  • the invention thus provides a fundamental contribution to improving the visual ergonomics and to increasing the visual information content - without affecting the intuitive orientation - in the 3D output of navigation routes, in particular in the application in the field of motor vehicle or pedestrian navigation.

Abstract

L'invention concerne un dispositif de navigation et un procédé pour produire une vue de carte géographique en 3D (1). L'invention concerne également un produit de programme informatique y afférent ainsi qu'un moyen de stockage numérique. L'invention est caractérisée en ce qu'une extension en hauteur (4, 5) dans la troisième direction spatiale est associée à l'itinéraire de navigation (2), en ce sens que l'itinéraire de navigation (2) est rendu dans la vue cartographique (1) comme un objet d'itinéraire de navigation tridimensionnel (2, 4, 5) et est ensuite affiché. L'invention permet d'obtenir une reconnaissance complète du déroulement d'un itinéraire de navigation même quand l'itinéraire de navigation proprement dit, représenté dans la vue cartographique au niveau des rues, ou encore les rues parcourues par l'itinéraire de navigation ne sont plus visibles, notamment quand celles-ci sont cachées par des modèles de bâtiment en 3D dans la vue cartographique.
