Abstract

The main functionality of occupancy sensors is to determine the existence of humans in the space. If the space is occupied, a light is on and for vacancy, the light automatically turns off. In this letter, the functionality is realized by the utilization of color information. The color information of incoming people is saved. For outgoing people, their color distribution is compared with the saved information, thus providing the recognition of the outgoing people. For the comparison, four similarity metrics are examined to validate the proposed method.

점유센서의 주요 기능은 공간에 사람이 존재하는지를 결정하는 것이다. 사람이 있으면 점등하고, 반대이면 소등하게 된다. 모션 검출, 객체 추적 등의 방법이 있지만, 본 레터에서는 이 기능의 구현에 컬러를 활용한다. 사람의 컬러정보를 이용하여 입실하는 사람들의 정보를 저장하고, 퇴실하면 저장된 컬러정보와 비교하여 퇴실하는 사람을 인식하는 기법이다. 4가지 유사성 메트릭을 이용하여 성능을 검증하였다.
