Zusammenfassung:The present invention relates to an open door image detecting system using a pattern analysis of an alarm pattern sticker and a finder pattern sticker, and a method thereof. The open door image detecting system using a pattern analysis of an alarm pattern sticker and a finder pattern sticker comprises: a camera part which photographs a finder pattern sticker and an alarm pattern sticker, which are installed in a door, and transmits the photographed image information to a CPU; the CPU which receives the photographed image information from the camera part, measures a distance change of the finder pattern sticker and the alarm pattern sticker, caused by opening of the door, through the image information, calculates a diagonal matrix depending on the distance change and determines whether the door is open by using the diagonal matrix, and transmits an open door signal to an alarm part; and the alarm part receiving the open door signal from the CPU to provide an alarm. 본 발명 알람 패턴 스티커와 파인더 패턴 스티커의 패턴 분석을 이용한 문열림 영상 감지 시스템은 문에 설치되어 있는 파인더 패턴 스티커와 알람 패턴 스티커를 촬영하고 촬영된 영상 정보를 CPU로 전송하는 카메라부와, 카메라부에서 촬영된 영상 정보를 수신하고 상기 영상정보를 통하여 파인더 패턴 스티커와 알람패턴 스티커의 문 열림에 따른 거리 변화를 측정하고 거리 변화에 따른 대각선 행렬을 구하며 상기 대각 행렬을 이용하여 문열림을 판단하고 문열림 신호를 알람부로 전송하는 CPU와 상기 CPU로부터 문열림 신호를 수신하여 경보를 제공하는 알람부로 구성된 것을 특징으로 하는 것이다.
