Mise en place d’outils et méthodes de détection des changements dans la maquette virtuelle 3D de La Cub

Abstract : In order to represent faithfully the territory, the update of the 3D virtual model of La Cub is a main issue. This study finds an answer to the issue of changes detection to consider in the model, by the way of methods and a technical implementation of automatics processing. On one hand, a DSM difference leads to the localization of changes. Then, a characterisation step allows specifying the kind of change. A results evaluation shows that few changes are missed, but to the detriment of the large number of false alarms. This processing is operational and usable on all of the community territory. On the other hand, the faithful representation of the territory by the 3D virtual model is verified by the way of a DSM especially created. Experiments show that few models of building are missing: its use is binding regarding the results obtained, but offers the possibility to realize targeted controls.
