(FR) DISPOSITIF DE COMMANDE, PROCÉDÉ DE COMMANDE ET SUPPORT DE STOCKAGE
Abstract:
(EN) A control device for a system generates a virtual viewpoint image based on image data obtained by performing imaging from a plurality of directions using a plurality of cameras. The control device includes a reception unit configured to receive an instruction issued by a user for specifying a virtual viewpoint associated with generation of a virtual viewpoint image, an obtaining unit configured to obtain restriction information for specifying a restriction region where designation of a virtual viewpoint based on the instruction received by the reception unit is restricted, wherein the restriction region is changed in accordance with a parameter associated with the image data, and a notification unit configured to perform a notification based on the restriction information obtained by the obtaining unit.
(FR) Selon l'invention, un dispositif de commande pour un système génère une image de point de vue virtuel sur la base de données d'image obtenues par réalisation d'une imagerie à partir d'une pluralité de directions à l'aide d'une pluralité de caméras. Le dispositif de commande comprend une unité de réception configurée pour recevoir une instruction émise par un utilisateur pour spécifier un point de vue virtuel associé à la génération d'une image de point de vue virtuel, une unité d'obtention configurée pour obtenir des informations de restriction pour spécifier une région de restriction où la désignation d'un point de vue virtuel sur la base de l'instruction reçue par l'unité de réception est restreinte, la région de restriction étant modifiée en fonction d'un paramètre associé aux données d'image, et une unité de notification configurée pour effectuer une notification sur la base des informations de restriction obtenues par l'unité d'obtention.
