The invention provides a high-precision dynamic map generation method and device, and the method comprises the steps: transmitting request information to a remote terminal, and receiving a point cloud map, fed back by the remote terminal, of a target road section; inputting the collected roadside sensing information into a dynamic target recognition model to obtain a dynamic target recognition result, and extracting first target information of a target ground object when the dynamic target recognition result is the target ground object; receiving second target information sent by the target ground object; and acquiring a local dynamic map based on the first target information, the second target information and the point cloud map of the target road section. According to the high-precision dynamic map generation method and device provided by the invention, a local dynamic holographic high-precision map can be formed, and the accuracy and real-time performance of the map are improved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating a high-precision dynamic map. Background technique [0002] At present, with the rapid development of autonomous driving technology, the importance of high-precision maps has become increasingly prominent, and has become an indispensable part of realizing unmanned driving and intelligent transportation. The accuracy of existing navigation maps is generally road-level maps, which greatly simplifies the actual traffic environment, and can provide less information and lower accuracy. Ordinary map navigation accuracy can only reach meter level, high-precision map can be accurate to 10cm level, not only increases the data related to lane attributes, but also adds various types of elevated objects, guardrails, obstacles, road edge types, roadside landmarks, etc. type data. Multivariate and heterogeneous massive map data requires a large amount of ...
