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

Abstract

The invention discloses a high-precision dynamic map data processing system and method based on road side sensors. The high-precision dynamic map data processing system comprises a map data acquisition terminal and a high-precision map generation service terminal. The map data acquisition terminal provides a bulk of diversified map road original data for the high-precision map generation service terminal; the high-precision map generation service terminal comprises a map data processing module and a map generation visual module; the map data processing module is used for extracting road features from the map road original data and carrying out hierarchical design on all the road features, splicing information of the same road, completing road feature data fusion on the road feature aspect first, finally completing image splicing on the image aspect, and generating a road downward projection drawing in dependence on the splicing result; and the map generation visual module is used for marking road information on the downward projection drawing, the marked road information and the downward projection drawing commonly form map data of a high-precision map, visual editing is carried out on the map data, and a high-precision dynamic map is generated. According to the invention, the generation cost of the high-precision map can be reduced, and the high-precision dynamic map can be updated quickly.

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...
