VIDEO SURVEILLANCE APPARATUS USING DUAL CAMERA AND METHOD THEREOF
First Claim
1. A video surveillance apparatus using a dual camera, comprising:
- a dual camera unit including a visible light camera and a special-purpose camera which are adjacent to each other, the special-purpose camera having a property different from a property of the visible light camera;
a calibration unit which includes surveillance space calibration information for each camera of the dual camera unit;
a video analysis unit which analyzes a video of one selected from videos of the cameras of the dual cameras by referring to the calibration information;
a video matching unit which mutually matches videos of the two cameras of the dual camera unit by the medium of the surveillance space by using the calibration information for each camera of the calibration unit; and
a representation unit which selects a video of one to be analyzed by the video analysis unit, of the cameras of the dual camera unit according to an external control signal or a preset criterion, selects a video of a camera to be provided to the outside, and displays a result of the analysis of the video analysis unit on a corresponding position of the outside provision video matched through the video matching unit.

Abstract
The present invention relates to a video surveillance apparatus and method using a dual camera, which is capable of applying any camera videos with a result of video analysis made based on one selected from videos provided from a special purpose camera, such as a thermal image camera, and a visible light camera. Since the video surveillance apparatus and method is capable of arranging a visible light camera and a special-purpose camera in the same surveillance area, securing FOV differences between these cameras as pixel matching parameters between images by the medium of the same space corresponding to an image of each camera, performing selective video analysis for one of these parameters, and checking a result of the analysis in any camera images through the matching information in the same way, it is possible to guarantee autonomy of video switching, continuity of object tracking in video switching, and high reliability.
