Abstract

Recently, governmental authority and local government are looking for a method of utilizing location information of smart phone for urgent rescue in fire and kidnap situation. Under this background, in this study, a method of rapidly collecting, constructing location determination based Wi-Fi AP data utilizing location information of smart phone and mobile mapping system was suggested in order to construct precise positioning information that could be utilized under urgent situation. By performing compensation work for GPS/INS/DMI through collected outcome, position of collected vehicle was acquired. In addition, source data integrating Wi-Fi information and collected position by coupling based on Wi-Fi AP collector and GPS time was constructed and Wi-Fi radiomap was constructed by removing Wi-Fi signal noise that reduces precise position performance. As a result of performing location determination performance assess ment by selecting 10 test positions by each local government, result value of 25.46cm for total local government average and 27.76m for SD could be obtained. It is considered that this result could be utilized as a technology of being able to supplement or substituting GPS location determination technology that is impossible in plocation determination of mobile communication company's base station (200m~2km) and indoor being used at present.

최근 정부기관 및 지자체에서는 화재, 납치 등 긴급구조에 스마트폰의 위치정보를 활용하기 위한 방안을 모색하고 있는 실정이다. 이에 본 연구에서는 긴급상황에서 활용 가능한 정밀측위정보를 구축하기 위해 스마트폰 위치정보와 mobile mapping system을 활용하여 정위치 기반의 Wi-Fi AP 데이터를 신속하게 수집 구축할 수 있는 방안을 제시하였다. 수집된 성과를 통해 GPS/INS/DMI에 대한 보정작업을 실시하여 정확한 수집차량의 위치를 취득하였다. 또한 Wi-Fi AP 수집기와 GPS 시각을 기준으로 커플링하여 Wi-Fi 정보와 수집위치를 통합한 원시데이터를 구축하고, 측위성능을 저하시키는 Wi-Fi AP 신호의 잡음 제거를 통해 Wi-Fi radiomap을 구축하였다. 각 자치구별로 10개의 테스트 지점을 선정하여 측위성능평가를 실시한 결과, 전체 자치구 평균은 25.46m, 표준편차는 27.76m의 결과 값을 얻을 수 있었다. 이러한 결과는 현재 사용하고 있는 이동통신사 기지국 측위(200m~2km)와 실내에서 불가능한 GPS 측위기술을 보완하거나 대체할 수 있는 기술로서 활용 가능할 것으로 판단된다.
