Objectif scientifique
Les activités de G-Mod couvrent 3 thèmes qui interagissent selon les projets et développent une activité large et cohérente en modélisation géométrique.
Analyse géométrique et topologique
L’analyse de caractéristiques locales ou globales de données géométriques est la base de méthodes de modélisation, d’appariement, ou de représentations multi-résolution. Ces travaux permettent la reconnaissance de formes prédéfinies, de lignes caractéristiques, de zones homogènes, sur des objets variés (maillages de triangles, nuages de points, objets abstraits décrits par la topologie).
Modélisation – Reconstruction
Ce thème ajoute une abstraction aux données géométriques en joignant la connaissance sémantique. Ces propriétés sont fournies a priori (modélisation déclarative), ou extraites d’un objet numérisé (caractérisation). Cela induit la mise en place de contraintes de différents niveaux (de la donnée vers l’expertise-métier), résolues par des techniques spécifiques.
Fusion de données et modélisation pour la simulation graphique
Dans les modèles multi-représentation, la fusion de données et la simulation graphique se basent sur la modélisation géométrique. La fusion d’information enrichit les données mais induit de la redondance. Quels que soient le réalisme des images produites ou les moyens utilisés, la difficulté est la communication cette information. La modélisation est alors un support de représentation de la connaissance (recalage spatial, indexation de données sémantiques).
