[0001] The present invention relates to a system for controlling illegal collection of image information,

More particularly, the present invention relates to a system and method for acquiring a plurality of region images of all regions photographed by a PTZ (Pan Tilt Zoom) network camera, and an arbitrary region out of all the regions in real time A plurality of region images are synthesized by a server using a plurality of photographed images to generate a first full area image and a coordinate value is given thereto and the coordinate values and the up / down / down / down angle of the PTZ (Pan Tilt Zoom) Generates a second overall area image in which the left / right rotation angle / magnification is mapped, sets a surveillance area on the generated second full area image, and generates a notification event when the plurality of shot images are out of the surveillance area And more particularly, to a system for illegally collecting image information.

Conventionally, the CCTV or camera used for surveillance purpose has a tendency to use PTZ (Pan Tilt Zoom) network camera which has a high quality and a wide shooting range like Full HD recently because the quality of the captured image is low.

In addition, PTZ (Pan Tilt Zoom) network cameras have been developed to capture high-quality video images even in bad weather conditions such as nighttime and bad weather conditions. Furthermore, the PTZ (Pan Tilt Zoom) Many techniques for detecting, tracking, and classifying objects and notifying users of events through analysis have been developed.

Various types of cameras including the conventional CCTV and PTZ (Pan Tilt Zoom) network cameras are regulated by the Personal Information Protection Act. Particularly, in accordance with Article 25 (5) of the Personal Information Protection Act ), "The operator of the image information equipment shall not arbitrarily manipulate the image information processing equipment for purposes other than the purpose of installation of the image information processing equipment, or shine it elsewhere." The penalty for this is that a prison sentence of 3 years or less Or a fine of not more than 30 million won.

However, even if the PTZ (Pan Tilt Zoom) network camera installed in the field was installed for public purposes such as crime prevention and facility management, there was no practical technical alternative to control the image shooting operation deviating from the authorized installation purpose.

On the other hand, PTZ (Pan Tilt Zoom) network camera itself has a function of limiting the angle of view, but it is fundamentally limited to block the act of shooting by the authorized person there was.

In addition, when the angle of view of the PTZ (Pan Tilt Zoom) network camera is set, if the applied range of the camera is scattered within the area that one camera can see, it is impossible to clearly determine the category of the non-objective photographing.

Best Mode for Carrying Out the Invention Hereinafter, a configuration and an operation of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of a video information irregularity collection control system according to an embodiment of the present invention. The video information irregularity collection control system includes a PTZ (Pan Tilt Zoom) network camera and a server 200.

More specifically, the PTZ (Pan Tilt Zoom) network camera generates a plurality of region images of all the regions photographed, and photographs any one region of all the regions in real time to generate a plurality of photographed images.

All of the above-mentioned areas are 360 ° rotation (vertical angle with left and right rotation angle) while moving up and down, which is one of the features of PTZ (Pan Tilt Zoom) network camera 100, And the plurality of region images are photographed by the server 200 to generate one image, i.e., a first full area image.

2, (a) shows a plurality of region images for all regions that can be captured by the PTZ (Pan Tilt Zoom) network camera 100, (PTZ) network camera among the first full area images, the server 200 generates a first full area image using the plurality of area images, and FIG. 2 (b) Is a real-time photographed area by the camera 200. A region for real-time photographing soon becomes a surveillance region to be monitored, and a plurality of photographed images are generated by photographing the surveillance region.

The server 200 combines the plurality of region images to generate a first full area image and provides coordinate values to the coordinate values and the vertical angle / left / right angle of the PTZ (Pan Tilt Zoom) Generates a second full area image in which the rotation angle is mapped, sets a surveillance area on the generated second overall area image, and generates a notification event when the plurality of shot images deviate from the surveillance area.

That is, in order to determine whether the PTZ camera 100 continuously monitors the surveillance area to be monitored by the PTZ camera 100, (B ', C', D ', E', F ') from the PTZ (Pan Tilt Zoom) network camera 100 because the first full area image 3, and so on.

That is, the second full-area image is mapped to the PTZ (Pan Tilt Zoom) network camera 100, and thus the direction of the PTZ (Pan Tilt Zoom) network camera 100 is changed, that is, 2 It is possible to confirm that the photographed image appearing in the entire area image has been changed, and thereby, whether or not the photographed image has deviated from the set surveillance area.

In addition, the photographed image is generated by photographing the surveillance region in real time. When the photographed image photographed in real time leaves the surveillance region within a set error range, the server 200 generates notification data .

The notification data is generated in order to control the fact that the notification data has departed from the surveillance area because it captures an image outside the permitted area and includes an act of collecting image information illegally in addition to the purpose.

1, the server 200 includes a receiving unit 210, an overall area image generating unit 220, a mapping unit 230, a setting unit 240, and an application unit 250 It is preferable that the receiving unit 210, the entire area image generating unit 220, the mapping unit 230, the setting unit 240, and the application unit 250 further include a log generating unit 260.

In more detail, the receiving unit 210 of the server 200 receives the plurality of region images and receives a plurality of photographed images.

The plurality of region images are images of all regions photographable at a point where the PTZ (Pan Tilt Zoom) network camera 100 is installed, and the plurality of region images may be used to generate one first full region image using the plurality of region images will be.

The plurality of photographed images indicate whether the PTZ (Pan Tilt Zoom) network camera 100 is monitoring the set surveillance region and that the surveillance region is deviated from the surveillance region. That is, It is intended and can be exploited by such intent to commit crime, especially personal privacy invasion.

The overall area image generator 220 of the server 200 synthesizes the plurality of received area images to generate a first full area image and gives coordinate values thereto.

For example, as shown in FIG. 3, the maximum area that can be photographed while the PTZ (Pan Tilt Zoom) network camera 100 moves 360 degrees (right and left) ), The image is rotated 360 degrees as in the case of B while moving up and down (Tilt) like A to generate an image similar to B ', and rotated 360 degrees as in C to generate C' And B ', C', D ', E', and D 'are repeated to reproduce the same image as D, E, F, F 'to combine the plurality of region images to generate one first full region image.

At this time, images overlapping and overlapping between B 'and C' are synthesized by an image synthesis method. Since this image synthesis method can be applied to various known technologies, further explanation is omitted.

The mapping unit 230 of the server 200 maps the coordinate values of the first full area image given the coordinate values and the vertical angle / left / right rotation angle / magnification of the PTZ (Pan Tilt Zoom) network camera 100 And generates a second full area image.

For example, as shown in FIG. 3, the PTZ (Pan Tilt Zoom) network camera 100 operates up and down like A, and the up and down movement is the vertical angle of the PTZ (Pan Tilt Zoom) And C, D, E, and F are the left and right rotational angles, respectively, and are mapped to the coordinate values of the first full area image according to the up and down angles and the left and right rotational angles.

That is, the pan shown in FIG. 4 has a value of 30 to 320, the tilt has a value of 10 to 90, and the zoom has a pan tilt zoom (PTZ) So as to have a vertical angle and a left-right rotation angle and magnification of the camera 100.

The setting unit 240 of the server 200 sets a surveillance region on the generated second full area image.

For example, as shown in FIG. 4, the setting unit 240 may be implemented by software. The value of the pan is 30 to 320, the value of the tilt is 10 to 90, the value of the zoom If it is set to 1, it is determined whether or not the captured image captured in real time by the PTZ (Pan Tilt Zoom) network camera 100 according to the set Pan, Tilt, .

Also, the setting unit 240 sets an error range in the monitoring area.

The reason for setting the error range is that the PTZ (Pan Tilt Zoom) network camera 100 may fluctuate due to a change in weather such as wind, rain, snow, and hail, And the error range.

The application unit 230 of the server 200 generates an alarm event when the plurality of captured images are out of the surveillance area.

That is, as mentioned above, the application unit 250 does not arbitrarily manipulate the image information processing device or illuminate the other area by the method, so that the image taken on the image of the second full area is not the coordinate value And to generate an alarm event when it is diverted.

For example, if the surveillance region to be monitored by the PTZ (Pan Tilt Zoom) network camera 100 is an edge-connected region such as H, I, J, and K shown in FIG. 5, H, I, , And the monitoring area is shifted from the monitoring area by the change of the coordinate value when the monitoring area is changed to the monitoring area H ', I', J ', K of the first captured image including the real time photographing.

In addition, when the notification event is generated, the application unit 250 generates a control signal for blocking the photographing of the PTZ camera 100 and a control signal for activating an event pop-up window having information that the surveillance area is out of sight.

In addition, when the captured image leaves the surveillance region, the application unit 250 remotely controls the surveillance image to monitor the surveillance region by inputting the pan, tilt, and zoom values corresponding to the surveillance region.

In other words, the fact that the photographed image has deviated from the surveillance region means that the pan, tilt, and zoom values of the PTZ (Pan Tilt Zoom) network camera 100 have been changed, and that the pan, tilt, Remote control.

As a result, the remote control is controlled by the mechanical movement and the software operation of the PTZ (Pan Tilt Zoom) network camera 100 in the up-and-down angle, the left-right rotation angle, and the magnification.

The log generation unit 260 of the server 200 includes a log in which a surveillance area departure cause is recorded when the photographed image leaves the surveillance area.

At this time, the captured image is a sort of image taken in a type of Snap Shut, and the image includes a log.

The fact that the PTZ (Pan Tilt Zoom) network camera 100 deviates from the monitoring area coordinate value means that the PTZ (Pan Tilt Zoom) network camera 100 detects a movement .

At this time, the PTZ (Pan Tilt Zoom) network camera 100 includes a log for analyzing what causes the movement, and it is intended to control whether or not the image information is illegally collected through the log to be included.

For example, the movement of the PTZ (Pan Tilt Zoom) network camera 100 may be caused by an external physical force, for example, a meteorological phenomenon such as rain or snow, or a force by a person, For example, a manager who manages a PTZ (Pan Tilt Zoom) network camera 100.

At this time, if the photographed image is moved due to an external physical force, the log of the movement of the present invention log generation unit 260 is generated and included if the photographed image is moved by a meteorological phenomenon such as rain or snow, No other logs will be generated.

However, in the case of the administrator who manages the PTZ (Pan Tilt Zoom) network camera 100, if the photographed image is deviated from the surveillance area by the system operated by the administrator, And a log indicating whether or not the PTZ (Pan Tilt Zoom) network camera 100 is connected is included in the captured image.

In this way, the image log has a history of the log and it is possible to judge whether or not the image information is unclearly collected through the history of the log.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to cover further limitations anddisclamping the scope of the present invention as defined by the appended claims. It is not.

Therefore, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
