Abstract

La présente invention concerne une caméra de surveillance et son procédé de commande, et plus précisément, une caméra de surveillance capable d'acquérir un point aveugle, et son procédé de commande, la caméra comprenant : un corps principal muni d'une caméra grand angle et d'une caméra à téléobjectif afin d'acquérir une vue de face ; et un corps secondaire (200) capable de modifier librement la zone devant être acquise en faisant en sorte qu'une caméra à champ de vue total faisant saillie soit formée de manière à dépasser d'une face du corps principal et à pouvoir librement tourner vers l'avant, l'arrière, la gauche et la droite. Les caméras de surveillance de l'art antérieur sont réalisées simplement sous la forme de caméras qui ont une faible précision d'acquisition et des champs de surveillance fixes, cela conduisant à des points aveugles qui ne sont pas acquis, et posant un problème de dégradation notable de la fonctionnalité de surveillance. Pour remédier à ce problème, la présente invention propose une caméra de surveillance capable d'acquérir un point aveugle, la caméra comprenant : un corps principal ayant une caméra grand angle destinée à acquérir la totalité du champ de vue vers l'avant du corps principal, et une caméra à téléobjectif permettant d'effectuer un zoom optique sur une zone déterminée et présélectionnée et de l'acquérir, la caméra de surveillance disposant de la caméra grand angle pour acquérir la totalité du champ de vue à l'avant du corps principal, et de la caméra à téléobjectif pour effectuer un zoom optique sur la zone considérée et présélectionnée et acquérir cette dernière, un corps secondaire muni d'une caméra à champ de vue total capable de tourner vers l'avant, l'arrière, la gauche et la droite afin d'acquérir un point aveugle et qui est fixée à un côté du corps principal, les vidéos acquises par la caméra à champ de vue total étant retransmises au multiplexeur du corps principal et une CPU (Unité Centrale) du corps principal commandant le multiplexeur afin de délivrer sélectivement des signaux de sortie acquis par chaque caméra au format PIP. Dans le cas de la caméra de surveillance et du procédé de commande de cette dernière conformément à la présente invention, l'acquisition omnidirectionnelle des zones devant être surveillées est rendue possible par configuration de la caméra de manière à ce qu'elle comporte : un corps principal muni d'une caméra grand angle et d'une caméra à téléobjectif pour acquérir la vue vers l'avant ; et un corps secondaire muni d'une caméra à champ de vue total pour acquérir un point aveugle, le corps secondaire étant relié de manière rotative à un côté du corps principal. Par ailleurs, comme le signal vidéo acquis à partir d'une caméra externe distincte peut être reçu et traité de manière discontinue dans un multiplexeur, le coût de l'installation d'une pluralité de caméras externes peut être réduit de manière significative, et comme un utilisateur peut librement acquérir la totalité des zones souhaitées, le problème des points aveugles se posant pour la surveillance peut être résolu de manière fondamentale.
