Abstract: This paper takes autonomous driving and driverless as the research object, discusses and defines intelligent high-precision map. In this paper, intelligent high-precision map is considered as a key link of future travel, and a carrier of real-time perception of traffic resources in the entire space-time range, and the criterion for the operation and control of the whole process of the vehicle. As a new form of map, intelligent high-precision map has distinctive features in terms of cartography theory and application requirements compared with traditional navigation electronic maps. In order to promote the development of research and application of intelligent high-precision map, it is necessary to analyze and discuss its key features and problems. This paper proposes the information transmission model from the cartography theory; combines the wheeled robot's control flow from practical application, proposes the data logic structure of intelligent high-precision map, and analyzes its application in autonomous driving; summarizes the computing mode of "crowdsourcing+edge-cloud collaborative computing", and carries out key technical analysis on how to improve the quality of crowdsourced data; analyzes the effective application scenarios of intelligent high-precision map in the future; Finally, presents some thoughts and suggestions for the future development of this field.

Key words: intelligent high-precision map, information transmission model, data logic structure, user model, computing mode, edge-cloud collaboration
