TECHNICAL FIELD [0001] The present invention relates to a CCTV integrated monitoring system for performing synoptic video surveillance with optimized object distribution,

The present invention relates to a method for implementing a CCTV integrated monitoring system that performs an object distribution-optimized synopsis video surveillance function, and more particularly, to a method and apparatus for monitoring objects included in a surveillance video shot through a CCTV in a synopsis manner This is a method for implementing a CCTV integrated control system that performs a synopsis video surveillance function that optimizes object distribution to analyze surveillance images by distributing and displaying each object according to the length of appearance time of each object displayed on the screen .

In recent years, CCTV (Closed Circuit Television) has been installed in alleyways, roads, and the like inside and outside buildings for the purpose of crime prevention, traffic information collection and monitoring. After an incident has occurred, a police officer or an administrator must check the monitor image on the monitor in order to confirm the incident. In this case, if you do not know the exact time of occurrence, it takes a long time to display the captured surveillance image from the beginning to the end of the monitor.

Therefore, conventionally, in order to shorten the monitoring time of the monitoring image, the monitoring image is monitored while being rapidly reproduced. In this case, an object passing quickly on the screen may be placed. In order to improve this, a method of adjusting the reproduction speed adaptively is used, but in this case, it takes a long time to check all the surveillance images.

In addition, a method of selecting only a core frame among the surveillance images and displaying it as a synopsis image is used. However, in this case, it is difficult to monitor the surveillance image due to missing objects included in the unselected frame.

Korean Patent Publication No. 10-2009-0117771 discloses a video indexing and video synopsis method and system. The synopsis method is a method of creating a shortened video by combining selected portions from a plurality of original images. This synopsis method compresses time so that a video clip can be viewed in a short time.

In the case of the above technique, one or more synopsis objects are sampled from each selected source object by time sampling using image points derived from a particular time period.

Each time for starting the display in the synopsis video for each synopsis object is determined so that at least three points each derived at each different time in the source video are simultaneously displayed in the synopsis video by displaying the selected synopsis object.

Therefore, it is not easy to monitor if a large number of objects are displayed at once or a lot of objects are displayed at a time depending on the number of objects appearing at a time. If the number of displayed objects is small, monitoring time is unnecessary do.

FIG. 2 is a flowchart illustrating a CCTV integrated control system according to an exemplary embodiment of the present invention. And FIG. 3 is a CCTV photographing screen for explaining a method of analyzing a surveillance image when implementing a CCTV integrated control system according to an embodiment of the present invention.

Referring to FIG. 1, the integrated control unit 120 extracts an object from a supervised image and analyzes the characteristic (S200). That is, referring to FIG. 2 and FIG. 3 to be described later, among the surveillance images transmitted from the plurality of CCTVs 100-1, 100-2, ..., 100-n, Extracts objects, and analyzes color, size, moving direction, and speed of each object.

Then, the appearance time until the extracted objects appear on the screen and disappear is analyzed (S210). At this time, if there is an object to be deleted (S220-Y), the object is automatically deleted so as not to be displayed on the synopsis image (S230). That is, if the appearance time of the objects is longer than the preset reference time, the object is not displayed on the synopsis image. Here, the reference time can be set and changed by the administrator.

When a synopsis display time setting command is input to the integration control unit 120 (S240-Y) and a setting command for setting the number of objects to be simultaneously displayed on the screen is inputted (S240-Y), the synopsis display time is adjusted (S270). That is, the synopsis display time is adjusted so that all the objects included in the surveillance image can be displayed as a synopsis image.

If the synopsis display time setting command is not inputted (S240-N), the synopsis display time is automatically set to the longest time among the appearance times (S250). That is, the appearance time of the object with the longest appearance time is set as the synopsis display time, and all the objects are arranged to be displayed on the screen within the set display time.

When a setting command for setting the number of objects to be simultaneously displayed on the screen is input (S240-Y), the synopsis display time is adjusted (S270).

Then, the integration control unit 120 divides the objects so that they are all displayed on the screen during the synopsis display time (S280), and displays the synopsis image on the screen (S290).

Through the above process, a synopsis image of the selected surveillance image can be generated and the surveillance image can be analyzed quickly and effectively.

2, the CCTV integrated control system of the present invention includes a plurality of CCTVs 100-1, 100-2, ..., 100-n, a CCTV network 110, an integrated control unit 120, A self network network 140, a first communication device 150, a second communication device 160, and a mobile communication network 170.

The plurality of CCTVs 100-1, 100-2, ..., and 100-n are connected to the integrated control unit 120 through the CCTV network 110 to capture a surveillance region to generate a surveillance image, (120).

The integrated control unit 120 stores surveillance images transmitted from the plurality of CCTVs 100-1, 100-2, ..., and 100-n or displays them on a screen. Also, a short synopsis image is generated by combining selected portions from the surveillance images photographed by the respective CCTVs (100-1, 100-2, ..., 100-n).

The surveillance image stored in the integrated control unit 120 or the synopsis image generated in the integrated control unit 120 may be transmitted to the police terminal 130 through the self network network 140 or may be transmitted to the police station terminal 130 through the mobile communication network 170 And transmitted to the first communication device 150 or the second communication device 160 owned by the general public.

Here, the self network network 140 may use a network connected between the integrated control unit 120 and a government office such as a police station. Also, the mobile communication network 170 can use a wireless Internet such as Wi-Fi or a mobile service network such as 3G, 4G, and LTE.

3 to 5, the operation of the integrated control unit 120 will be described in more detail.

Referring to FIG. 3, the integrated control unit 120 extracts the objects C1, C2, A1, A2, and H1 to H6 from the supervisory image selected by the administrator. In an exemplary embodiment of the present invention, a case where a surveillance image photographed through the first CCTV 100-1 is selected will be exemplified. Then, the characteristics including the color, size, moving direction, and speed of each extracted object are analyzed.

For example, the C1 object is blue, the size is 45 x 28 pixels, the direction of movement is analyzed to the right of the screen, and the speed is 60 Km / h. For the H1 object, the color is black, the size is 4X30 pixels, the moving direction is 2 o'clock direction of the screen, and the speed is 2.2Km / h. For the H6 object, the color is gray, the size is 5X27 pixels, the moving direction is 11 o'clock direction of the screen, and the speed is analyzed as 0.1 Km / h.

Also, the appearance time until each object appears on the screen disappears. 3, the appearance time of the C1 object is 2 seconds, the appearance time of the C2 object is 3 seconds, the appearance time of the A1 object is 8 seconds, the appearance time of the A2 object is 3 seconds, and the appearance time of H1 The time of appearance is 1 minute and 20 seconds for the object, the appearance time is 1 minute and 4 seconds for the H2 object, the appearance time is 1 minute and 3 seconds for the H3 object, the appearance time is 59 seconds for the H4 object, The time is 56 seconds, and for the H6 object, the time of occurrence is 5 minutes and 25 seconds.

Here, if the preset reference time of the appearance time is 3 minutes, the appearance time of the H6 object is 5 minutes and 25 seconds, which exceeds the predetermined reference time of 3 minutes. Therefore, H6 is automatically deleted so as not to be displayed on the synopsis image.

In the case of the parked vehicle shown in Fig. 3, even if it is recognized as an object, since there is no motion, it is not necessary to analyze the appearance time. Therefore, depending on the type of object, it can be automatically deleted so as not to be displayed on the synopsis image.

4 and 5 are views for explaining a method for generating a synopsis image for video surveillance in the integrated control unit included in the CCTV integrated control system according to an embodiment of the present invention. 4 and 5 illustrate the case where the objects (C3 to C12, A3, A4, H7, and H8) extracted from the surveillance images at other viewpoints photographed through the first CCTV in which the objects not shown in FIG. 3 are displayed are further included I will explain it.

Referring to FIG. 4, one minute and twenty seconds, which is the appearance time of the H1 object having the longest appearance time among the analyzed appearance times, is set as the display time of the synopsis image. And the rest of the objects are arranged so that they can all be displayed during the appearance time of the H1 object. At this time, objects with long appearance time are arranged first, and remaining empty time is filled with objects having short appearance time.

In other words, objects with long appearance times are arranged in the initial part of the synopsis image, and the rest of the objects are arranged at any time, regardless of the length. In addition, although the objects are arranged without gaps in FIG. 4, it is also possible to arrange and arrange gaps as necessary. In FIG. 4, the H1 object is displayed from the beginning to the end of the synopsis image.

If the synopsis display time is set to 2 minutes and 30 seconds by the administrator, each object is arranged in the order of appearance time as illustrated in FIG. In this case, the number of objects displayed in the synopsis image is reduced compared to the objects listed in FIG.

In FIG. 5, similarly, objects having a long appearance time are arranged in the initial portion, and the remaining objects are arranged regardless of the length of time at which the objects can be inserted. In addition, although the objects C7 to C12 and A3 are sequentially displayed in Fig. 5, a gap may be provided between the objects to arrange the objects in a synopsis image to be sparsely displayed.

Conversely, when the synopsis display time is set by the manager to a time shorter than the appearance time of the H1 object, the number of objects displayed in the synopsis image may be larger than the number of objects listed in FIG. That is, the number of objects simultaneously displayed in the synopsis image is changed according to the length of the synopsis display time. However, in this case, since two H1 objects are simultaneously displayed on the synopsis image, it may be difficult to read the images.

If the number of objects to be simultaneously displayed on the synopsis image is set by the administrator, the display time set so that each object is displayed on the screen in the order of the longest appearance time is adjusted.

For example, as shown in FIG. 4, when the synopsis display time is set to 1 minute and 20 seconds in the case of the H1 object, when the number of objects to be simultaneously displayed by the manager is set to 6, the synopsis display time is shorter than 1 minute and 20 seconds . On the contrary, when the number of objects to be simultaneously displayed is set to four, the display time is adjusted to be longer than 1 minute and 20 seconds as shown in Fig.

Although not illustrated in FIGS. 4 and 5, it is also possible to set a position at which an object to be displayed on a synopsis image is directly arranged by a manager through a UI (User Interface) such as a scroll bar. At this time, the administrator can arrange the objects in the order of the longest occurrence time, and arrange the remaining objects so that they do not appear at the same point at the same time.

Although not shown in FIG. 5, the synopsis image generated by the integrated control unit 120 is transmitted to the police terminal 130, the first communication device 150, and the second communication device 160 as needed. Alternatively, the administrator may store the result of the analysis through the synopsis image in the integrated control unit 120 and transmit the result to the police terminal 130, the first communication device 150, and the second communication device 160, if necessary It is also possible.

3, when the administrator analyzes the generated synopsis image, it is determined that the object C1 matches the characteristic of the stolen vehicle, and information related to the object C1 is stored in the integrated control unit 120, (130), or may be transmitted upon request. That is, it is possible to easily extract the information about the stolen vehicle trajectory by transmitting the place and time of shooting the object C1 to the police station terminal 130.

When a property setting command for displaying a synopsis image is inputted to the integrated controller 120 according to the characteristics of the objects, the objects are generated to be displayed on the synopsis image by color, size, moving direction, and speed according to the property setting command do. 3, a synopsis image may be generated by setting the size of an object so that only a person is displayed on the synopsis image.

When the reproduction speed changing command for changing the reproduction speed of the synopsis image generated in the integrated controller 120 is received, the synopsis image is displayed on the screen according to the changed reproduction speed. That is, it is possible to analyze the surveillance image by setting the synopsis image to be reproduced at a rate that the administrator can analyze.

Through the above process, the surveillance image can be quickly and accurately searched for and provided to a necessary place.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
