Description

Monitoring Camera Apparatus Unifying Panorama Camera and Pan-Tilt-Zoom Camera and Remote Monitoring System Employing the Same}

The present invention relates to a television camera device, and more particularly, to a hybrid monitoring camera device having a plurality of cameras. In addition, the present invention relates to a remote monitoring system employing such a camera device.

Security / surveillance systems using surveillance camera devices are widely used for access control and crime prevention. The installation of such security / surveillance systems is spreading in banks, military facilities, other public facilities or business buildings requiring security, and in general roads and residential areas.

Although various types of surveillance camera devices are used, one of the most widely used camera devices at the time of the present application is a pan capable of horizontal rotation (i.e. panning) and vertical rotation (i.e. tilting) and zooming up / down. Pan-Tilt-Zoom (PTZ) camera device. According to the PTZ camera device, the horizontal and vertical rotation of the camera and the zoom up / down can be controlled remotely, so that the remote operator can change the surveillance area or monitor only a specific target as needed. .

However, since the angle of view of the lens employed in the PTZ camera device is not wide, a blind spot that the camera device cannot capture may occur depending on the monitoring direction set by the operator. In particular, when a user zooms in on a lens and drives a panning and tilting mechanism to track and monitor a specific target, there is a problem that monitoring is impossible except for the surroundings of the tracking target.

In order to expand the surveillance range, there is a fixed camera device that secures a panoramic image by employing an ultra wide-angle lens such as a fisheye lens.However, in the case of a camera device using a fisheye lens, the image to be photographed is rounded, and the image is not only severely distorted. At the edges, things are difficult to identify. Accordingly, the fisheye lens type camera can only be used to examine the overall situation, and is rarely used in the PTZ camera device.

Attempts have been made to combine surveillance for a wide area with tracking for a specific object by combining a camera for acquiring a panoramic image and a PTZ camera for intensive surveillance.

For example, according to the invention described in Korean Patent Laid-Open Publication No. 2004-0031968 (name of the invention: an intruder tracking device using a double camera and a method thereof), a first camera using a fisheye lens, a convex mirror, or a convex mirror / concave mirror combination is provided. By taking a panoramic image of the indoor or surveillance target area, if an intruder occurs in the surveillance target area, and automatically detects the moving position of the intruder and captures the image of the intruder while tracking the intruder by the second camera.

By the way, the dual camera device described in this document is very complicated in structure, as the inventors intended, so that the processing and assembling work is large. Furthermore, since the first camera is provided at the bottom center of the dual camera device, the first camera obstructs the field of view of the second camera or hinders the up, down, left and right movements of the second camera. Accordingly, when the intruder is located below the center of the dual camera device, it is impossible to accurately photograph the intruder with the second camera.

Patent Publication No. 2005-0103597 (name of the invention: a surveillance system using a real-time panoramic video image and a method of controlling the system) installs a plurality of component cameras on the outer circumferential surface of the support bar and integrates a PTZ camera on the top of the support bar.

However, in another embodiment of the present invention, the support may be rotated by a motor. In particular, the driving of such a motor may be remotely controlled in a manner similar to the pan / tilt control for the second camera unit.

Meanwhile, in the above description, the panning / tilting driving of the camera apparatus is described based on the embodiment in which the panning / tilting driving is automatically performed based on the motion detection in the camera apparatus. This may be done. It goes without saying that the remote monitoring apparatus may pan / tilt / zoom by detecting movement in the panoramic image.

On the other hand, in the above description has been described with reference to the embodiment in which the control device selects the panoramic image portion in the second image, the selection of the image may be made in the camera device. In such a case, a control signal for selecting the image of the image may be provided to the camera device from the control device.

Therefore, the embodiments described above are to be understood in all respects as illustrative and not restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
