초록

급속히 늘어난 스마트폰의 보급은 인간의 라이프 스타일 변화에 영향을 미치고 있으며, 스마트폰 기반 위치정보는 실내외 공간에서 다양한 편의성 서비스를 제공할 수 있는 환경을 마련하고 있다. 특히, GPS 정보가 제공되고 있지 않은 지하공간의 경우에서 위치 기반 서비스가 제공된다면 정보약자와 교통약자를 위한 길 찾기와 길 안내 등 많은 편의를 제공할 수 있다. 그러나, 지하철 역사에서 길 안내 서비스 구현은 측위 정확도를 확보하는 것은 여전히 어려운 과제이다. 본 연구는 지하철 역사에서 실내 내비게이션을 위해 선행되어야 하는 모든 과정을 하나의 시스템에서 수행할 수 있도록 융합 측위 알고리즘과 함께 연속 측위에서 사용하는 새로운 보행자 걸음 인식기법을 개발하고, 평가하고 있다.

Rapid increasing of smartphones has changed people's lifestyles, and location-based services are providing a platform to provide various conveniences in accordance with these changes. In particular, it may provide convenience to many users if location-based services are provided in an indoor area such as subway station. However, it is still a difficult task to ensure accurate positioning result for guiding routes in subway stations. This study proposes a KAI-R system that allows all processes to be performed in one system for indoor navigation in subway stations. The proposed system includes a new pedestrian step detection method for continuous positioning along with an improved fusion positioning algorithm.
