High-precision dynamic map data processing system and method based on roadside sensors

Abstract

The invention discloses a system and method for processing high-precision dynamic map data based on roadside sensors. The system includes: a map data acquisition terminal, which provides massive and diversified original map road data for a high-precision map generation server; high-precision The map generation server includes: a map data processing module, which extracts road features from the original road data of the map, adopts a layered design for all road features, splices the same road information, and first completes road feature data fusion at the road feature level, and finally The image stitching is completed at the image level, and the result of the stitching generates a top-view projection map of the road; the map generation visualization module marks the road information on the top-view projection map, and the marked road information and the top-view projection map together form the map data of the high-precision map. Visually edit map data to generate high-precision dynamic maps. The invention can reduce the generation cost of the high-precision map and realize the fast updating of the high-precision dynamic map.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a high-precision dynamic map data processing system and method based on roadside sensors. 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 not high, and the entire road is used as an object to provide road information data or issue navigation instructions. This kind of navigation map is called a road-level map, which greatly simplifies the actual traffic environment and can provide The information content is small, the accuracy is low, and the ability to assist the driver is low. [0003] The map required for autonomous driving must not only have high precision, but also have a large number of rich det...
