Abstract

As the 4th Industrial Revolution era in worldwide, interest in autonomous vehicles is increasing. but due to recent safety issues such as pedestrian accidents and car accidents, as a technical model for this, the demand for 3D HD maps (High Definition maps) is increasing in including lanes, road markings, road information, traffic lights and traffic signs etc. However, since some complementary points have been continuously raised according to demand, It is necessary to collect the opinions of institutions and companies utilizing HD maps and to improve HD maps. This study was conducted by utilizing the results of the contest for usability verification of HD Maps hosted by the National Geographic Information Institute and organized by the Spatial Information Industry Promotion Institute. For this study, we researched HD maps' layers and codes for HD maps object usability to improve HD maps, constructed HD maps object usability items accordingly, and contested usability verification of HD maps according to the items The contestants conducted verification and analyzed the results. As a result, the most frequently used code for each layer was the flat intersection, and the code showing the highest usage rate was a safety sign. In addition, the use rate of the sub-section and height obstacles was 16.67% and 8.88%, respectively, showing a low ratio. In order to utilize HD maps in the future, this study is expected to require research to continuously collect opinions from customers and improve data objects and data models that are actually needed by customers.

세계적으로 4차 산업혁명 시대에 접어들면서 자율주행차에 대한 관심이 증대되고 있으나 최근 보행자사고, 차대차사고 등 안전 확보 등의 이슈로 이에 대한 기술적인 모델로서 차선, 노면표시 등 도로정보와 신호등, 교통표지판 등 시설물 정보가 포함된 3차원 정밀도로지도(HD Map: High Definition Map) 수요가 높아지고 있다. 하지만, 수요에 따른 일부 보완점들이 계속적으로 제기되고 있어, 정밀도로지도를 활용하는 기관·기업들의 의견을 수렴하고 그에 따른 정밀도로지도의 개선이 필요한 실정이다. 본 연구는 국토지리정보원에서 주최하고 공간정보산업진흥원에서 주관했던 정밀도로지도 활용성 검증 공모전의 결과를 활용하여 연구를 수행하였다. 본 연구를 위해서 정밀도로지도의 개선을 위한 정밀도로지도 객체 검증을 위해 정밀도로지도의 레이어 및 레이어 코드를 조사하고, 그에 따라 정밀도로지도 객체 검증 항목을 구성하였으며 그 항목에 따라 정밀도로지도 활용성 검증 공모전 참가자들이 검증을 수행하고, 그 결과를 분석하였다. 그 결과 참가자들이 가장 많이 사용한 레이어별 코드는 평면교차로 등이며, 가장 높은 사용률을 보여주는 코드는 안전표지로 나타났다. 또한 부속구간 및 높이 장애물의 사용률은 각각 16.67%, 8.88%로 낮은 비율을 보여주었다. 이번 연구로 향후 정밀도로지도의 활용을 위해서 지속적으로 수요처의 의견을 수렴하여 수요처에서 실제로 필요한 레이어와 이에 대한 데이터 모델을 개선하는 연구가 필요할 것으로 예상된다.
