Abstract :
This article presents our first results in reconstructing the 3D structure of a building using primitives delivered by the analysis of the 2D architectural drawings of its floors. A set of features is extracted from the set of architectural symbols available for each floor. A graph of matching hypotheses between the most pertinent features of two consecutive floors is then constructed. A maximal clique detection algorithm supplies the best set of matches. The geometrical transformation allowing each floor to be aligned with respect to its lower floor is computed from the pairs of matching features. The final 3D model of the building is obtained by heaping the 3D models of the consecutive floors
