Description

TECHNICAL FIELD [0001] The present invention relates to an intelligent crime prevention system and a method for performing the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an intelligent crime prevention system and a method of performing the same. More particularly, the present invention relates to an intelligent crime prevention system and a method of performing the same.

The installation of CCTV (Closed-Circuit Television) is increasing to prevent and solve accidents. If you look briefly at a crime prevention system using conventional CCTV, you will install a number of CCTVs in various places, and the operator monitors the monitor connected to the CCTV at the integrated control center.

If more than 6000 to 10000 CCTVs are installed, all images must be monitored at the same time. In this case, problems related to the installation of monitors for each CCTV as well as insufficient management manpower and the number of cameras allocated per manpower are 600 to 1000 Continuous and urgent monitoring is not possible if 24 - hour monitoring is required.

However, since a camera angle is set at an arbitrary angle, a square is generated at an angle, and therefore, the angle of the camera is changed. There is a problem that it is not possible to monitor important matters such as criminals, crime scenes, and vehicles.

In addition, in order to reduce the square of the sequential monitoring method by designating the preset area, an object tracking type in which a rotary camera is installed at one point of an intersection and a detection camera for fixedly monitoring a specific direction are provided. This object tracking type has excellent characteristics in detection of people and vehicles by tracking objects one by one, but it is required to operate the camera for 24 hours to cause erroneous detection, causing confusion of the operator, frequent failure of the camera There is a problem that the effectiveness is deteriorated.

As described above, in the conventional CCTV-based crime prevention system, although the number of CCTV installations is continuously increased, there is a problem that it is difficult to expect the effect of crime prevention because of the lack of the management personnel capable of monitoring the CCTV. Also, even if a crime occurs in the area where CCTV is installed, there is a possibility that the event image is not available due to the blind spot of the camera, and it is difficult to grasp the accurate object even if the event image is captured.

1 is a block diagram of an intelligent crime prevention system according to a preferred embodiment of the present invention.

1, the intelligent security system according to the preferred embodiment of the present invention includes a camera module 100 and a central control center server 200 connected to the camera module 100 so as to transmit and receive information, .

The camera module 100 includes at least one camera. The camera module 100 is installed at an actual position to perform crime prevention and may be installed in a structure already installed at the corresponding position or in a dedicated structure for installing the camera module 100 have. The camera module 100 will be described later in more detail with reference to FIG.

The central control center server 200 is connected to the camera module 100, receives an image photographed by the camera, and can transmit a control signal for controlling the camera. The central control center server 200 includes a camera control unit 210, an image analysis unit 220, a storage unit 230, and a central control unit 240.

The camera control unit 210 performs an interface with the camera module 100 and is connected to the camera module 100 to control the corresponding camera among a plurality of cameras in the camera module 100 according to a control signal of the central control unit 240 So as to perform an operation according to the signal. In some cases, a camera control signal may be generated by the camera controller 210 alone.

More specifically, when an object appears in the detection area of the camera module 100, the camera control unit 210 controls the camera corresponding to the detection area in which the object appears so that the image of the appearance point where the object appears is captured .

After the camera captures an image of the object at the point of appearance, the camera control unit 210 causes the image of the point moved by the predetermined shooting interval to be taken again from the object's appearance point. Further, after capturing an image of a point shifted by a preset shooting interval from the appearance point of the object, the image of the shifted point is photographed after moving again by a predetermined shooting interval from the image shooting point. This process is repeated for a predetermined number of object shooting times.

The camera control unit 210 controls the camera for capturing an image to capture an image on a plane basis. Here, the unit of surface may be a square shape having a size of n x m, which will be described in more detail later in Figs. 5A and 5B.

In the present embodiment, the number of object photographing times is the total number of photographing times at which the camera performs photographing at the appearance of one object, and can be set by the manager in accordance with the size of the detection area of the camera. Here, the appearance of a single object does not mean one object, but the camera module 100 senses the appearance of a single object even if a large number of objects appear at the same time regardless of the number of objects.

 When the detection area to be detected by the camera is large, the number of object photographing can be set to a large number. When the detection area is small, the object photographing number can be set to be small. For example, the number of object shooting times can be set to 3, 5, 7, and if the number of object shooting times is 3, the shooting interval is shifted including the image of the emergence point where the first object appeared, More shooting can be done.

The image analysis unit 220 analyzes the image provided from the camera module 100. More specifically, the image analysis unit 220 can process the reference image by combining the images photographed by a later-described rotary camera, and extract road image information and surrounding image information from the reference image. Here, the image analyzing unit 220 can recognize the road by analyzing all the road image information such as the screen edge, the lane color, the lane pattern, and the surrounding image information of the reference image. For example, the image analysis unit 220 can recognize a road environment such as a lane, a direction, a shoulder road, and surrounding environment such as a sidewalk, a building, and a tree through image processing.

The storage unit 230 stores all information necessary for the operation of the security system. For example, when the camera module 100 is installed in the storage unit 230, the first captured image is stored. Thus, when the present security system is used for illegal parking, ) To compare the images inputted from the vehicle.

The central control unit 240 controls overall operation of the central control center and controls signal input / output between the camera control unit 210, the image analysis unit 220, and the storage unit 230.

The central control unit 240 controls the operation of the camera module 100 through the camera control unit 210 and when the captured image is input from the camera module 100, the image analysis unit 220 analyzes the captured image . The central control unit 240 stores information generated by the operation of the camera control unit 210 and the image analysis unit 220 in the storage unit 230 as necessary.

The central control unit 240 can set the direction of the intersection in which the camera is installed by using the road image information and the surrounding image information extracted by the image analysis unit 220 in order to set the reference image in the initial operation of the present security system The distance value may be calculated by a camera calibration technique, and the calculated distance value may be provided to the camera control unit 210. Here, the technique of calculating the distance value using the camera calibration technique is already known, and a description thereof will be omitted.

In this way, the security cameras for monitoring the road conditions can be installed in a structure installed in the road, for example, a milestone table, a pole, etc., or a dedicated structure can be installed separately if a conventional structure is difficult to use.

The rotary type camera 110 performs 360 degrees of photographing in an oblique direction with respect to the installation position, and is advantageous in that it can be photographed at various angles even if only one is installed. However, in the case of the rotary type camera 110, since the detection distance is short, it is difficult to grasp all the road conditions.

Therefore, a plurality of detection cameras 120 are installed together with the rotary type camera 110. Fig. In this embodiment, three detection cameras 120 are installed at different angles. However, the present invention is not limited thereto. In the case of an intersection, it is preferable that four detection cameras 120 are provided for each lane for monitoring each lane.

In this way, one rotating camera 110 and a plurality of detection cameras 120 are installed adjacent to each other, and they are controlled by the central control center server 200 through the interface with the camera control unit 210.

As a result, as shown in FIG. 3A, the camera module 100 captures a 180-degree image in a vertical direction at an installation point and recognizes the direction. It is preferable that the camera state value at the time of photographing a 180 degree image by the camera module 100 is stored in the storage unit 230. [ The camera state value at this time may be a reference at the time of 360-degree photographing in the rotary type camera 110, which will be the next operation.

Then, the central control unit 240 controls the camera module 100 to take 360-degree photographs in a horizontal direction about the installation point. Thus, the rotary camera 110 takes a 360-degree photograph around the installation point, and the area photographed by the rotary camera 110 is circled in FIG. 3B. An image photographed by the rotary camera 110 is input to the central control center server 200, an image is processed by the image analysis unit 220, and a camera state value is stored in the storage unit 230 .

It is assumed that the four detection cameras 120a, 120b, 120c, and 120d are assumed to have the same specifications, and each detection area is set to 150 meters. When an object appears in at least one of the detection areas B, C, D, and E, that is, when motion is captured, the detection cameras 120a, 120b, 120c, and 120d corresponding to the detection area Any one of them) operates.

In this embodiment, an object has occurred at a position 150 m in the detection area C. Thus, the detection camera 120b captures an image for a preset shooting time for an nxm shooting area according to a predetermined bar including a 150m point. Thereafter, the object moves to the 110m point, and the detection camera 120b moves the shooting point and again captures the image during the shooting time, and the object is also included in the image.

The object appearing at the point 50m in the detection area D is photographed by the operation of the detection camera 120c and the object emerging at the point 30m in the detection area E is photographed by the operation of the detection camera 120d. The detection camera 120c and the detection camera 120d also move to the photographing point to perform photographing again, so that the respective objects are included in the plurality of images.

5A and 5B are views for explaining setting of an imaging area for recognizing and capturing an object in an intelligent security system by image capturing according to a preferred embodiment of the present invention.

Referring to FIG. 5A, the central control unit 240 sets a plurality of photographing areas in advance of n × m in size, so that the camera module 100 detects one of the plurality of photographing areas, For example, 5 seconds to 10 seconds for only a selected shooting region by selecting a shooting region. The photographing area set by the central control unit 240 is illustrated as a rectangle in the drawing.

In Fig. 5B, a photographing area in the detection area for the detection cameras 120a, 120b, 120c, and 120d will be described. In the present embodiment, the detection cameras 120a, 120b, 120c, and 120d may be installed at an intersection and fixed toward one lane, or may be installed in an alleyway.

In this embodiment, the detection cameras 120a, 120b, 120c, and 120d can detect up to a point 100m away from the installation position. When an object appears within 100m, motion of the object occurs to detect the object, And the object is photographed in accordance with the control signal of the camera control unit 210.

Before the security camera 120a, 120b, 120c, or 120d performs a security operation, the central control unit 240 sets an image area of n.times.m size as illustrated in FIG. 5A.

Accordingly, when it is detected that an object appears in the detection area of the detection cameras 120a, 120b, 120c, and 120d, the detection camera F proceeds to take an image of the shooting area F to which the appearance point of the object appears. At this time, the photographing is continued for a predetermined photographing time. At this time, the photographing area F to which the emergence point of the object appears belongs to a position 100 meters away from the installation position of the detection cameras 120a, 120b, 120c, and 120d.

After one of the detection cameras 120a, 120b, 120c, and 120d shoots the shooting area F where the appearance point of the object appears during the preset shooting time, the detection camera moves by a predetermined shooting interval, Move 20m and proceed to the second shot at 80m. In this case, the photographing is continued for a predetermined photographing time, for example, 5 to 10 seconds, and the photographing is progressed for the photographing area G corresponding to the 80-m point.

After one of the detection cameras 120a, 120b, 120c, and 120d performs the shooting for 5 seconds to 10 seconds with respect to the second photographing area G, ) For 5 seconds to 10 seconds.

As described above, in the present embodiment, it is assumed that the image capturing is performed on the assumption that the capturing interval is set to 20 m for the detection cameras 120a, 120b, 120c, and 120d, and the number of object capturing times is set to three Respectively. Each of the shooting regions F, G, and H is selected according to the position of the object in the shooting regions illustrated in FIG. 5A.

6 is a flowchart illustrating a procedure for automatically setting a camera according to a preferred embodiment of the present invention.

Hereinafter, with reference to FIG. 1 to FIG. 6, a description will be given of a procedure for automatically setting a camera to be performed in advance in order to implement an intelligent crime prevention system by image capturing.

Install the camera module on the street structure at the location where security is required. The camera module 100 includes a plurality of detection cameras 120, and the plurality of detection cameras 120 are installed at different angles according to areas to be sensed (S301).

Under the control of the camera control unit 210, the plurality of detection cameras 120 capture a 180-degree image at a right angle around the installation point (S303). The photographed 180-degree image can be used to recognize the direction at the central control center server 200.

After a plurality of detection cameras 120 have captured a 180-degree image, the camera control unit 210 controls the rotation-type camera 110 to photograph a 360-degree image in a horizontal direction around the installation point S305).

Thereafter, the 180-degree image and the 360-degree image are input to the central control center server 200, and the image analyzing unit 220 processes the reference image by combining the input images (S307).

After the reference image processing, the image analysis unit 220 extracts the road image information and the surrounding image information (S309). Accordingly, the central control unit 240 recognizes the road, the sidewalk, the building, the tree, the lane, the direction, the shoulder, and the like using the road image information and the surrounding image information extracted by the image analysis unit 220, .

The central control unit 240 calculates a distance value by camera calibration using a known technique using road image information and surrounding image information (S313), and sets the pan / tilt / zoom value of the camera using the calculated distance value And controls the camera module 100 (S315).

After completing the setting of the camera module 100, it is not necessary to perform the procedure of FIG. 6 again unless a special reason is generated. By the control of the central controller 240, the camera module 100 ), Thereby performing the operation of the present security system.

7 is a flowchart illustrating an intelligent crime prevention method according to the preferred embodiment of the present invention.

Hereinafter, a method of performing image capturing by a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. The camera module 100 assumes that the camera automatic setting is completed by the procedure of FIG.

The camera module 100 continuously monitors the detection area according to the setting at the installation point (S401). If there is no change in the sensing area, no action is required. However, if it is detected that an object has appeared in any one of the camera modules 100 (S403-Y) (120a, 120b, 120c, and 120d) that detects a detection region in which an object appears, thereby capturing an image of an object appearance point (S405).

After one of the detection cameras 120a, 120b, 120c and 120d shoots for a pre-set shooting time for an object occurrence point, that is, for the first shooting area, it moves by the shooting interval from the first shooting area, Shooting is performed during the shooting time (S407).

The central control unit 240 determines whether or not the sensing cameras 120a, 120b, 120c, and 120d have photographed the number of times of object shooting and the number of images input from the sensing cameras 120a, 120b, 120c, and 120d is If the number of object photographing times is satisfied (S409-Y), the image photographed by the detection cameras 120a, 120b, 120c and 120d is stored in the storage unit 230 (S411).

If the image photographed by one of the detection cameras 120a, 120b, 120c and 120d is smaller than the number of object photographing operations (S409-N), the central control unit 240 controls the detection cameras 120a, 120b, 120c, 120d) moves from the second photographing area by the photographing interval and controls the third photographing area to take an image. This process is repeated until the image photographed by the detection cameras 120a, 120b, 120c, and 120d meets the object photographing count. Finally, when the photographing by the detection cameras 120a, 120b, 120c and 120d is completed, the images photographed by the detection cameras 120a, 120b, 120c and 120d are stored in the storage unit 230 (S411).

According to the present embodiment, when the object appears in each detection area, the plurality of detection cameras 120 proceeds to shoot for a preset shooting time with respect to the shooting area in units of the surface with respect to the point where the object appears, The photographing operation is continued for a predetermined photographing time with respect to the photographing area of the unit of surface movement.

Therefore, there is an advantage that the overhead of the camera can be reduced, and the object can be tracked without missing, compared with the conventional method in which the object is tracked every time the object is generated.

The number of object photographing times for the camera module 100 can be set to a large value in an area where object tracking is required to be more aggressive. In this case, the object can be tracked more finely by the same system.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
