High definition (HD) maps play a very important role in the realization of autonomous driving technology. It assists self-driving vehicles to efficiently and safely complete a series of driving decisions and route planning by virtue of having most of the accurate and reliable prior information in the road environment. With the continuous change of technology, there are higher requirements for the accuracy, richness and freshness of the information stored in the HD map, so as to assist the practical application of automatic driving technology. However, current research related to HD maps mainly focuses on static information in the road environment. Since there is a large amount of complex, variable and uncertain dynamic information in the road environment, it can be used as prior knowledge for self-driving to make better decisions. Therefore, the research focus of this paper is on the dynamic information. We propose to use HD map as an information system - high definition map information system (HDMIS) - to assist autonomous driving vehicles. We design the specific content of dynamic information in the HDMIS, and develop an information interaction approach based on the vehicle end of the self-driving car and the HDMIS cloud as the interactive subject of dynamic information. In the experiment, we design and build three types of specific traffic scenarios on the simulation platform, and verify the effectiveness of the interaction approach by using the database to perform information interaction between different ports. The results show that our interaction approach can meet the storage and release of dynamic information by HDMIS to a certain extent, and can provide a large amount of dynamic information for autonomous vehicles to help them complete subsequent driving decisions and planning.

I made a presentaion about our group recently research on HD Map Information Interaction at the branch venue of Mobile Mapping Technologies 4: Mobile Mapping Technologies and HD Maps, on 4th September, 2023. The below figure shows the conference site at that time.
During the conference, Professor Wei Huang led the team members to attend the conference, where they engaged in in-depth discussions with scholars from around the world on topics related to human mobility patterns and high-definition maps.
