Hereinafter, with reference to FIGS. 2 to 6, the intelligent video transmitting apparatus 200 and the method for checking an event in the intelligent video transmitting apparatus 200 and reporting the event to the management center 100 will be described in detail. .

2 is a diagram showing the configuration of an intelligent video transmitting apparatus according to an embodiment of the present invention.

As shown in FIG. 2, the intelligent image transmitting apparatus 200 according to the preferred embodiment of the present invention includes an image collecting unit 210, a communication unit 220, a filtering unit 230, a message generating unit 240, and storage. The unit 250 and the image analyzer 260 are included.

The image collector 210 is connected to one or more cameras to perform a function of collecting the image screen photographed by the camera. The image collecting unit 210 may be connected to the camera by a cable to perform a wired communication with the camera, and may also perform short-range wireless communication with the camera through a wireless protocol such as Bluetooth or Zigbee.

The communication unit 220 performs a function of communicating with the management center 100 through the wired or wireless network 300. That is, the communication unit 220 transmits the image data collected by the intelligent image transmission device 200 to the management center 100, and also transmits the event information to the management center 100. In addition, the communicator 220 transmits the event related message generated by the message generator 240 to the manager's mobile communication terminal through the wired / wireless network 300.

The storage unit 250 includes the reference video screen information, the YUV component value of the reference video screen, the range information of the event area, the range information of the prohibited area, the range information of the valuable goods storage area, the video screen information of the valuable goods, and the mobile communication phone number of the manager. Save it. The storage unit 250 may store range information of pixel coordinate values as range information of an event area or a prohibited area. In addition, the storage unit 250 is a YUV component value of the reference video screen information, and includes Y component values (luminance signal values), U component values (differences between luminance signals and red components), and V component values (luminance signals and blue components). Save each). Here, the reference video screen is a video screen of a designated space (eg, a parking lot, a computer room door, an office door, a specific area of a museum) photographed by a camera, and the reference video screen does not include a dynamic object. That is, the reference video screen is a surveillance screen in which a moving dynamic object such as a person, an animal, or a car does not appear.

The filtering unit 230 corrects the image quality of the image screen collected by the image collecting unit 210. In detail, the filtering unit 230 removes image noise existing in the image screen collected by the image collecting unit 210, checks the contrast of the image screen, and adjusts the contrast to a preset range. For example, the filtering unit 230 adjusts the shaking image, and adjusts the contrast of the image screen in which phenomena such as darkening of the headlights of the car and dimness due to sudden climate change are displayed. In addition, the filtering unit 230 encodes the corrected image screen into image data having a predetermined standard and transmits the real-time to the management center 100 through the communication unit 220.

When the message generator 240 receives a text message transmission request from the image analyzer 260, the message generator 240 extracts a manager's mobile phone number from the storage unit 250, and then composes a message for notifying the corresponding event. Send to the phone number.

The image analyzer 260 analyzes the image data corrected by the filtering unit 230 and determines whether a roaming event, a appearing event, a disappearing event, a forbidden area entry event, theft event, or a scene change event have occurred in the currently monitored area. Check it.

In detail, the image analyzer 260 checks the event region on the image screen corrected by the filtering unit 230 and generates a roaming event when detecting a dynamic object that exists for a predetermined time or more in the event region. 220 is transmitted to the management center (100). The event area is information about a specific area on the full screen captured by the camera, and the image analyzer 260 checks the event area on the full screen of the image based on the range information of the event area stored in the storage 250. Dynamic objects also refer to moving objects such as people, animals, cars, and the like. In addition, the image analyzer 260 recognizes which dynamic object belongs to a vehicle, a human, or an animal based on the area, height, and size of the dynamic object.

In addition, the image analyzer 260 detects a newly entered dynamic object in the event area, generates an event, and transmits the generated event to the management center 100 through the communication unit 220, and the object located in the event area is the event. If it is out of the area generates a disappear event and transmits to the management center (100).

In addition, the image analyzer 260 checks the forbidden area area on the image screen corrected by the filtering unit 230 and detects an object entering the forbidden area, and generates a forbidden area entry event to generate the communication unit 220. Through the transmission to the management center 100, and requests the message transmission to the message generator 240. The forbidden area is information on a specific area on the entire screen photographed by the camera, and the image analyzer 260 checks the event area on the full screen of the image based on the forbidden area range information of the storage 250.

In addition, the image analyzer 260 checks the valuables storage area range information and the valuables image information (for example, valuable YUV component values or RGB values) on the image screen corrected by the filtering unit 230, and based on the image screen, the image analysis unit 260 checks the valuables storage area range information. Check whether the valuables located is detected, and if the valuables are not detected to generate theft event and transmits to the management center 100 through the communication unit 220.

On the other hand, the image analyzer 260 checks the YUV component value of the entire image corrected by the filtering unit 230, and compares the matching ratio between the YUV component value and the YUV component value stored in the storage unit 250 to obtain a matching rate. If less than a threshold value (eg, 40%), a scene change event is generated and transmitted to the management center 100 through the communication unit 220, and the message generator 240 requests the message transmission. That is, when the ratio of the YUV component value of the current screen to the YUV component value of the reference video screen stored in the storage unit 250 is less than 40%, the image analyzer 260 may cover the camera lens or change the camera angle. A scene change event is generated.

3 is a flowchart illustrating a method of detecting an event in an intelligent video transmission device and reporting the event to a management center according to an embodiment of the present invention.

Referring to FIG. 3, the image collecting unit 210 of the intelligent image transmitting apparatus 200 collects an image screen photographed by a camera (S301). Then, the filtering unit 230 removes image noise from the image screen, checks whether the contrast of the image screen is within the preset contrast range and adjusts the contrast of the image screen if it does not match (S303). Subsequently, the filtering unit 230 provides the image screen to the image analyzing unit 260, encodes the corrected image screen into image data having a predetermined standard, and transmits the image screen to the management center 100 through the communication unit 220. do.

Then, the image analysis unit 260 analyzes the image screen provided from the filtering unit 230, the conditions of occurrence of the roaming event, appearing event, disappearance event, forbidden zone entry event, theft event or scene change event in the image screen It is checked whether or not this is true (S305, S307). Subsequently, when at least one event occurrence condition is established among the plurality of event establishment conditions, the image analyzer 260 reports the corresponding event to the management center 100 using the communication unit 220 (S309). Accordingly, the management center 100 displays the event information received from the intelligent video transmission device 200 on the screen and outputs the event occurrence signal to the speaker, thereby notifying the administrator of the event occurrence.

Meanwhile, if the generated event is any one of a forbidden zone entry event, a scene change event, and a theft event, the image analyzer 260 requests the message generator 240 to transmit a message. Then, the message generator 240 extracts the manager's mobile phone number from the storage 250 and transmits a message related to the event to the mobile phone number. For example, when the message generator 240 is requested to transmit a message according to the forbidden zone entry event, the message generator 240 transmits a text message such as "entrance to the forbidden zone is detected" to the manager's mobile communication terminal, and the scene change event. When a message is requested to send, a text message such as "Camera angle is changed or a foreign object is covering the camera lens" can be sent to the administrator's mobile communication terminal. Alternatively, when the message generator 240 is requested to transmit a message according to the theft event, the message generator 240 may transmit a text message such as "no valuables are detected" to the manager's mobile communication terminal.

Referring to FIG. 4, the image collecting unit 210 of the intelligent image transmitting apparatus 200 collects the image screen photographed by the camera (S401). Then, the filtering unit 230 removes image noise from the video screen, and adjusts the contrast of the video screen to match the preset contrast range (S403). Subsequently, the filtering unit 230 provides the filtered image screen to the image analyzing unit 260, encodes the image screen into image data having a predetermined standard, and transmits the image screen to the management center 100 through the communication unit 220. do.

Next, the image analyzer 260 checks the RGB value of the image screen provided from the filtering unit 230 and calculates the YUV component value based on the RGB value (S405). That is, the image analyzer 260 may determine the Y component value (luminance signal value) and U of the image screen based on the R value (red value), G value (green value), and B value (Blue value) of the image screen. The component value (difference between the luminance signal and the red component) and the V component value (difference between the luminance signal and the blue component) are calculated.

Subsequently, the image analyzer 260 compares the calculated YUV component values with the matching rates of the YUV component values stored in the storage 250 (that is, the YUV component values of the reference video screen), and the matching ratio is a threshold value (eg, , 40%) is checked (S407). Next, when the matching rate of the converted YUV component value and the YUV component value of the stored reference image screen of the storage unit 250 is less than a threshold value, the image analyzer 260 may cover the specific object or the camera. Recognizing that the angle has been changed, the scene change event is transmitted to the management center 100 through the communication unit 220 (S409). In this case, the image analyzer 260 stores the Y component value, the U component value, and the V component value of the image screen provided from the filtering unit 230, the Y component value, the U component value, and the V component value stored in the storage unit 250. Compared with each other, if any one of the coincidence rate of the Y component value, the coincidence rate of the V component value, and the coincidence rate of the V component value is found to be less than the threshold value, the scene change event is transmitted to the management center 100. Alternatively, the image analyzer 260 averages the match rates of the Y component values, the U component values, and the V component values, and transmits a scene change event to the management center 100 when the average match ratio is less than the threshold.

Preferably, the image analyzer 260 identifies a camera photographing the video screen among a plurality of cameras, and includes camera identification information in the scene change event. Then, in response to receiving the scene change event, the management center 100 outputs scene change event information to the monitor and outputs a scene change event occurrence sound to the speaker, thereby requesting the administrator for a quick action.

In addition, the image analyzer 260 requests the message generator 240 to transmit a message as a scene change event occurs. Then, the message generating unit 240 extracts the manager's mobile communication phone number from the storage unit 250, and sends a scene change event message in which the phone number is the called number to the manager's mobile communication terminal (S411).

According to the method of FIG. 4, when a person with impure intention changes the photographing angle of the camera or covers the camera lens with a foreign object, the intelligent image transmitting apparatus 200 transmits a scene change event to a remote management center 100. Informs that an abnormal shooting is in progress, and also sends a scene change event message to the administrator's mobile communication terminal so that prompt action is taken by the administrator.

Hereinafter, in the description with reference to FIGS. 5 and 6, the description overlapping with the description with reference to FIG. 3 or 4 will be compressed and described based on differences.

5 is a flowchart illustrating a method for detecting and reporting a theft event in an intelligent video transmission apparatus according to an embodiment of the present invention.

Referring to FIG. 5, when an image screen is collected by the image collecting unit 210, the filtering unit 230 filters the image screen by correcting noise, contrast, and the like on the image screen (S501 and S503). The filtering unit 230 provides the filtered video screen to the video analyzing unit 260, encodes the video screen, and transmits the encoded video screen to the management center 100 through the communication unit 220.

Next, the image analyzer 260 extracts the range information of the storage area of the valuables (eg, ceramics, art, etc.) and the image screen information (eg, RGB value or YUV component value) of the valuables from the storage unit 250. (S505). Subsequently, the image analyzer 260 extracts image information of the valuables storage area from the entire image screen based on the range information of the valuables storage area extracted by the storage unit 250, and stores the image information and the stored information in the storage unit 250. By checking the coincidence rate of the valuable image information, it is determined whether valuables located in the surveillance area is detected (S507).

If the matching rate of the image information extracted from the valuables storage area and the valuable image information of the storage unit 250 is less than the threshold value, the image analyzer 260 generates a theft event and transmits it to the management center 100 (S509). . Preferably, the image analyzer 260 continuously prepares for the case where the valuables are covered by the dynamic object, and the matching ratio between the image information extracted from the valuables storage area and the valuable image information of the storage unit 250 is determined for a predetermined time. Generate a theft event if it is determined to be less than the value. That is, the image analyzer 260 is hidden by the dynamic object in the valuables storage area in consideration of the situation that valuables located in the valuables storage area is not recognized for a short time, the valuables video screen and storage unit 250 extracted from the valuables storage area If the matching rate of the valuables image screen stored in the) does not continuously match for a predetermined time, theft event is generated and transmitted to the management center (100).

Next, the image analyzer 260 requests to transmit the theft event message to the message generator 240, and the message generator 240 extracts the manager's mobile communication phone number from the storage 250. Theft event message is set to the called number is sent to the administrator's mobile communication terminal (S511).

According to the method of FIG. 5, when the valuables located in the camera monitoring area are not detected, the intelligent video transmitting apparatus 200 transmits a theft event to a remote management center 100 to recognize the occurrence of theft of valuables. In addition, the administrator sends a theft event occurrence message to the administrator's mobile communication terminal so that prompt action is taken by the administrator.

The filtering unit 230 provides the corrected image screen to the image analyzer 260 and encodes the image screen to be transmitted to the management center 100 through the communication unit 220.

Next, the image analyzer 260 checks the moving object (ie, the dynamic object) based on the image screen provided by the filtering unit 230, and based on the area, height, and width of the object, the dynamic object Recognizes which group belongs to the car, man, or animal (S605). In this case, the image analyzer 260 recognizes the dynamic object by comparing the reference image screen of the storage unit 250 with the image screens sequentially provided from the filtering unit 230. That is, when a new object that does not exist in the reference video screen of the storage unit 250 exists in the video screen provided by the filtering unit 230, the image analyzer 260 newly enters the object into the camera monitoring area. The object is recognized as an object, and when the motion of the object is detected on another video screen provided from the filtering unit 230, the object is recognized as a dynamic object.

Next, the image analyzer 260 checks the range information of the event region in the storage 250, and extracts an image screen corresponding to the range of the event region from the entire image screen corrected by the filtering unit 230 ( S607). Next, the image analyzer 260 analyzes the image screen to determine whether a dynamic object has entered the event area (S609).

When the dynamic object enters the event area, the image analyzer 260 checks whether the event area is an area set as a prohibited area and, if the area is set as a prohibited area, sends the prohibited area entry event to the management center 100. A request is made to send the message to the prohibited area entry event message to the message generator 240 (S611 and S613). Then, the message generating unit 240 extracts the manager's mobile communication phone number from the storage unit 250, and sends a prohibited area entry event message in which the phone number is set as the called number to the manager's mobile communication terminal (S615). .

On the other hand, if the event area is not the area set as the prohibited area, the image analysis unit 260 generates the appear event and transmits to the management center 100 (S617).

Meanwhile, if the dynamic object entering the event area is continuously detected during the time set in the event area, the image analyzer 260 transmits the roaming event to the management center 100. In detail, the image analysis unit 260 appears after transmitting to the event management center 100, and extracts the video screen of the event region from the video full screen continuously provided from the filtering unit 230, each video screen If the dynamic object is continuously present in the event area for a predetermined time (for example, 10 minutes), the roaming event is transmitted to the management center 100 through the communication unit 220.

In addition, the image analyzer 260 transmits the disappearance event to the management center 100 when the dynamic object entering the event area is not detected in the event area. In detail, the image analyzing unit 260 appears after transmitting to the event management center 100, extracting the image screen of the event area from the image full screen provided by the filtering unit 230, and analyzing the corresponding video screen. If it is determined that the dynamic object does not exist in the event area, a disappear event is generated and transmitted to the management center 100.
