Abstract
Un système de détection dune classe dobjets à un emplacement, par exemple, des humains sur une courroie de convoyeur. Une caméra thermique peut être utilisée pour détecter des objets et la variance de la distribution thermique dobjets pour les classer. Les objets détectés dans une image provenant dune caméra peuvent être détectés dans une image dune autre caméra utilisant une correction géométrique. Une caméra couleur peut être utilisée pour détecter le nombre de bords et le nombre de couleurs dun objet pour le classer. Une caméra de couleur peut être utilisée avec un classificateur de corps humains verticaux pour détecter les humains dans une zone, et des nuées correspondant aux humains détectés peuvent être suivies dans une image de caméra thermique ou couleur pour détecter si un humain entre dans une zone interdite adjacente comme une courroie de convoyeur.
