Virtual 3D reconstruction of Plans-Reliefs from historical document analysis for valorisation applications
The French collection of Plans-Reliefs, scale models of fortified towns, constitutes an awesome architectural heritage. Facing this patrimonial richness, many cities, represented on these plans-reliefs, would like to expose, develop and exploit this historical heritage. However, the fragility, the dimension of the supports and the exposure conditions makes this acquisition difficult. Thus, the creation and the exploitation of a virtual model constitute an interesting alternative. This paper presents a method exploiting historical documentary for the 3D semantic modelling and the valorisation of the virtual Plan-Relief of Verdun. The original Plan-Relief is currently enclosed in containers in Paris.
