Description

Technical Field [0001] The present invention relates to a video surveillance area setting system,

The present invention relates to a video surveillance area setting system and method.

A general physical security system installs a CCTV in the area to be monitored and attaches a sensor to identify an event such as an intrusion. In order to check the surrounding environment, the manager controls the PTZ (Pan Tilt Zoom) camera and manages the CCTV and sensor installed directly to provide the service.

In case of the intelligent surveillance system, the event area should be set once again after the above installation process. Then, an intelligent video surveillance system that utilizes the video data of the designated surveillance area and the sensor data is constructed, and the service can be provided to the customer.

Also, when the object disappears from the camera, the object information must be transmitted to the next CCTV. Here, the location of the next CCTV can be provided in advance when the CCTV is installed and the tracking service can be provided by transmitting the object information only on the assumption that the database is interlocked.

However, the above-described conventional technique requires the intervention of the installer when the camera is installed, and the accuracy of the intelligent surveillance is different according to the know-how installed by the installer. Further, there is a disadvantage in that it is difficult to provide object information to the next CCTV unless the location information is grasped and installed in a geographic information system (GIS) server in advance.

And, if there is no dedicated server such as VMS (Video Management System) or VA (Video Analytics), it is difficult to collect multiple CCTVs, sensors and analysis data. Therefore, it is impossible to provide the intelligent physical security service, and when the network is not connected, the utilization of the intelligent service is deteriorated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

Hereinafter, a video surveillance system and method according to an embodiment of the present invention will be described with reference to the drawings. In the embodiment of the present invention, a plurality of management servers and a video surveillance server are referred to as video surveillance systems, but the present invention is not limited thereto.

1 is an exemplary diagram illustrating an environment in which a video surveillance system according to an embodiment of the present invention is applied.

1, the management server 100 is interlocked with at least one CCTV 400 or IoT terminal (for example, a sensor, etc.) 500 in order to monitor an arbitrarily set one monitoring zone . In the embodiment of the present invention, the management server 100 is described as being installed in a control center (not shown) that controls a monitoring area that is set arbitrarily, but is not limited thereto. And the IoT terminal 500 may not necessarily be installed.

One management server 100 controls and manages one or more CCTVs 400 in cooperation with at least one CCTV 400 installed in the monitoring area. In addition, the management server 100 transmits a surveillance image (hereinafter, referred to as 'video') transmitted from the CCTV 400 to the video surveillance server 200 connected thereto. And transmits the control signal to the CCTV 400 based on the analysis information of the image transmitted from the video surveillance server 200.

At least one management server (100) interlocks with one video surveillance server (200). Here, the video surveillance server 200 is described as an example in which the video surveillance server 200 is installed in a central control center (not shown), but is not limited thereto.

The video surveillance server 200 analyzes the video transmitted from the management server 100 and extracts objects in the video captured by the CCTV 400. [ Then, the video surveillance server 200 compares the extracted objects with previously stored pattern information to check whether the object corresponds to the CCTV.

Here, the pattern information is a pattern of various shapes of CCTVs. The method of comparing the object with the object extracted from the pattern information by the video surveillance server 200 can be performed by various methods. Therefore, the present invention is not limited to any method.

That is, the video surveillance server 200 analyzes and processes images collected by at least one CCTV in at least one surveillance zone. The video surveillance server 200 provides analysis information on the analyzed video to the terminal 300 in cooperation with the terminal 300. At this time, the terminal 300 may be a terminal of a user or a terminal of a controller working at a control center.

The video surveillance server 200 analyzes the video and extracts information of an object included in the video. At this time, the object may be an object to be monitored by a general control such as a person, an automobile, or an animal, or may be another CCTV adjacent to the CCTV. In order to extract other CCTV objects, the video surveillance server 200 stores pattern information on various types of CCTVs.

Also, the video surveillance server 200 transmits the extracted object information to the at least one management server 100 or the terminal 300 that interlocks with the object of general control. The extracted object information includes the characteristic information of the object, for example, the color of clothing, the key, the characteristic to be worn, etc. worn by a person, and the video surveillance server 200 extracts the information The method is already known, and a detailed description thereof will be omitted in the embodiment of the present invention.

In addition, when the CCTV server 200 extracts the CCTV as an object, the video surveillance server 200 provides the analysis information to the management server 100 including the PTZ setting value information of the CCTV. This will be described in detail later. In the embodiment of the present invention, the video surveillance server 200 is implemented as a video surveillance as a service (VSaaS) platform, but the present invention is not limited thereto.

When a plurality of CCTVs 400 are installed for the first time, the management server 100 transmits the default PTZ set values and CCTV identification information, which are set as defaults, to the CCTV. Based on the CCTV control signal transmitted from the management server 100, the PTZ setting value is adjusted.

In addition, the CCTV 400 transmits the image of the objects to the management server 100. Here, the photographed image may be transmitted to the management server 100 in real time or may be transmitted to the management server 100 in a preset period. When the CCTV 400 receives an image acquisition control signal from the management server 100, the CCTV 400 transmits the captured image to the management server 100 in real time.

The IoT terminal 500 is installed in the house and transmits an event occurrence signal to the management server 100 when an intruder enters the surveillance area of the IoT terminal 500, for example. If the IoT terminal 500 includes a function of collecting images, the collected images are transmitted to the management server 100. Although the IOT terminal 500 and the management server 100 are connected to each other through a personal area network (PAN), the present invention is not limited thereto.

Here, the management server 100 interworking with at least one CCTV in an arbitrary monitoring area will be described with reference to FIG.

2 is a structural diagram of a management server according to an embodiment of the present invention.

2, the interface 110 of the management server 100 is interlocked with the CCTV 400, the IOT terminal 500, and the video surveillance server 200, and is preset in the CCTV from the first installed CCTV And receives the CCTV information including the identification information of the CCTV together with the default PTZ setting value.

Then, the management server 100 sets a surveillance area of the CCTV installed first. In order for the management server 100 to set the surveillance area of the CCTV, the CCTV captures the default surveillance area based on the preset default PTZ setting value. The photographed image is transmitted to the video surveillance server 200 through the interface 110, and the video surveillance server 200 extracts predetermined objects such as a window or an entrance from the video.

The processor 120 of the management server 100 sets a surveillance area such as a line invasion or an area invasion according to the object based on the extracted information about the specific objects extracted by the video surveillance server 200. [ The set monitoring area is stored in the memory 130 together with the CCTV information of the CCTV. Here, the method of setting the surveillance region can be performed by various methods, so that the detailed description will be omitted in the embodiment of the present invention.

In addition, the management server 100 transmits the surveillance image transmitted from the CCTV to the video surveillance server 200 through the interface 110 after the surveillance area is set. This is to establish the CCTV relationship for newly installed CCTVs. Assuming that an object is monitored in one CCTV relation, if the object is out of the CCTV surveillance area, the CCTV relation is a procedure for searching for a neighboring CCTV to be continuously monitored.

To this end, when the CCTV is installed in the monitoring area for the first time, the management server 100 transmits the collected CCTV image to the video surveillance server 200, and requests the video monitoring server 200 to analyze whether there are objects judged as CCTV in the video. When the management server 100 receives the object extraction information indicating that there is an object judged to be a CCTV from the video surveillance server 200, the management server 100 sequentially controls the change of the PTZ setting values to all CCTV interlocked with the management server 100 And transmits a control signal.

Then, the PTZ setting value is changed based on the control signal, and the CCTV receives the image of the moving CCTV, and transmits the received video to the video surveillance server 200. The analysis information is received from the video surveillance server 200, and the information about the neighboring CCTVs to be overlapped with the surveillance region of the CCTV that collected the video based on the received analysis information is grouped and stored in the memory 130 .

Also, the management server 100 transmits a control signal for controlling the terminal to the IoT terminal 500 through the interface 110 to collect the identification information and the position information of the IoT terminal 500.

The management server 100 sets a region of interest (RoI) of each CCTV when the setting of the CCTVs 400 is completed. In the past, CCTV installers and administrators need to work with installers, such as creating a line invasion event and creating an area invasion event, by visually confirming it directly.

However, in the embodiment of the present invention, when the CCTV 400 detects a door, a window, a POS (Point of Sales) device or the like as an object in the default surveillance area at a location where the CCTV is installed, The line intrusion zone or zone intrusion zone is set appropriately. The method of setting the line-invading area or the area-invading area can be performed by various methods, so that the detailed description will be omitted in the embodiment of the present invention.

A method of setting a video surveillance area for the management server 100 to monitor an object using the CCTV 400 in the above-described environment will be described with reference to FIG.

3 is a flowchart illustrating a video surveillance area setting method according to an embodiment of the present invention.

It is assumed that at least one CCTV is installed in an arbitrary control area. Then, as shown in FIG. 3, the management server 100 first sets CCTV through information transmission / reception with the CCTV 400 (S100). In the CCTV setting step, the default PTZ setting value of each newly installed CCTV 400 and the identification information assigned to each CCTV are transmitted to the management server 100 to inform that the new CCTV is installed in the control area.

If CCTV is set in step S100, the management server 100 sets a monitoring area for each CCTV (S200). Here, the CCTV setting step in steps S100 and S200 and the step of setting the surveillance area will be described first with reference to FIG.

4 is a flowchart illustrating a CCTV setting method according to an embodiment of the present invention.

As shown in FIG. 4, it is assumed that the first CCTV 400-1 and the second CCTV 400-2 are installed in the control area. Then, the first CCTV 400-1 and the second CCTV 400-2 transmit the CCTV information including the default PTZ setting value set in each CCTV and the respective identification information to the management server 100 (S101, S102).

The management server 100 stores the received CCTV information through steps S101 and S102 (S103). After transmitting the CCTV information, the first CCTV 400-1 and the second CCTV 400-2 transmit the images photographed in the preset default monitoring area to the management server 100 (S201, S202 ). Here, the method of presetting the default surveillance area in the CCTV or the method of transmitting the image of the default surveillance area to the management server 100 can be performed by various methods. Therefore, in the embodiment of the present invention, .

The management server 100 transmits the image received in steps S201 and S202 to the video surveillance server 200 (S203). The video surveillance server 200 analyzes the received video image and determines whether there are pre-set objects such as a door, a window, and a POS device in the video (S203). Here, a method of analyzing the image by the video monitoring server 200 to determine whether there are objects can be variously performed, and is not limited to any one method.

The video surveillance server 200 transmits the analyzed video information to the management server 100 (S205). The video information includes the presence or absence of preset objects and the position information of the object if the object exists.

Based on the analysis information received in step S205, the management server 100 detects where the objects are located (S206), and sets a monitoring area based on the position of the detected objects (S207). Here, the surveillance area can be set in various ways, such as a line-invasion area or an area-invasion area, depending on the types of objects photographed by the image, and the setting method is not limited to any one method.

After the monitoring area of the newly installed CCTV and the corresponding CCTV is set through the above procedure, the management server 100 sets a monitoring area for each CCTV according to step S200. (S300). The CCTV relation setting method in step S300 will be described with reference to FIG. In FIG. 5, an example in which the first CCTV 400-1 collects images and finds a neighboring CCTV for the first CCTV 400-1 and establishes a relationship is described.

FIG. 5 is a flowchart of a CCTV relation setting method according to an embodiment of the present invention.

5, when the first CCTV 400-1 collects images photographed in the control area and transmits them to the management server 100 (S301 and S302), the management server 100 transmits the images captured by the video surveillance server 200) (S303).

The video surveillance server 200 analyzes the video received in step S303, and determines whether there is an object of the CCTV type among the video objects (S304). To this end, the video surveillance server 200 stores pattern information on various types of CCTV, and compares the image of the extracted objects with the stored pattern information in step S304.

Then, an object estimated by the CCTV among the objects in the video is detected according to the comparison result. The method of detecting the object estimated by CCTV by comparing the image of the extracted objects with the pattern information can be performed by various methods, and therefore, the present invention is not limited to any one method.

If there is an object estimated to be a CCTV in the video, the video monitoring server 200 generates object extraction information and transmits the object extraction information to the management server 100 (S305). When the management server 100 receives the object extraction information in step S305, the management server 100 generates a control signal for adjusting the PTZ values of the CCTVs other than the first CCTV 400-1, that is, the second CCTV 400-2 To the second CCTV 400-2 (S306, S307).

Since the first CCTV 400-1 and the second CCTV 400-2 are described only in the embodiment of the present invention, the management server 100 generates only a control signal for controlling the second CCTV 400-2 As an example. However, if it is assumed that a plurality of CCTVs are installed in the control area where the first CCTV 400-1 is installed, each CCTV sequentially generates and transmits control signals to change the PTZ set values.

In step S308, the second CCTV 400-2 adjusts the PTZ value based on the control signal received in step S307, and moves the camera lens up, down, left, and right by the PTZ set value included in the control signal centered on the camera lens. At the same time, the first CCTV 400-1 continuously collects the images including the objects and transmits them to the management server 100 (S309, S310).

The management server 100 delivers the image received in step S310 to the video surveillance server 200 (S311). The video surveillance server 200 analyzes the image received in step S311 (S312), and transmits the analyzed information to the management server 100 (S313). The analysis information transmitted to the management server 100 includes PTZ setting value information about objects in which the motion has occurred.

That is, when it is determined that there is an object in which motion occurs, the video surveillance server 200 moves the image so that the object is located at the center of the screen. Then, the first CCTV 400-1 extracts the PTZ value when viewing the object in which the motion occurs. If no motion has occurred in any of the objects, the analysis information does not include the PTZ value.

Based on the analysis information received in step S313, the management server 100 determines whether there is a CCTV in which motion has occurred in the extracted CCTV (S314). If the analysis information does not include the PTZ value, it is determined that the first CCTV 400-1 and the second CCTV 400-2 are not adjacent CCTVs, Terminate the relationship setup procedure.

However, if it is determined that the CCTV movement has occurred based on the analysis information, the management server 100 transmits a control signal for changing the PTZ value of the first CCTV 400-1 to the first CCTV 400-1 (S315). This is because, even if the first CCTV 400-1 captures moving CCTV in the process of capturing an image, the corresponding CCTV may be another CCTV than the second CCTV 400-2.

Accordingly, it is determined whether the first CCTV 400-1 is moved and the first CCTV 400-1 moving on the image captured by the second CCTV 400-2 is photographed. In step S315, the first CCTV 400-1 controls the PTZ set value to move the camera of the CCTV. At the same time, the second CCTV 400-2 captures an image and transmits it to the management server 100 (S315 , S316). The management server 100 transmits the video received through the second CCTV 400-2 to the video surveillance server 200 in step S316 (S317).

The video surveillance server 200 analyzes the image received in step S317 and transmits the analyzed information to the management server 100 (S318). The analysis information transmitted to the management server 100 includes the PTZ setting value information of the object where the motion occurred when there is an object in which the motion occurred.

The management server 100 determines whether there is CCTV moving based on the analysis information received in step S318, and ends the relationship setting between the first CCTV 400-1 and the second CCTV 400-2. However, if the movement of the CCTV is confirmed based on the analysis information, it is confirmed that the first CCTV 400-1 and the second CCTV 400-2 are adjacent CCTVs.

Therefore, the management server 100 stores the correlation information of the CCTV and sets the relation between the first CCTV 400-1 and the second CCTV 400-2 (S320). That is, in step S313, the PTZ setting value included in the analysis information is stored as a PZT setting value for the second CCTV 400-2 as shown in Table 1.

PZT setting value CCTV identification information 20.0.0 Second CCTV 40.0.0 Third CCTV 90.0.0 Fourth CCTV

In the embodiment of the present invention, only the angle information of the first CCTV 400-1 when viewing the adjacent CCTVs is shown, but the PTZ setting values of the adjacent CCTVs are stored for all the CCTVs in the control area.

Taking the second CCTV as an example, when the first CCTV 400-1 sets its PZT set value to 0.0.0, the PTZ setting value of the first CCTV 400-1 is set to 20.0. 0, the second CCTV 400-2 is located at the center of the image.

An example of the case where the second CCTV 400-2 is photographed on the screen in the image captured by the first CCTV 400-1 and analyzed by CCTV will be described first with reference to FIG.

Figure 6 is an illustration of an image capture of a related CCTV in accordance with an embodiment of the present invention.

6A, when the management server 100 delivers the video received from the first CCTV 400-1 to the video surveillance server 200, the video surveillance server 200 transmits the video And extracts all objects appearing in the image. In order to confirm whether or not the extracted object is CCTV, the video surveillance server 200 uses various pre-stored CCTV pattern information as shown in FIG. 6 (b). In FIG. 6 (b), the dome camera and the housing integrated camera are shown as an example, but various camera patterns such as a PTZ camera and an infrared camera may be stored.

When the CCTV relationship is established, the CCTV 400, the management server 100, and the video surveillance server 200 monitor the objects through interworking as shown in FIG. 3 (S400). A video surveillance method of an object will be described with reference to Fig.

7 is an exemplary diagram illustrating an object monitoring method according to an embodiment of the present invention.

In FIG. 7, three monitoring areas 700-1 to 700-2 are set, and management servers 100-1 to 100-3 for managing CCTVs are located in each monitoring area. Each of the management servers 100-1 to 100-3 cooperates with the video surveillance server 200 and the video surveillance server 200 provides the control information to the terminal 800 in the control center.

As shown in FIG. 7, it is assumed that the object 600 is located in the first monitoring area 700-1, and the CCTV that has captured the image of the object 600 is the first CCTV 400-1. It is assumed that the first CCTV 400-1 and the second CCTV 400-2 are tied to the adjacent CCTV and the second CCTV 400-2 is connected to the third CCTV 400-3 Is set.

And CCTVs may be established not only with CCTVs installed in each monitoring area, but also with CCTVs installed in other monitoring areas. For example, the third CCTV 400-3 may establish a CCTV relationship with the fourth CCTV 400-4 of the adjacent second monitoring zone 700-2.

Even if the object 600 moves out of the surveillance area of the first CCTV 400-1 and enters the surveillance area of the second CCTV 400-2, the first management server 100-1 transmits the first CCTV 400- 1 and the second CCTV 400-2 are adjacent CCTVs. Accordingly, the first management server 100-1 can receive the image information from the second CCTV 400-2, and can continuously track the object organically to move the object 600 to collect the object information.

At this time, in a process of tracking the object 600 to which the second CCTV 400-2 moves, an area that can not be photographed may occur. In this case, the first management server 100-1 can issue a control command so that the third CCTV 400-3 set as a relation monitors the corresponding area.

Here, the movement direction of the object 600 is determined by analyzing the video by the video surveillance server 200. Since the method of grasping the moving direction of the object 600 can be performed through various methods, the present invention is not limited to any one method.

In addition, the video surveillance server 200 transmits analysis information obtained by analyzing the object 600 to the management servers 100-1 to 100-3. This is for the purpose of enabling the controller to selectively recognize objects with high accuracy by providing the detection results of the objects on the terminal 800 of the control center on the basis of the object 600 information in order of accuracy. Here, the method of generating the analysis information of the objects 600 by the video surveillance server 200 may also be performed through various methods, so that the present invention is not limited to any one method.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
