Abstract

Des procédés et des systèmes de localisation dans un environnement consistent à déterminer (2402) une estimation de topologie de nœuds situés dans un environnement intérieur dynamique, en fonction de distances mesurées entre les nœuds. Des sous-graphes à noyau k rigide de l'estimation de topologie sont générés (2404) pour déterminer des localisations relatives des nœuds. Des localisations relatives sont transformées (2406) en positions absolues pour générer une carte de positions des nœuds à l'intérieur de l'environnement. Une caractéristique de la carte est déployée (2410) vers un dispositif dans l'environnement.
