Description

[0001] Image security system and method using mobile terminal [

The present invention relates to an image security system and method using a terminal identifier. More particularly, the present invention relates to a system and method for identifying an object corresponding to a position of a terminal through a plurality of beacons installed in a surveillance region of a camera, To a corresponding object to facilitate tracking of the object, and to output a directional acoustic signal corresponding to the object in which the event occurs to provide a security for the surveillance area, And methods.

Along with the development of camera and image processing technology, the development of security system that continuously identifies and tracks the object designated by the user through the image analysis of the image acquired through the camera and provides information about the object in which the event occurs ought.

However, the existing security system only specifies and tracks the object of interest identified in the image of the camera only through the image, and it is difficult to accurately correspond the point where the object of interest is located in the region corresponding to the surveillance region of the camera.

Accordingly, after the manager confirms the external features of the object of interest through the image, the manager directly searches for the object to be monitored corresponding to the object of interest in the monitoring area, thereby determining the point where the object of interest is located in the monitoring area There is a problem that it is difficult to promptly perform an action on an object of interest.

In other words, the existing security system not only has difficulties in mapping the object of interest shown in the image in the real area, but also provides no means to support the contact to the object of interest corresponding to the object of interest, There is a difficult problem.

In addition, the recent security system uses a method to identify objects in an image through a machine learning method and to continuously observe whether or not the same object is used when tracking the same object as a method for effectively confirming the same object. However, There is a problem that the complexity of the algorithm for object tracking and the processing load are too high because the object recognition technology detects objects similar to the learned objects based on the entire image.

In addition, when the monitored object corresponding to the object of interest moves in different areas corresponding to each of the plurality of surveillance cameras, the existing security system detects the object of interest identified in the image provided by one of the cameras, , It is often the case that the object tracking is failed due to the problem that the accuracy is low due to the error that occurs in the image analysis, so that the reliability of the security system There is a falling problem.
