Description

System for providing video service using security surveillance camera and method thereof {System and method for providing image service using security camera}

The present invention relates to a video service providing system using a security surveillance camera and a method thereof. More specifically, the present invention generates a background image from the image obtained for each frame through various methods such as subtraction of neighboring frames from the image and a method of comparing and correcting the basic background frame and the current frame, and the respective frames and the background image are generated. After extracting the objects except the background image from each frame by comparing or subtracting the images of the neighboring frames, the IDs are assigned to the extracted objects, and the object image, the object movement time, By adding a local image control unit to the local security surveillance camera having a function of listing object information on other object attributes such as local terminal ID, elderly person, child, woman, man, and key, each local image control unit extracts the extracted ID. Transmitted individualized information to the integrated management server, and the integrated management server manages the By integrating various information, only the object information having the desired object property can be extracted and inquired, so that the user can search the moving path through the information of the desired object, and the local security surveillance camera provides low-resolution video information in normal times. When the request of the integrated management server, can provide high-definition (HD class) video information, and provides a video service providing system and method using a security surveillance camera that can solve network traffic and storage problems will be.

Security surveillance cameras are widely installed in residential districts, roads, and other facilities, making them an effective means of crime prevention. In general, a security surveillance camera is installed in a plurality of cameras to be monitored to receive images of a plurality of surveillance areas in real time has a form that the operator monitors in the central control room.

The conventional security surveillance camera has a problem in that all the image records must be searched to find an object having an object attribute such as an elderly person, a child, a woman, a man, and a key in an image.

In addition, the conventional security surveillance cameras mostly provide low-resolution video, so the local video cannot be seen clearly, and in the case of security surveillance cameras that provide some high-resolution video, problems of network traffic and storage are found. There was this.

Therefore, after generating objects by generating a background image for each frame from an image, comparing the background images with each frame, and extracting the background image from each frame, and assigning IDs to the extracted objects, respectively, By adding a local video control unit to the local security surveillance camera, the local video control unit having a function of listing object information on object video, object travel time, local terminal ID, and other object attributes such as elderly, children, women, men, and keys The image control unit transmits the extracted ID information to the integrated management server, and the integrated management server can extract and search only the object information having the desired object property by integrating various information of several local security surveillance cameras. You can search for the movement route through the information of the object. Provides resolution-level video information and, when requested by the integrated management server, can provide high-definition (HD-level) video information, and relatively small network information is transmitted to the management server for the necessary information for monitoring. Since it requires traffic, it is a suitable method for the situation that the development of a video service providing system and method using a security surveillance camera that can solve the network traffic and storage problems.

Therefore, in order to solve the above problems, the basic object of the present invention is to generate a background image for each frame through various methods such as subtraction of neighboring frames from a video and a method of comparing and correcting a basic background frame and a current frame, and for each frame. Compares the background image with each other, extracts the objects except the background image from each frame, and assigns IDs to the extracted objects, and the object image, object movement time, local terminal ID and the elderly, children, women, By adding a local video control unit having a function of listing object information about other object attributes such as a man and a key to the local security surveillance camera, each local video control unit transmits the extracted ID information to the integrated management server. The integrated management server integrates various information from several local security surveillance cameras The present invention provides a system and method for providing a video service using a security surveillance camera capable of extracting and inquiring only object information having body properties and searching for a movement path through information of a desired object.

Another object of the present invention is to provide a low-resolution video information for the local security surveillance cameras in general, and when requested by the integrated management server, can provide high-definition video information (HD class), network traffic and storage (Storage) To provide a video service providing system and method using a security surveillance camera that can solve the problem.
