Abstract

The roadmap DB update for unknown roads is a very important factor for car navigation systems. In this paper, we propose a cloud computing based roadmap generation method for use between heterogeneous navigation system for unknown roads. While the drivers drive on unknown roads, the proposed method extracts the road attribute information, and then generates the metadata in an XML format that is available for the heterogeneous navigation systems in a cloud environment. The metadata is proposed to be used as a replacement for conventional proprietary roadmap formats which used by roadmap providers, which is efficient for heterogeneous navigation system providers in a cloud computing environment. Then, this metadata is provided to the roadmap DB providers through the cloud computing interfaces. With the proposed method, the roadmap DB providers update the own roadmap DB for navigation systems in real time. Therefore, the proposed method can reduce the costs of an actual traveling test and the maintenance for the roadmap DB provides. Thus, the cloud-oriented road map generation method can more efficiently update the unknown road information.

지도 DB 업데이트 방법은 카 네비게이션을 사용하는 운전자 입장에서는 매우 중요한 요소이다. 본 연구는 클라우드 컴퓨팅 환경을 이용해 이기종 네비게이션 시스템을 사용하는 운전자들이 새로운 도로(Unknown Roads) 주행시 추출된 도로 속성 정보를 클라우드에서 분석해 이기종 네비게이션간 서비스가 가능한 XML 포맷의 Metadata를 생성한 다음, 이것을 모든 지도 정보 제공자(Provider)에게 제공하면 해당 Map DB 제공자는 클라우드로 부터 제공 받은 도로의 속성 정보 metadata를 자신의 네비게이션 시스템을 사용하는 모든 운전자의 Map DB를 실시간으로 업데이트하는 방법을 제안한다. 이 방법은 Map DB Provider들이 수행하는 실차 주행 테스트 비용을 줄이고 서버 자원 통합 구축을 통한 Map DB 데이터센터의 유지 비용을 줄일 수 있다. 결국 제안된 방법은 새로운 도로 정보를 모든 운전자들의 Map DB에 더욱 효율적으로 업데이트할 수 있다.
