Abstract

L'invention concerne un procédé permettant de détecter des objets dans une zone. Ce procédé consiste à obtenir une ou plusieurs images de la zone, à utiliser une technique de détection des bords de manière à mettre en relief les caractéristiques linéaires dominantes dans l'image ou les images et enfin à déterminer si ces caractéristiques linéaires dominantes recoupent des caractéristiques linéaires définissant la zone. Ce procédé consiste à détecter une parallaxe dans au moins deux images, cette parallaxe étant produite par la présente d'objets tridimensionnels dans la zone.
