Abstract

La présente invention porte sur un système d'extraction d'une zone cible à l'aide d'une pluralité de caméras, et sur son procédé. Le but de la présente invention est de proposer un système et un procédé pour effectuer une acquisition d'image en temps réel et apparier des mises à jour par emploi d'un procédé qui utilise une image résultante appariée dans un cadre d'une caméra, de façon à effectuer un appariement en temps réel à un cadre d'image d'une autre caméra, c'est-à-dire un suivi en temps réel par mise à jour d'images détectées par une pluralité de caméras et appariement croisé. Pour atteindre le but ci-dessus, le système de la présente invention comprend : une pluralité de dispositifs de caméra acquérant chacun une image d'une cible ; un dispositif de suivi pour suivre une zone cible par utilisation d'une image introduite en temps réel par le dispositif de caméra ; et un dispositif de surveillance pour commander le dispositif de suivi conformément à des informations de commande provenant de l'utilisateur, et délivrer en continu une image qui suit la zone cible.
