Abstract
Procédé de contrôle d'une ou plusieurs z-caméras à partir d'un ensemble de caméras afin d'obtenir des flux d'images captant un objet d'intérêt; comprenant la réception de données de position et de données d'objet correspondant à l'objet d'intérêt; la détermination d’un sous-ensemble d’une ou plusieurs z-caméras ayant une zone de couverture potentielle comprenant l'objet d'intérêt; le calcul de la position relative de l'objet d'intérêt par rapport au centre du champ de vision de la z-caméra; le calcul d’un facteur de zoom calculé en déterminant un angle de champ de vision le plus étroit de la z-caméra qui englobe la totalité de l'objet d'intérêt; et la génération des commandes de transmission pour le sous-ensemble de la ou des z-caméras en fonction du facteur de zoom calculé.
