DESCRIPTIONDESCRIPTION

DOMAINE DE L'INVENTION L'invention concerne un système de vidéosurveillance destiné à l'observation d'un environnement donné au moyen d'une pluralité de caméras reliées à une unité de commande et de surveillance; ledit environnement étant constitué d'au moins une série d'obstacles délimitant au moins une série de zones à surveiller; ladite unité de commande comportant généralement au moins un moniteur vidéo et une mémoire de stockage des données et des programmes destinés au pilotage des caméras; la surveillance dudit environnement étant assurée par au moins une caméra fixe équipée d'un objectif apte à permettre une prise de vue grand angle de ladite zone et par au moins une caméra, mobile en translation, en site et en azimut, équipée d'un objectif de focale fixe ou variable.  FIELD OF THE INVENTION The invention relates to a video surveillance system for observing a given environment by means of a plurality of cameras connected to a control and monitoring unit; said environment being constituted of at least one series of obstacles delimiting at least one series of areas to be monitored; said control unit generally comprising at least one video monitor and a data storage memory and programs for controlling the cameras; the surveillance of said environment being ensured by at least one fixed camera equipped with an objective adapted to allow a wide-angle shooting of said zone and by at least one camera, mobile in translation, in site and in azimuth, equipped with a fixed or variable focal length lens.

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

On connaît de nombreux systèmes de vidéosurveillance qui comportent une pluralité de caméras destinées à l'observation d'un environnement constitué de zones délimitées par des obstacles.  Many video surveillance systems are known that include a plurality of cameras for observing an environment consisting of areas delimited by obstacles.

C'est par exemple le cas de l'observation d'allées délimitées par des rayonnages que l'on rencontre principalement dans les grandes surfaces.  This is for example the case of the observation of aisles defined by shelves that are encountered mainly in supermarkets.

Les systèmes connus destinés à l'observation de ce type d'environnement sont de deux types: a) le premier consiste à utiliser un jeu de caméras fixes disposées pour l'observation des espaces de circulation longitudinaux et transversaux existant entre lesdits rayonnages: cette solution ne permet pas de suivre dans le détail l'objet (individu) qui évolue dans lesdits espaces; b) le deuxième consiste à utiliser des caméras mobiles en site et en azimut, équipées d'objectifs à focale fixe ou variable et disposées pour l'observation des espaces de circulation longitudinaux et transversaux existant entre lesdits rayonnages: cette solution permet certes de suivre dans le détail l'objet (individu) qui évolue dans lesdits espaces mais nécessite un investissement plus conséquent en matériel et en logiciel.  The known systems for observing this type of environment are of two types: a) the first is to use a set of fixed cameras arranged for the observation of the longitudinal and transverse circulation spaces existing between said shelving: this solution does not allow to follow in detail the object (individual) that evolves in said spaces; b) the second is to use mobile cameras in site and azimuth, equipped with fixed or variable focal length lenses and arranged for the observation of the longitudinal and transverse circulation spaces existing between said shelving: this solution allows certainly to follow in the detail the object (individual) that evolves in these spaces but requires a greater investment in hardware and software.

L'invention vise donc à réaliser un système de vidéosurveillance qui combine les deux solutions précédentes de façon économique tant au niveau du matériel que du logiciel et de façon à en faciliter l'exploitation et en augmenter les performances, principalement dans la localisation et le suivi détaillé de l'objet (individu) observé.  The invention therefore aims to provide a video surveillance system that combines the two previous solutions economically in terms of hardware and software and to facilitate operation and increase performance, mainly in the localization and monitoring detailed object (individual) observed.
