摘要：Navigation systems have become an interesting research and industrial topic due to their wide deployment. The method of updating the map database (DB) with previously unknown map information has become an important factor in navigation system design. At present, multiple map DB providers maintain their own datasets and work to reduce unknown map information in only their proprietary maps. Map updating systems can generally be divided into two fields: position and traffic sign detection, and network and cloud based map generation and updating. This paper introduces the main difficulties associated with determining and updating unknown map information and briefly surveys the state-of-the-art technologies in this field. Further discussion on potential trends in the development of unknown map information is also provided.
