Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The pan / tilt / zoom function integrated surveillance camera used in the present invention includes a pan / tilt / zoom camera 100 having a lens coupling part 110 at the front end, as shown in FIGS. 1 and 2; And a wide-angle lens 120 coupled to the lens coupling unit 110.

The configuration of the lens coupling unit 110 may vary according to one of ordinary skill in the art according to the exemplary embodiment, but the female coupling unit and the male screw unit are formed as shown in the drawing, and the wide-angle lens 120 is 180. It is preferable to use a camera having a wide angle of view, such as a fisheye lens or a 360 degree mirror lens.

On the other hand, the solid line A in Fig. 2 shows the imaging angle when the 180 degree mirror lens is configured, and the dotted line B shows the imaging angle when the 360 degree mirror lens is constructed.

In addition, the surveillance system according to the present invention, as shown in Figure 3, through the pan / tilt / zoom camera 100 is integrally coupled to the wide-angle lens 120 to view the omni-directional (360 degree) remote image of the surveillance area Camera device unit 200 for imaging; An image signal processing unit 300 for converting the distorted long distance image signal captured by the camera apparatus 200 into image data; Select an unwrapping region of the image-distorted image data of the image signal processing unit 300 to make a region of interest (ROI), and convert a required curved region of the ROI into a planar image by a lookup table. A central processing unit 400 configured to display the image on a monitor and restore the planar image to an original image through an image calibration process to configure at least one monitoring screen; And an intensive monitoring unit 500 for enlarging a specific region through the pan / tilt / zoom camera 100 among the images restored by the central processing unit 400 and configuring and displaying the intensive monitoring enlarged screen. Is done.

That is, as shown in (a) of FIG. 4, the camera device 200 is a remote image of a road, for example, a road of hundreds of meters or more, through a camera means equipped with a 180 degree fisheye lens or a 360 degree mirror lens. The road situation (360 degrees) is captured and transmitted to the video signal processing unit 300. The video signal processor 300 converts the long distance video signal obtained from the distorted optical image captured by the camera apparatus 200 into image data and transmits the image data to the central processing unit 400.

In this case, the central processing unit 400 selects an unwrapping region of the image-distorted image data of the image signal processing unit 300 and shows a region of interest (ROI), as shown in (bc) of FIG. 4. This ROI is converted into a planar image through a lookup table as shown in FIG. 4 (d).

In addition, the central processing unit 400 converts the curved image (image) of the fan shape calculated through the above process into a planar image by a lookup table as shown in (d) of FIG. 4. .

The converted screen may be configured as a four-split screen as shown in FIG. 5, a three-split screen as shown in FIG. 6, or a two-split screen as shown in FIG. 7. It can vary depending on.

When the abnormal signal is generated or the movement of the abnormal object occurs while monitoring the monitoring area by configuring the screen as described above, the monitor can enlarge and monitor the specific part desired through the centralized monitoring unit 500.

In this case, the intensive monitoring screen may be configured as a general digital zoom screen for observing the image itself acquired through the wide-angle lens 120 by software magnification. As shown in FIGS. If you want to precisely observe, it is possible to configure a more precise screen through the optical zoom using the pan / tilt / zoom function of the pan / tilt / zoom camera 100.

This is because the conventional camera (panorama camera) that does not have the optical zoom function captures the entire area to be monitored and detects a specific point by only the digital zoom when motion is detected.The problem is that the pixels blur after zoom-in. In order to solve this problem, a separate pan / tilt / zoom (optical zoom) camera is used to monitor the magnified image.

However, the present invention is in contrast to this, and solved this with a pan / tilt / zoom camera combined with a wide-angle lens without the addition of a separate auxiliary camera, and a plurality of integrated surveillance cameras according to the present invention, if necessary according to the environment of the surveillance region. It can also be installed in a plurality of cameras, when configuring a plurality of display units such as a monitor, or a single display unit can be configured to selectively divide the screen or to enlarge a specific area to monitor.

On the other hand, the sensor unit 600 for detecting an abnormal signal appearing on the monitoring screen; And an alarm unit 700 expressing at least one of auditory and visual information when an abnormal signal is detected by the sensor unit 600. When the abnormal signal is detected through the sensor unit 600, the concentration unit is concentrated. The monitoring unit 500 may be configured to display an area where an abnormal signal is detected as a concentrated monitoring screen.

In the case of the sensor unit 600, the speed sensor may be used in a dynamic environment such as a road with a lot of motion, and the motion sensor, an infrared sensor, a voice sensor, etc., may be used in a static environment without motion. When the sensor unit 600 detects an abnormal signal, the sensor unit 600 delivers at least one of a visual or audio message such as an alarm or a siren to the monitor to make a quick response. On the screen, it can be configured to monitor and monitor the specific area where abnormal signal is detected.

On the other hand, when monitoring the image taken through the camera, it can be detected when the movement occurs in the monitoring screen itself, it can be configured to enable the movement detection without having a separate sensor.

In addition, when configuring the monitoring system using a pan / tilt / zoom integrated simultaneous monitoring camera according to the present invention can be configured to monitor the monitoring area by connecting to the monitoring system from one or more other remote sites in addition to the monitor.
