Abstract

Dispositif de positionnement et suivi d’objets se déplaçant sur une scène, comportant : un module de vidéo-projection (10) pour projeter sur la scène en liaison avec un système de traitement d’images (14) une image fixe ou animée formée d’une matrice de pixels d’une résolution déterminée, un module de projection infra-rouge (16) pour projeter sur la scène une image infra-rouge fixe ou animée formée d’une matrice de points d’une même résolution déterminée, un miroir dichroïque (18) pour en liaison avec le module de projection infra-rouge superposer point à point la matrice de point de l’image infrarouge avec la matrice de pixels de l’image projetée, et au moins une caméra vidéo infra-rouge (20) en liaison avec le système de traitement d’images pour définir la position des objets et suivre leur déplacement sur la scène (12).
