Description

Method and device for monitoring object by setting surveillance area {METHOD AND APPARATUS FOR PROCESSING AN OBJECT SURVEILANCE BY SETTING A SURVEILLANCE AREA}

The present invention relates to an object monitoring method and apparatus for detecting and monitoring a moving object.

Recently, various image processing apparatuses are being developed by the development of image processing technology. In particular, such an image processing apparatus includes a function of detecting a moving object in an image, and specifically, an object monitoring function of detecting and tracking a moving object in a screen being monitored through the image processing apparatus. Technical development is taking place. For example, as a product widely known as the object surveillance device, CCTV (Closed-Circuit Television) is a typical product, and the object monitoring device is applied in various fields such as crime prevention or privacy protection. This is possible.

In relation to this, there are two types of cameras constituting the object monitoring apparatus, a stationary type and a tracking type. The fixed type refers to a camera in which a view of the camera is fixed, and which can monitor a moving object only within the view. On the contrary, the moving type means a camera that can move mechanically and can track movement along a moving object.

In this regard, as the mobile type camera, for example, a PTZ (pan, tilt, zoom) type camera has been developed. The footage camera can automatically track the moving object along the path of movement of the object while panning, tilting and zooming the moving object.

In recent years, a method of detecting an object moving only within the surveillance region by setting a surveillance region for monitoring the object has been developed. In this regard, the surveillance zone is also referred to as an 'event zone' or a 'privacy zone', hereinafter referred to as a 'surveillance zone'. The reason for setting the surveillance area is that only the objects moving in the specific surveillance area can be efficiently monitored since the object monitoring is not performed for portions other than the intra-screen surveillance area. In addition, some countries may not legally monitor the interior of a house or building to protect the privacy of individuals, in which case a mandatory monitoring area may be established.

1 (a) and 1 (b) show an example of setting a surveillance area using a fixed camera, for example. In particular, in the case of FIG. 1A, when only the vehicle passing through the road part in the screen 10 is to be monitored, only the corresponding road part is set as the monitoring area 10a. In addition, FIG. 1 (b) shows an example in which only a portion of a road through which a vehicle passes is set as the monitoring area 11a on the screen 11 in which a residential street and a house coexist, except for an area in which private privacy such as the inside of a house should be protected. It is shown.

1 (a) and (b) show a case where the user simply sets the desired area as the surveillance area in the case of the fixed camera, or the surveillance area in the case of the mobile camera described above. The same problem exists.

2 (a) and 2 (b) are diagrams for explaining a problem of setting a surveillance area in monitoring an object using a conventional mobile camera. That is, when only the road portion in the screen 12 is to be set as the monitoring area 12a as shown in FIG. 2 (a), as the position of the camera is moved by the pan / tilt / zoom method, the screen is moved. This will be changed from time to time. Therefore, when the surveillance region 12a is set as shown in FIG. 2A and the camera is moved as illustrated in FIG. 2B, the surveillance region 12a set in the screen 13 is not changed. A problem arises in that an unwanted area is monitored instead of the area 13a which was actually wanted to be monitored. Therefore, in the case of the conventional mobile camera, in general, object monitoring is usually performed without setting a surveillance area. However, even in the case of applying a mobile camera, the setting of the surveillance area will be required by law or for efficiency of use.

The present invention relates to a method and apparatus for efficiently detecting and monitoring a moving object in a screen. In particular, the present invention is to provide a method and apparatus for monitoring an object by setting a surveillance area in a mobile camera.

For reference, the embodiments provided by the present invention are provided as an example for describing the technical idea of the present invention, and the technical scope of the present invention is not limited to the provided embodiments.

3 illustrates an entire system of a video surveillance apparatus according to an embodiment of the present invention. The system of the present invention is largely composed of an image capturing apparatus 1, an object monitoring apparatus 2, and a communication network 3. However, this is presented as an example for description of the present invention, it is obvious that the image acquisition device 1 may be configured together in the object monitoring device (2). In this regard, the object monitoring apparatus 2 is applicable to various products irrespective of the term, for example, a personal PC, a TV, a mobile phone, etc., which are widely used at present, may correspond to the object monitoring apparatus. It can also be called 'user terminal'.

For example, the image capturing apparatus 1 may correspond to a camera capturing an image (hereinafter, referred to as a “camera” means an image capturing apparatus), for example, a mobile type as described above. This is the PTZ camera. In addition, although only one camera is illustrated as an example in FIG. 3, it will be apparent that a plurality of cameras may be used by being connected to the object monitoring apparatus 2 through the communication network 3.

As described above, the communication network 3 is a network network in which the camera 1 and the object monitoring device 2 are exchanged with each other. it means. The communication network 3 may be wired or wireless. For example, the communication network 3 may be a wired communication network or a wireless communication network connected to the Internet. However, in the use case where the camera 1 is integrated in the object monitoring apparatus 2, the communication network 3 may be excluded from one component of the system of the present invention.

The object monitoring apparatus 2 may include a communication means 21, an object monitoring unit 22, a monitoring area setting unit 23, a display unit 24, an interface unit 26, and a controller 25. Can be.

In particular, the object monitoring unit 22, the monitoring area setting unit 23, and the control unit 25 among the above components may be implemented as a software program instead of hardware. Therefore, it may be provided as a recording medium (ROM) for storing a program consisting of the software.

Hereinafter, each component of the object monitoring apparatus 2 will be described in detail. The communication means 21 means a wired or wireless communication means interlocked with the communication network 3. Accordingly, the communication means 21 receives the image acquired by the camera 1 and transmits the image to the object monitoring unit 22. The display unit 24 is configured as a display screen that provides a visual screen to the user, and may be, for example, various means of display such as an LCD and an LED. In particular, the display unit 24 performs a function of displaying an object detected by the object monitoring unit 22 and a monitored result on an image screen obtained by the camera 1. In addition, the display unit 24 displays a user selection screen provided by the surveillance region setting unit 23 to be described later.

In addition, the interface unit 26 is provided for interaction with the user, for example, a keyboard module, a remote control module, a mouse module, and the like. The user command is received through the interface unit 26, and the execution of the received command is shown on the display screen.

In addition, the control unit 25 controls all components in the object monitoring apparatus 2, in particular, controls to set the object monitoring area by the monitoring area setting unit 23, and also in the object monitoring unit 22 The controller detects and monitors an object based on the set surveillance region.

In addition, the object monitoring unit 22 may include an object detection engine, an object type classification engine, and an object tracking engine. The object detecting engine includes a function of detecting a moving object from image information received from the camera 1. In addition, the object type classification engine includes a function of distinguishing and classifying the types of objects on the screen, and particularly, having a function of identifying the object of the type when a specific object type desired to be monitored by the user is designated. do. In addition, the object tracking engine includes a function of tracking an object determined to be monitored. Each function of the object detector 22 may be configured by a software program.

In this connection, although not shown in the drawings, the object monitoring unit 22 may be provided in the camera 1. That is, in the use example in which the camera 1 and the object monitoring device 2 are separated, the object monitoring device 2 communicates camera control information including information on the monitoring area set by the monitoring area setting unit 23. The camera 1 transmits the result through the means 21 and the communication network 3, and the camera 1 receives the result of the object monitoring through the internal object monitoring unit 22 through the communication network 3 again. To 2).

The surveillance area setting unit 23 provides a graphical user interface (GUI) to enable a user to set an area for monitoring an object. In addition, the surveillance region setting unit 23 performs a function of finally checking and setting a surveillance region suitable for the position of the mobile camera. Hereinafter, various embodiments of the surveillance region setting by the surveillance region setting unit 23 will be described.

4 to 6 are diagrams for explaining an object monitoring method by setting a surveillance area according to an embodiment of the present invention. In this regard, the present embodiment is characterized by first setting the entire surveillance region from the entire background screen within the camera movement range for the final surveillance region setting.

4 is a flowchart illustrating a method for monitoring an object by setting a surveillance area according to a temporary embodiment of the present invention.

First, the surveillance region setting unit 23 pans / tilts the camera 1 to obtain a whole background screen that can be monitored within the movable range and provides the same to the user through the display unit 24. (S100). 5 illustrates an example of the entire background screen 100 acquired through step S100. In order to acquire the entire background screen 100, the control unit 25 or the surveillance area setting unit 23 controls a pan angle and a tilt angle of the camera 1 to control a specific pan / tilt value. Acquire an individual picture from. Hereinafter, in the present invention, the term "pan / tilt value" is used to mean a "pan / tilt angle value" for identifying a camera position.

For example, the horizontal screen of the entire background screen 100 has a pan angle (pan_angle = x1, x2, x3, x4, x5, x6) at a specific tilt angle (any one of tilt_angle = a1, a2, a3, a4). It consists of the screens obtained by changing the (for example, 101, 102, 103, 104, 105, 106). Also, for example, the vertical screen of the entire background screen 100 may have a tilt angle (tilt_angle = a1, a2, a3, a4) at a specific pan angle (any one of pan_angle = x1, x2, x3, x4, x5, x6). ) Are configured by screens (eg, 101, 111, 121, 131) obtained by changing. The individual screens 101 to 106 and 111 to 113, which are obtained by repeatedly performing the above process by changing the pan / tilt angles, are arranged according to their respective positions, and the overlapping images are removed and the entire background screen is removed. It becomes possible to acquire 100. Although FIG. 5 illustrates a full screen without a duplicate image, there is a duplicate image when the actual acquisition screen is viewed as the full screen of the display device. Therefore, it is possible to configure and display the full screen without removing the duplicate screen. In FIG. 5, all of the setting lines of the main surveillance area 100a to be described later are smoothly connected. However, in the entire screen in which the duplicate image is not removed, the setting lines are not connected to each acquisition screen.

In relation to this, in the present embodiment, for convenience of explanation, the horizontal screen is obtained by changing the pan angle and the vertical screen is obtained by obtaining the entire background screen by changing the tilt angle, but the vertical screen is changed by changing the pan angle. It is also possible to obtain a horizontal screen by changing the tilt angle. In addition, in the case of a specific mobile camera, both the vertical and horizontal screens may be obtained only by changing the pan angle, and the tilt angle may be defined as a fine moving screen given at a specific pan angle. Therefore, the entire background screen of the present invention can be obtained through various manipulations of the pan / tilt angle of the camera 1.

In addition, the pan / tilt value for composing the entire background screen is determined as a specific angle value that forms the most natural entire background screen. That is, for example, between the pan angles (x1, x2, x3, x4, x5, x6) or the tilt angles (a1, a2, a3, a4) constituting the entire wallpaper, Although not a pan / tilt value, it means that there may be another pan angle and / or tilt angle at which the camera can be positioned. A specific example thereof will be described later with reference to FIG.

When the entire background screen 100 is obtained, the surveillance area desired by the user is set in the entire background screen 100 (S110). In particular, in the present invention, in order to distinguish the surveillance area set in the entire background screen from the surveillance area for each camera position to be described later, the main surveillance area is named. FIG. 5 illustrates an example in which a part of a road to be monitored is set as the main monitoring area 100a in the entire background screen 100.

6 illustrates an example of a graphical user interface (GUI) screen for setting a main surveillance area. Providing the entire background screen 100 through the display unit 24, if the user wants to set the surveillance region, click the region 300, and then the corner portion of the region to be set as the surveillance region in the entire wallpaper 100 Is designated as the point (501 to 506). When the point designation is completed, the inside of the figure connecting the point by a line is set as the main monitoring area 100a. When setting of the final main monitoring area 100a is completed, the object monitoring according to the main monitoring area is performed by clicking the execute button 400, and the main monitoring area 100a is changed or canceled to cancel the execution. The button 410 may be further provided separately. That is, the user can easily set the main surveillance area 100a and perform object monitoring through his terminal screen.

In FIG. 5 and FIG. 6, the main monitoring area 100a configured in the form of a closed polygon is set, but it may be set in various forms such as a straight line, a curved line, a closed circle, and a closed ellipse.

When the setting of the main surveillance region 110a is completed through the step S110, in order to perform object monitoring in the main surveillance region in earnest, first, it is necessary to confirm the current position of the camera 1 (S120). ). The current position of the camera 1 can be obtained by the pan / tilt angle value of the current camera. Alternatively, the pan / tilt angle information of the camera on each obtained screen may be stored in advance at the time of constructing the full screen.

When the position of the current camera is determined by the step S120, the surveillance area in the current camera position screen is automatically set (S130). For convenience of description, the surveillance area that is automatically set at the current camera position is called a 'sub surveillance area'. When the sub surveillance area is automatically set, an object moving in the sub surveillance area is monitored at the current camera position (S140).

In relation to this, the automatic setting of the sub monitor area according to the step S130 will be described with reference to FIG. 5. For convenience of description, FIG. 5 illustrates three cases (a), (b), and (c) for the current camera position.

FIG. 5A illustrates a case in which a part of the main monitoring area 100a exists in the corresponding location screen while the pan / tilt angle is the same as the pan / tilt angle used to acquire the entire background screen. That is, the case where the current camera position is confirmed as 'pan_angle = x3 and tilt_angle = a1' by the above-described step S120 is taken as an example. When the current position of the camera is confirmed, the pan / tilt value constituting the entire wallpaper and the pan / tilt value of the current camera position are compared with each other. In the case of FIG. 5A, as described above, the pan / tilt angle used to acquire the entire background screen is the same as 'pan_angle = x3 and tilt_angle = a1'. Therefore, in this case, the screen 103 generated at the corresponding camera position is the same as some screen 103 of the screens constituting the entire background screen. It is determined whether some of the setting lines connecting the main surveillance area 100a set on the entire screen are located on the screen 103. That is, the setting line is positioned at the lower right and upper right portions of the screen 103, and the monitoring region setting unit 23 determines the end position of the setting line connecting the lower right and upper right portions, and the right screen region of the setting line. Is set to the surveillance region 103a.

Therefore, it is possible to easily determine whether a part of the main monitoring area 100a exists in the screen 103, and finally, a part of the main monitoring area existing in the current camera position is automatically set as the sub monitoring area 103a.

5 (b) is the same pan / tilt angle used to obtain the entire wallpaper, but with a pan / tilt angle. A case in which a part of the main monitoring area 100a does not exist in the location screen is shown. That is, the case where the current camera position is confirmed as 'pan_angle = x5 and tilt_angle = a1' by the above-described step S120 is taken as an example. When the current position of the camera is confirmed, the pan / tilt value constituting the entire wallpaper and the pan / tilt value of the current camera position are compared with each other. In the case of FIG. 5B, the pan / tilt angle used to acquire the entire background screen is the same as 'pan_angle = x5 and tilt_angle = a1' as described above. Therefore, in this case, the screen 105 generated at the corresponding camera position is the same as some of the screens 105 of the entire screen. Therefore, it is possible to easily determine whether a part of the main surveillance area 100a exists in the screen 105, and if it is determined that no part of the main surveillance area exists in the current camera position, without setting the sub surveillance area. The camera operates as if the surveillance area does not exist at the position of the camera. In relation to the operation in which the surveillance region does not exist, for example, it is possible to monitor all moving objects or terminate the surveillance of an object in any region of the current camera position, which may be determined by a system or a user's setting. .

FIG. 5C illustrates a case in which the pan / tilt angle value of the current camera position is different from the pan / tilt angle value used to obtain the entire wallpaper. That is, the case where the current camera position is confirmed as 'pan_angle = y1 (x3 <y1 <x4) and tilt_angle = b1 (a2 <b1 <a3)' by the above-described step S120 is taken as an example. When the current position of the camera is confirmed, the pan / tilt value constituting the entire wallpaper and the pan / tilt value of the current camera position are compared with each other. In the case of (c) of FIG. 5, the pan / tilt 'y1' and 'b1' values indicating the current camera position are 'pan_angle' as the pan angle among the pan / tilt angles used to obtain the entire background screen. It can be seen that the case exists between 'x3 ~ x4' and 'tilt_angle = a2 ~ a3' as the tilt angle (110, dotted line in FIG. 5). That is, the pan / tilt value (eg, y1, b1) indicating the current camera position is compared with the pan / tilt value (eg, x3, x4, a2, a3) constituting the entire background screen. It is possible to confirm exactly which ratio differs, from which it is possible to infer the screen 110 at the current camera position y1, b1. On the other hand, it is possible to set the size of the region 110 by comparing the positional information of the upper left and right corners of the region 110 with the positions on the acquisition screens (x3, a2) and (x4, a3). Do. Alternatively, the pan angle may be set based on a distance difference between the vertical line of the area 110 and the adjacent vertical line of the acquisition screen (x3, a2) or (x4, a3), and the horizontal line of the area 110 and the acquisition screen (x3). It is possible to set the tilt angle by the difference in distance from adjacent horizontal lines of a, a2) or (x4, a3).

When the screen 110 at the current camera position is determined, it becomes possible to confirm that a portion of the main surveillance region 100a exists in the current camera position, and sub-monitors a portion of the confirmed main surveillance region 100a. Automatically set to the area 110a.

That is, according to the above example, in the case of (a) and (c) of FIG. 5, the object monitoring is performed in the sub-monitoring areas 103a and 110a which are automatically set by using the main monitoring area 100a. It is lost (S140). If the current camera position is changed by the movement of the camera (S150), the process returns to step S120 to confirm the current camera position (S120), and after setting the sub-surveillance area at the current camera position (S130). In step S140, the object monitoring is repeated.

In addition, information on the sub-monitoring areas of the respective acquisition screens (eg, 101 to 106 and 111 to 113) is stored in the camera 1 or the monitoring device 2 together with pan / tilt angle information of the corresponding screen. It is done.

Thereafter, in the case of an acquisition screen in which the sub-surveillance area does not exist, for example, the screen 105, the user may set the camera to cancel the movement information and the image acquisition.

Therefore, the user can simplify the setting of the operation of setting the surveillance area and obtaining the required image while displaying the full screen.

7 to 8 illustrate an object monitoring method by setting a surveillance area according to another exemplary embodiment of the present invention. In this regard, the present embodiment is characterized by presetting a unique surveillance area for each camera position.

7 is a flowchart illustrating an object monitoring method by setting a surveillance area according to another embodiment of the present invention.

First, the surveillance region setting unit 23 sets a unique surveillance region for each specific position of the camera 1. For convenience of description, a specific position of the camera is called 'preset'. That is, FIGS. 8A and 8B are diagrams for explaining a surveillance area set for each preset of a camera. For example, (a) of FIG. 8 is a case where the preset position of the camera is given as 'pan = x1 and tilt = y1', and the road portion in the screen 200 is set as the monitoring area 201 at the preset position. The case is shown. 8B illustrates a case where the preset position of the camera is given as 'pan = x2 and tilt = y2', and the case where the road portion in the screen 210 is set as the monitoring area 211 at the preset position is shown in FIG. It is shown. In relation to this, the method for setting the monitoring areas 201 and 211 for each preset position may be set in the same manner as described with reference to FIG. 6. That is, for example, after providing a screen in the preset to the display unit 24 through a graphical user interface (GUI), the user designates the area to be monitored within the screen as a point and connects the point. It is possible to set the inside as a monitoring area.

In operation S200, when a unique surveillance region is set for each camera preset position, the current position of the camera is checked (S210), and whether the surveillance region set at the current camera position exists (S220). The step S220 is performed by checking whether the current camera position is the same as the preset position where the surveillance region is set.

If it is determined in step S220 that the surveillance region exists (S230), the object moving in the surveillance region is monitored based on the surveillance region set at the current camera position (S240). If the current camera position is changed after the movement of the camera (S250), the process returns to step S210, and the process of checking whether there is a surveillance area at the new camera position is again performed.

If it is determined in step S220 that there is no surveillance area (S230), it is determined that there is no surveillance area setting at the current camera position, and the moving object is monitored on the entire screen (S260). In relation to this, the step S260 may be set by the user or the system design to terminate the object monitoring tracking function at the camera position where there is no surveillance area setting. In addition, after the step S260, if the current camera position is changed by the movement of the camera (S270), the process returns to the step S210, and the process of checking whether there is a surveillance area at the new camera position is again performed.

Although the technical spirit of the present invention has been described in detail according to the above embodiment, it should be noted that the above embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
