Abstract

Des modes de réalisation de la présente divulgation proposent une solution de fusion de résultats de détection et de positionnement. Dans une solution, un premier dispositif de communication obtient un résultat de détection d'une cible dans une zone de détection et un résultat de positionnement de la cible. Le résultat de positionnement indique au moins une position de la cible dans la zone de détection. Le premier dispositif de communication effectue une fusion du résultat de détection et du résultat de positionnement.
