Abstract

The safe return home system automatically tracks and makes a video-recording the client by selecting and controlling CCTV cameras near the client using GPS location information received from the smart device possessed by the service client. This service helps clients to return home safely when there is a crime-ridden district on their late night return home route. If the CCTV cameras that can capture the client are already occupied and used by other clients, concession of occupied CCTV cameras is required to capture the new client. To tackle the limitation, we developed an extended method that considered both the average distances between the client and CCTV cameras and the service rates. As a result, the average distance between CCTV cameras and clients is kept close, and service rates are improved.

안심귀가 시스템은 서비스 의뢰인이 소지한 스마트 기기로부터 수신된 GPS 위치정보를 이용하여 의뢰인 근처의 CCTV 카메라들을 선택하고 제어함으로써, 의뢰인을 자동으로 추적하고 영상을 촬영한다. 이 서비스는 심야에 귀가하는 경로 상에 우범지역이 존재할 때 의뢰인의 안심귀가에 도움을 제공한다. 의뢰인을 촬영할 수 있는 CCTV 카메라들이 다른 의뢰인에 의하여 이미 점유되어 사용되는 경우, 새로운 의뢰인의 촬영을 위하여 점유된 CCTV 카메라의 양보가 필요하다. 본 논문에서는 의뢰인과 CCTV 카메라 사이의 평균 거리와 서비스율을 모두 고려한 개선된 방법을 제안한다. 그 결과, CCTV 카메라와 의뢰인간의 평균거리가 가깝게 유지되며, 서비스율도 개선된다.
