Abstract

People counting has always been a method of interest for maximizing energy saving by identifying the congestion level or amount of use of a specific facility to efficiently manage the facility, or automatically implementing a power saving function by identifying the number of people entering and exiting a specific place such as a toilet. The method of counting people by image processing is very expensive and has the disadvantage of being severely affected by the surrounding environment of the lighting. In the case of the area sensor, there is a disadvantage of counting as one person when the number of people passes close with arms folded. In order to solve the existing method, which is expensive, affected by lighting, or inaccurate the number of people in certain cases, this paper proposes a new method of counting people using the principle of LiADAR. Accurate counting of the number of people entering the hospital will help manage hospital facilities, but it will also help to establish effective quarantine measures at the present time when Corona 19 is prevalent.

인원계수는 특정 시설의 혼잡도나 이용량을 파악하여 시설을 효율적으로 관리하거나 화장실 등 특정 장소의 출입인원을 파악하여 자동으로 절전기능을 구현함으로써 에너지 절약을 최대화하기 위한 용도로 늘 관심있는 방법이었다. 영상처리에 의한 인원계수 방법은 매우 비용이 비싸며 조명의 주위환경에 심하게 영향을 받는 단점이 있고 area sensor의 경우 인원이 팔짱을 끼고 근접하여 통과할 경우 1명의 인원으로 계수하는 단점이 있다. 비용이 비싸고 조명에 영향을 받거나 특정한 경우 인원계수가 부정확한 기존의 방법을 해결하기 위하여 본 논문에서는 라이다(LIADAR)의 원리를 이용한 새로운 인원계수 방법을 제안한다. 병원 출입인원을 정확하기 계수하는 것은 병원시설을 관리하는 데도 도움이 되겠지만 코로나19가 만연한 현시점에서 효율적인 방역대책을 세우는 데도 도움이 될 것이다.
