DESCRIPTIONDESCRIPTION

DOMAINE DE L'INVENTION L'invention concerne un système de vidéosurveillance constitué d'un poste mobile comprenant au moins une caméra vidéo, une unité de traitement apte à numériser et à compresser les données relatives aux images saisies, un module de stockage desdites données et un dispositif d'affichage des images correspondantes. ARRIERE PLAN TECHNOLOGIQUE Les systèmes de vidéosurveillance mobiles connus ne permettent pas, avec exactitude, d'une part, de localiser le lieu où se trouve la caméra et, d'autre part, de connaître son angle de prise de vue. FIELD OF THE INVENTION The invention relates to a video surveillance system consisting of a mobile station comprising at least one video camera, a processing unit capable of digitizing and compressing the data relating to the captured images, a module for storing said data and a device for displaying the corresponding images. BACKGROUND TECHNOLOGY The known mobile video surveillance systems do not accurately allow, on the one hand, to locate the location where the camera is located and, on the other hand, to know its angle of view.

Or ces indications peuvent être extrêmement importantes par exemple dans les cas de vidéosurveillance de zones sans repères où le poste mobile peut être supporté par un véhicule de police ou de lutte contre les incendies où ledit poste peut être supporté par le casque des pompiers. However, these indications can be extremely important, for example in the case of video surveillance of non-landmark areas where the mobile station can be supported by a police or fire-fighting vehicle where said station can be supported by the firefighter's helmet.

On peut ainsi localiser le poste mobile et guider et informer sur le site les intervenants. We can locate the mobile station and guide and inform the site stakeholders.

Claims

SUMMARY OF THE INVENTION The object of the invention is to provide a video surveillance system consisting of a mobile station comprising at least one video camera, a processing unit capable of digitizing and compressing the data relating to the captured images, a storage module said data and a device for displaying the corresponding images and which is essentially characterized in that: the camera comprises a compass capable of giving the camera's angle of view with respect to the magnetic north; - The mobile station has a device of geopositioning able to give the geographical coordinates of the place where the camera is located; the processing unit is adapted to store locally by means of the storage module and / or to transmit remotely by means of a transmission module and / or to display locally by means of the display device, the shooting data; and geographic positioning of said camera and other information such as date, time, temperature, in combination with the image data; the processing unit is adapted to simultaneously display, on the display device, the video image and the site plan, by means of an associated cartographic database, embedding a moving icon according to the geographical position of the camera and an arrow representing, on the plane, the axis of shooting. PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment thereof given by way of non-limiting example and shown in the drawings. attached. In these drawings: FIG. 1 is an overall view of the system according to the invention; FIG. 2 is a detailed view of the composition of the display screen DETAILED DESCRIPTION OF THE INVENTION The video surveillance system shown in the figures consists of a mobile station (M) comprising at least one video camera (1). , a processing unit (2) capable of digitizing and compressing the data relating to the captured images, a storage module (3) of said data and a display device (4) of the corresponding images. According to the basic characteristics of the invention: the camera (1) comprises a compass (5) capable of giving the camera's angle of view with respect to the magnetic north; the mobile station includes a disposition device (6) able to give the geographical coordinates of the place where the camera (1) is located; the processing unit (2) is adapted to store locally by means of the storage module (3) and / or to transmit remotely by means of a transmission module (7) and / or to display locally by means of the device display (4), the shooting data and geographic positioning of said camera and other information such as date, time temperature, in combination with the image data. According to other particular features of the invention, the processing unit (2) is adapted: - to simultaneously display, on the display device (4), the video image (V) and the plane (P ) of the location, by means of an associated map database (8), embedding a moving icon (S) according to the geographical position of the camera and an arrow (F) representing, on the plane, the view; to display, on two distinct zones of the screen of the display device (4), on the one hand, the plane (P) of the place embedding the icon (S) representing the camera (1) and the arrow ( F) representing the shooting axis and, on the other hand, the video image (V) captured by said camera; to manage a database able to record, locally or remotely after transmission, images (V) referenced by the date and time, the geographic coordinates of the camera (1) and the mobile station (M) associated with it; coordinates of the direction (F) shooting; - to search, locally or remotely after transmission, images on criteria of geographic coordinates and directions of shooting. The system according to the invention also comprises at least one remote management unit (9), associated with a transmission means (10), able to receive, store and display the image data and the shooting and geographical positioning data. of said camera and any other information such as date, time, temperature. Of course, the invention is not limited to the embodiments described and shown for which other variants may be provided, in particular in the types and the number of cameras, compasses, devices of geopositioning (GPS or other ), processing units, display devices or remote management units, without departing from the scope of the invention.
