A method of resolving ambiguities between at least two pointers within a region of interest divided into a plurality of zones comprises capturing images of the region of interest from different vantages using a plurality of imaging devices; for each zone, processing images from a different set of imaging devices to identify a plurality of targets for the at least two pointers; and analyzing the plurality of targets to resolve a real location within the region of interest associated with each pointer.

Un procédé de résolution d?ambiguïtés entre au moins deux pointeurs dans une région présentant un intérêt divisée en une pluralité de zones consiste à capturer des images de la région présentant un intérêt à partir de différents points d?observation au moyen d?une pluralité de dispositifs d'imagerie ; traiter, pour chaque zone, les images provenant d'un ensemble différent de dispositifs d'imagerie pour identifier une pluralité de cibles pour la pluralité de pointeurs ; et analyser la pluralité de cibles pour résoudre un emplacement réel dans la région présentant un intérêt associé à chaque pointeur.
