[Termes IGN] résiduRésumé : (auteur) In this paper, a new method for reconstruction of 3D segments from multiple images in urban areas environment is presented. Compared to previous algorithms, this one performs the matching of 2D segments in the Object Space through a sweep plane technique, thus avoiding the combinatorial exploration of all possible correspondences and handling images in a symmetric way. Furthermore, a method for reconstruction of 3D line from 2D lines, which takes into account the uncertainty on the parameters that define the 2D lines is also presented. It enables to get normalized residuals, which is used as a geometric criterion usable whatever the number of images is, to assess or reject potential correspondences. This criterion along with an unicity criterion is at the heart of the algorithm to prune the set of possible correspondences and to keep only reliable matches. Promising results are presented on simulated and real data. They show the ability of the algorithm to overcome detection errors in images and its robustness to occlusions in some images.

[Termes IGN] texture d'imageRésumé : (auteur) We present a set of algorithms that recovers detailed building surface structures from multiple images taken under normal urban conditions, where severe occlusions and lighting variations occur and are difficult to be modeled effectively. An iterative weighted-average algorithm is designed to recover high-quality consensus texture of the wall facades. A generic algorithm is developed to extract the 2D microstructures. Depth is estimated and combined with 2D structures to obtain 3D structures, facilitating urban site model refinement and visualization.

[Vedettes matières IGN] GénéralisationRésumé : (auteur) During the cartographic generalisation process, geographic objects cannot just be considered one by one. The way objects are processed clearly depends on their spatial context. In this paper, we first study the nature of spatial context encountered dur ing map generalisation. We differentiate three kinds of relations that an object can have with its environment: being part of a significant group, being in a particular area, being in relation with 'same-level' surrounding objects. We also address the issue of scale- dependency related to spatial context. Then, we study how to represent context-related knowledge in a knowledge-based approach of cartographic generalisation. We discuss several aspects of the representation of objects' spatial context in a geographic data model dedicated to map generalisation: explicit representations of high-level objects, fuzzy representation of objects and relations, multi- scale representation of objects and relations, spatialisation of relations. We also study how context appears in the rules expr essed by cartographers to describe the generalisation process: it can be used to express exceptions, to classify typical operations to b e done, or to express constraints on the final result.
