Abstract

L’invention décrit un système de détection d’objets en trois dimensions comprenant : un dispositif d’émission (201), configuré pour émettre des signaux selon un procédé d’émission colorée dans un premier plan, un dispositif de réception comprenant au moins deux capteurs (211, 212) disposés dans un deuxième plan perpendiculaire au premier plan, et des moyens de traitements (230) des signaux émis et reçus, dans lequel les moyens de traitements sont configurés pour détecter la présence d’objets: dans le premier plan à partir des signaux reçus d’un capteur du dispositif de réception en utilisant la coloration du signal émis, dans le deuxième plan à partir des signaux reçus d’au moins deux des capteurs du dispositif de réception. L’invention décrit également le procédé de détermination de la présence d’objets et d’estimation leur direction et distance et le procédé de de mise en œuvre associé. Figure pour l’abrégé : Fig. 2
