Camera tracing and surveillance system and method for security using thermal image coordinate
First Claim
1. A camera tracing and surveillance system for security using a thermal image coordinate, the system comprising:
- an infrared thermal image camera for capturing a thermal image of a predetermined surveillance area and providing the captured image as a thermal image to extract a position coordinate of a target;
a tracing and surveillance camera for tracing the target within the predetermined surveillance area, enlarging an image of the target and capturing the enlarged image;
a position control device for performing position control of the tracing and surveillance camera based on the position coordinate of the target extracted from the thermal image of the surveillance area to allow the tracing and surveillance camera to trace the target within the surveillance area; and
a control system for identifying the target in the surveillance area and extracting the position coordinate of the target by performing image processing of binarizing the thermal image of the surveillance area captured by the infrared thermal image camera based on a threshold, for controlling driving of the position control device based on the position coordinate of the target extracted from the thermal image of the surveillance area, and for receiving and storing an image for identification of the target captured by the tracing and surveillance camera.

Abstract
A camera tracing and surveillance system and method for security using a thermal image coordinate, whereby an image having high resolution for identification in which a person can be accurately identified within a surveillance area and identity of the person can be accurately checked, can be obtained using a simple algorithm.
To this end, the person within the surveillance area is identified and a position coordinate of the person is extracted from a thermal image captured by a thermal image camera, and a tracing and surveillance camera traces the person, enlarges an image of the person, and captures the enlarged image based on the extracted position coordinate so that an image having high resolution for identification can be obtained.

6. A camera tracing and surveillance method for security using a thermal image coordinate, the method comprising:
-
capturing a thermal image of a predetermined surveillance area and providing the captured image as a thermal image to a control system using an infrared thermal image camera; identifying a target in the surveillance area and extracting a position coordinate of the target by performing image processing of binarizing the thermal image of the surveillance area captured by the infrared thermal image camera based on a threshold using the control system; controlling driving of a position control device based on the position coordinate of the target extracted from the thermal image of the surveillance area by the control system; when the position control device is driven, tracing the target within the predetermined surveillance area, enlarging an image of the target and capturing the enlarged image using a tracing and surveillance camera; and receiving and storing an image for identification of the target captured by the tracing and surveillance camera using the control system. - View Dependent Claims (7, 8, 9, 10)
