Zusammenfassung:The present invention relates to a system for generating and distributing quality evaluation scores of precise road maps. According to the present invention, when precise road maps, which are an essential requirement for autonomous driving, are built and provided, there is a limitation in that there is always a positional accuracy error and recognition error of sensors forming a mobile mapping system (MMS) and it is determined that data quality can be affected by a vehicle condition and external environmental factors during investigation. Accordingly, a quality score of precise road map data by synthesizing information on internal/external environmental factors and the score is provided together with the precise road map data distributed to autonomous vehicles, and thus the autonomous vehicle supplied with a precise road map can reflect the precise road map in a control mode thereof by referring to reliability of the corresponding data. The system comprises a collection unit, a digitization unit, a quality score generation unit, and a distribution unit. 본 발명은 정밀도로지도 데이터의 품질평가 점수 생성 및 배포 시스템에 관한 것으로써, 자율주행에 필수 요건인 정밀도로지도를 구축 및 제공하는데 있어 MMS를 구성하는 센서들의 위치정확도 오차 및 인식 오류 등이 상시 존재한다는 한계점이 있고, 조사시 차량상태와 외부적인 환경 요소들에 의해서도 데이터 품질에 영향을 끼칠 수 있다고 판단되는 바, 내/외부적 환경요소 정보들을 종합하여 정밀도로지도 데이터의 품질점수를 생성하고, 해당 점수를 자율차에 배포되는 정밀도로지도 데이터와 함께 제공함으로써 정밀도로지도를 공급받는 자율차에서 해당 데이터의 신뢰도를 참고하여 자율차의 제어모드에 반영할 수 있다.
