Abstract: As the national strategic task for the innovation and development of intelligent vehicles is put forward and advanced, high-precision map has become a research focus in recent years. While high-precision map as a core element in automatic driving has been widely studied in many fields such as surveying and mapping, comprehensive theoretical research of its development status is still lacking. In this study, the definition of high-precision map and analysis on its comparison with traditional digital maps are firstly introduced. Then the main research and related works are divided into three categories, from the aspects of data structure, data production, function and application of high-precision map which are elaborated and summarized. From the perspective of data structure, high-precision map includes static map data and dynamic map data, with the former being the focus. In consideration of the level of data production, the production mode, process and specific technical methods of high-precision map are respectively analyzed. It is believed that the combination of professional department guidance and crowd-sourcing will be the basic feature of data production in the future. Then the key technologiesin high-precision map application are summarized, which play an important role in positioning and navigation of automatic driving.Some prospects about high-precision map and its future research are also made.

Key words: high-precision map, data structure, data production, function and application, automatic driving
