Definitions

  • This invention relates to a system for controlling multiple video cameras This invention allows for a convenient user interface for selecting and directing a camera within a multi-camera system, as might be used in a security system or a multi-camera broadcasting system
  • Secu ⁇ ty systems for airports, casinos, and the like typically employ a multitude of cameras which provide images of selected areas to a control station The images from each of these cameras, or a subset of these cameras, are displayed on one or more monitors at the control station.
  • the operator of the control station is provided an ability to select any one of the cameras for a display of its image on a primary monitor, and, if the camera is adjustable, to control of the camera's field of view
  • Such control systems are also utilized for selecting from among multiple cameras at an event being broadcast, for example, multiple cameras at a sports arena, or studio.
  • the selection and control of the cameras is typically accomplished by controlling a bank of switches, or by selecting from amongst a list of cameras on a computer terminal.
  • Each camera is identified by a unique number, or by a unique name, for example
  • the operator selects the camera associated with that area If the camera is adjustable, the operator subsequently adjusts the selected camera's field of view by adjusting its rotation about a ho ⁇ zontal axis (pan) or vertical axis (tilt), or its magnification (zoom) This control is often facilitated by the use of a jovstick
  • the selection of views may be automated, by having a fixed set of camera selections and associated fields of views predefined, and having each of these predefined views presented to the operator in a pe ⁇ odic sequence The operator may preempt the sequencing of these views to select alternative views, as needed.
  • the selection and adjusting of a camera may also be automated in response to an alarm signal.
  • the operator In order for the operator to view a particular scene, the operator must be aware of the potential fields of view of each of the cameras, and the identifying name or number associated with the camera which includes the desired scene. After selecting the appropriate camera, the operator must adjust the camera from its current field of view position to the field of view which contains the desired scene. To alleviate the burden associated with viewing particular scenes, some systems allow for the operator to select from a list of commonly viewed scenes. Again, however, the operator must be aware of the identifying name or number associated with the desired scene. While it may be desirable to have many commonly selected scenes prerecorded, for ease of camera selection and adjustment, each additional prerecorded scene makes the task of identifying a particular scene by name or number more cumbersome.
  • This object is achieved by providing a graphic representation of the secured area.
  • the system determines which camera contains this point within its possible field of view, then selects the camera for viewing and adjusts the camera to contain the selected point in the viewed image. If multiple cameras contain the point, the user is provided the option of scrolling through each. The user is also provided a means of easily adjusting the camera after it is automatically selected.
  • the graphic representation for example, in the form of a floor plan of a secured building, the operator need not memorize the identification name or number of each camera, nor need the operator know which camera or cameras cover a given area.
  • the operator is provided a graphic representation of the current field of view of a selected camera.
  • Security systems often automatically select a camera associated with an alarm, for presentation of a view of the alarmed area to the operator. Unless the operator is familiar with the view being presented, it often takes a few moments for the operator to determine where, in the actual secured area, the camera is viewing. By presenting a graphic indication of which alarm has been triggered, which camera has been selected, and which view the camera is currently displaying, the operator can more easily be oriented to the displayed scene, and can more easily assess the security situation. The operator can thereafter refine the view of the scene by the aforementioned graphic camera interface capabilities.

  • Monitors 150, 151, 152, 153 are also connected to the switch, for viewing the images from the cameras.
  • One of the monitors, monitor 150 is used as the main viewing screen, typically displaying the image from one of the cameras selected by the operator.

  • Associated with each camera will be a polygon, outlining each camera's potential field of view.
  • Shown in Fig. 3a is the polygon associated with camera 102;

  • the level of detail of the polygons is relatively arbitrary; typically, one would provide the detail necessary to cover the maximum surveillance area within the secured area. If one area is coverable by multiple cameras, the need is minimal for identifying the fact that a particular camera can also view that area by viewing through a doorway. Conversely, if the only view of an area is through such a doorway, the encoding of the polygon to include this otherwise uncovered area may be worthwhile. Similarly, although an unobstructed view of a camera is infinite, polygon bounds can be defined to merely include the area of interest, as shown for example in Fig. 3c, where the bounds 249-250 and 253-254 are drawn just beyond the perimeter of the area being secured.

  • the camera locations may be in the form of dimensions used on the blueprints for the building.
  • the coordinate system used will be the screen coordinates, unless otherwise noted. Alternate views may also be presentable, for example, each floor of a multistoried building may be presented.

  • This selection may be arbitrary or based upon some algorithm, for example, the camera closest to the coordinates of point P may be the selected camera. If the point P does not lie within any of the camera's field of view, an error message may be presented (not shown). Having selected a camera, the direction of the point P from the location of the camera can be determined, at 460. This direction is the desired line of sight for the selected camera; the selected camera is adjusted to this line of sight at 470. Thereafter, the point P will appear in the center of the camera's displayed image in the monitor 150. If the camera is not adjustable, the point P will appear within the camera's displayed image, albeit not at its center.
  • the preferred system will appropriately adjust the zoom in dependence upon the distance of the point P from the camera position. For example, if the point P is very close to the camera position, a low magnification would be employed, whereas if the point P is very far from the camera position, a high magnification would be preferred.
  • an target span of view will be defined. The zoom will be adjusted dependent upon the distance between the camera and the identified point such that the arc-length of the camera's span of view is equal to this target span of view at the point. After adjusting the camera, the system returns from this routine, at 499, for subsequent user input.
  • the user is provided a means of selecting another camera, shown at 480.
  • the operator is provided an ability to sequence through all the marked cameras.
  • the user enters an alternative-select command, and the system selects the next marked camera; if another marked camera does not exist, the system reverts to the selection of the first selected camera, thus cycling through all marked cameras repeatedly.

  • the alarm sensor is a switch attached to a door
  • all of the cameras which can view the area immediately adjacent this door will be associated with this switch, and the coordinates of a point on the secured side of the door may be identified as the target coordinate.
  • the system Upon occurrence of an alarm, at 490, the system will mark each of the cameras associated with this alarm, at 492, and will set the target coordinates at 494.
  • the association of cameras to each alarm need not be explicit; the target coordinate could be provided to the loop 420-440 to determine the cameras associated with the alarm.

  • the user may be provided a view of the image from the selected camera in another region, or window, on the display screen 180, as shown at 510 in Fig. 5.
  • the system provides the user the ability to point within the displayed image 510 to redirect the selected camera. Pointing, for example to the person 51 1 in the image, effects a movement of the camera, via the control 130, so as to center the person 511 in the image.
  • Zoom-in and zoom-out options will also be provided, using for example, different button switches on the mouse 171.
  • a view from another camera which also includes the point P, or a camera viewing an area in the proximity of the point P can also be displayed on the display screen 180, at 520, and the operator has the option of selecting a point within that region for camera selection and adjustment.

Displaying this span of view on the graphic representation of the secured area provides the operator with a reference base upon which to more easily assess the image being presented by the camera.

Abstract

Dans un système de caméras multiples (101-103), les éléments vus par une pluralité de caméras sont mis en correspondance de façon à donner une représentation graphique. Un utilisateur désirant voir une zone située à l'intérieur du système pointe sur la position correspondante à l'intérieur de la représentation graphique par l'intermédiaire d'une interface utilisateur (171). Le dispositif détermine laquelle des caméras (101-103) contient le point indiqué dans son champ de vision et affiche la sortie de ladite caméra sur un moniteur (150). Si plus d'une caméra contient ledit point dans son champ de vision, l'utilisateur peut choisir quelle caméra utiliser pour l'affichage. Dans un autre mode de réalisation, des alarmes (111, 112) sont disposées à l'intérieur de la surface surveillée. Le déclenchement d'une alarme (111, 112) équivaut au pointage d'un utilisateur sur l'emplacement de l'alarme dans la représentation graphique.
