Abstract

Smart care surveillance system can take the position information of the user and monitor by controlling neighbor CCTVs using GPS receiver built into smart device. But because the position information contains a significant error, in general smart device, it is necessary to be corrected for precise monitoring. In previous smart care system, this error is corrected by using a plurality of CCTV. But it has disadvantage that two or more CCTVs pointed toward the same point at the same time. In this paper, we propose the method to correct error of the GPS location information by using only one CCTV. With experiment result, we find that the accuracy of GPS location information corrected with only one CCTV is as improved as two CCTVs.

스마트 케어 감시 시스템은 스마트 디바이스에 내장된 GPS 수신 기능을 사용하여 이용자의 위치 정보를 획득하고 주변의 CCTV를 제어하여 이용자를 추적하는 시스템이다. 그러나 일반적인 스마트 디바이스의 GPS 위치 정보는 상당한 오차를 포함하고 있기 때문에 추적을 원활히 하기 위하여 GPS 위치 정보의 보정을 필요로 한다. 기존의 스마트 케어 시스템에서는 두 대 이상의 CCTV를 이용하여 이러한 GPS 위치 정보 오차를 보정하였다. 그러나 이러한 방법은 반드시 두 대 이상이 동일한 지점을 촬영해야 하는 단점이 있다. 본 논문에서는 위치 정보의 오차를 보정하기 위하여 단지 하나의 CCTV만을 이용하는 새로운 방법을 제안한다. 실험 결과, 하나의 CCTV만을 이용하더라도 두 대의 CCTV를 이용한 위치 정보 보정방법 만큼 정확도가 향상되었음을 확인할 수 있다.
