Abstract

It is necessary to develop a next generation location referencing method with higher accuracy as advanced technologies such as autonomous vehicles require higher accuracy of location data. Thus, we proposed a framework for a lane-level location referencing method (L-LRM) based on high-precision digital road network map, and developed a tool which is capable of analyzing and evaluating the proposed method. Firstly, the necessity and definition of location referencing method was presented, followed by the proposal of an L-LRM framework with a fundamental structure of high-precision digital road network map for the method. Secondly, an architecture of the analysis and evaluation tool was described and then the Windows application program was developed using C/C++ programming language. Finally, we demonstrated the performance of the proposed framework and the application program using two different high precision digital maps with randomly generated road event data.

최근 자율주행차와 같이 고정밀의 위치 정확도를 요구하는 기술이 개발됨에 따라 정확도가 높은 위치정보 교환 기술 또는 위치참조방법 개발의 필요성이 대두되고 있다. 이에 본 연구는 정밀전자지도를 이용하는 차로 수준의 위치참조방법 프레임워크를 제안하고, 새로운 위치참조방법을 구현, 분석 및 평가할 수 있는 툴(tool)의 설계 및 개발을 목적으로 한다. 이를 위해 위치참조방법의 필요성과 정의, 그리고 정확도 높은 위치 정보의 교환을 위한 정밀전자지도의 기본 구조를 제안하고, 이를 기반으로 차로 수준의 위치참조방법을 위한 프레임워크를 제시하였다. 프레임워크의 실제 구현 및 테스트, 분석을 위해 필요한 분석 평가 툴을 개발하기 위해 기본 아키텍처 설계 및 그에 따른 실제 C/C++ 기반의 윈도우 응용 프로그램 개발을 수행하였다. 마지막으로 분석 평가 툴을 이용해서 이종 정밀전자지도 간의 위치 정보를 교환하는 테스트를 통해 그 실효성을 검증하였다.
