GPS 휴대폰을 이용한 차량경로용 도로망 데이터베이스 수정 방안

초록

As the use of vehicle route application and LBS (location based service) are fast grew, the importance of maintaining road network data is also increased. To maintain road data accuracy, we can collect road data by driving real roads with probe vehicle, or using digital image processing for the extraction of roads from aerial imagery. After compare the new road data to current database, we can update the road database, but that job is mostly time and money consuming or can be inaccurate. In this paper, an updating method of using GPS (global positioning system) enabled cell phone is proposed. By using GPS phone, we can update road database easily and sufficiently accurately.
