation within the fortification system morphology – and their parametric 3D reconstruction refined by direct fit to the initial point cloud.
