[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) Even though many efficient building reconstruction methods have been published so far, automatic processes are still missing for the production of 3D city models. This gap between research results and effective production tools seems mainly due to a lack of cooperation between all these methods. Building reconstruction in dense urban areas is such a complex problem that it is hopeless to look for an universal solution that could efficiently reconstruct every building, from a simple gabled roof to a whole cathedral. In this paper we first present a general strategy to combine several automatic and user-assisted processes to produce three-dimensional city models in a real production context using aerial images and 2D ground maps. The strategy aims at taking advantage of each algorithm to be sure they complement each other. Then we illustrate this strategy by describing our operational implementation and its results. In this implementation, the first step is a combination of two automatic algorithms: a model driven and a data driven process. In a second step, user-assisted tools supplement the reconstruction: some are adapted to precise landscape features while others are more generic.

[Termes IGN] zone urbaineRésumé : (Auteur) This paper describes a purely geometrical approach for matching and chaining edgels, i.e. contours points with their tangent direction, to reconstruct in a general way 3D rectilinear or curved surface boundaries from multiple calibrated images. Results show that the 3D reconstructed edgels are highly reliable and accurate, and correctly reproduce the 3D limits of very small image structures thus demonstrating the high resolving power of this technique and enabling a finer description and understanding of urban scenes. 3D Edgels are a key feature for reconstructing man-made objects. Practical examples of edgels reconstruction are given on various type ot 3D objects (roundabouts, zebra crossings, cars, classical and odd shape buildings, dormer Windows) in surveys at a ground pixel size of 25 cm. Practical examples of edgels integration within a surface reconstruction or 3D pattern recognition and object extraction processes are also provided. Indeed 3D edgels can be used as characteristic and constraining lines for the surface topography reconstruction and used to build the limits of cartographic objects thus ensuring a natural geometrical and topological coherence between Digital Surface Models and Digital Object Models.
