Abstract

The aim of the invention is to eliminate any overlapping between the footprints of two separate buildings of an urban scene, and to enable the apexes defining the external contour of two 2,5D models of adjacent buildings to be at a pre-determined minimal distance from each other. To this end, a repetitive method for treating a model is characterised in that it comprises: at least one step (210) for detecting an intersection between the footprint of two models; a step (220) for determining a set of models; a step (230) for designating a reference model and a model to be corrected, and a step (240) for modifying the external contour of the model to be corrected, for each model of the set of models; and a step (250) for the aggregation of apexes.
