Abstract
보안이 중요시되는 공간에서 임의의 사람을 추적하고 인식할 수 있는 시스템의 필요성이 점차 중요시되고 있다. 본 논문에서는 wide-area를 감시하기 위해 음원과 Pan-Tilt 카메라를 이용하여 침입자 추적 시스템을 구현하고자 한다. 먼저 음원추적 센서를 이용하여 음원의 방위를 검출한 후 Pan-Tilt 카메라를 방위 방향으로 이동시키고 이동된 Pan-Tilt 카메라로부터 기준영상을 추출한 후 일정 기준 시간마다 영상을 다시 획득하여 차 영상과 검출결과를 얻어 침입자를 추적하여 감시 시스템을 구현한다. 본 논문에 의해서 구현된 시스템은 흠 네트워크 보안 시스템과 연동을 하여 가정이나 공공시설 보안에 대한 인터페이스 역할을 할 수 있다. In the place that its security is crucial, the necessity of system which can tract and recognize random person is getting more important. In this paper, we'd like to develop the invader tracking system which consists of the sound source tracking-sensor and the pan-tilt camera for wide-area guard. After detecting the direction of any sound with the sound source tracking-sensor at first, our system make move the pan-tilt camera to that direction and extract reference image from that camera. This reference image is compared and updated by the next captured image after some interval time. By keeping on it over again, we can realize the guard system which can tract an invader using the difference image and the result of another image processing. By linking home network security system, the suggested system can provide some interfacing functions for the security service of the public facilities as well as that of home.
