This application is a National Phase application of International Application No. PCT/KR2018/000975 filed Jan. 23, 2018, which claims benefit of priority to Korean Patent Application No. 10-2017-0010702 filed Jan. 23, 2017, the entire content of which is incorporated herein by reference.
The present invention relates to a method and system for tracking an object of interest in real-time in a multi-camera environment, and more specifically, to a method and system for tracking an object of interest in real-time in a multi-camera environment in which cameras are capable of performing data communication without overlapping each other.
Recently, as importance of security has increased with development of information and communications technology, in general, the information and communications technology is applied to a capturing means such as a closed-circuit television (CCTV) such that intelligent CCTV technology, in which image information can be viewed remotely in real-time anytime and anywhere by any terminal that has been qualified in advance, is becoming popular.
FIG. 1 is a schematic configuration diagram of a system for tracking an object of interest in a multi-camera environment according to an embodiment of the present invention.
FIG. 2 is a simplified cross-sectional view for describing processes of setting and resetting a subnetwork under a multi-camera environment, which is an environment in which the present invention is applied.
FIG. 3 is a functional diagram for describing components of a system for tracking an object of interest in a multi-camera environment according to an embodiment of the present invention.
A method for tracking an object of interest in a multi-camera environment according to the present invention, which is a method for tracking an object of interest in a multi-camera environment, the method including selecting, by a server module, a subnetwork in the multi-camera environment, receiving, by a client module, subnetwork configuration information from the server module, receiving, by the client module, image frames from one or more cameras constituting the subnetwork in a first time interval, determining a camera in which an object of interest is present on the basis of the received image frames and locally tracking the object of interest for the image frame from the determined camera, and re-identifying the object of interest of the one or more cameras constituting the subnetwork when the object of interest disappears from the image frame of the determined camera.
Specific structural and functional descriptions of embodiments of the present invention disclosed in this specification are only for the purpose of describing embodiments of the present invention, and the embodiments of the present invention may be embodied in various forms and should not be interpreted as being limited to the embodiments described in this specification.
While the present invention is open to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. However, it should be understood that there is no intent to limit the present invention to the particular forms disclosed, and on the contrary, the present invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention.
