Abstract

The invention discloses a dynamic map providing method and device and a service platform, and belongs to the field of vehicle-road cooperation. The method mainly comprises the following steps: splitting and slicing a map in a predetermined area according to a predetermined slicing rule to obtain site map element data of at least one V2X roadside equipment site; performing registration according to the site map element data and a dynamic event sensed by the corresponding V2X roadside equipment site to obtain a site dynamic map; and sending the station dynamic map to a corresponding vehicle by using a related V2X roadside equipment station, and converting a station dynamic map message set into a map form required to be displayed by a human-computer interaction interface at a vehicle terminal for visualization. The dynamic map is provided for the vehicle through the V2X roadside equipment, so that the information obtained by the vehicle is richer, the beyond-visual-range sensing and positioning capability is provided for the vehicle, and the driving safety of the automatic driving vehicle can be improved.

Description

technical field [0001] The present invention relates to the field of automatic driving and vehicle-road coordination, in particular to a method, device and service platform for providing a dynamic map. Background technique [0002] There are many kinds of road environment perception solutions in the existing technology. At present, the perception solution of pure vision + millimeter wave radar is mostly praised. Its advantage is low cost, which is convenient for large-scale commercial production. However, when applied to autonomous driving, the above-mentioned perception scheme has the defects of limited perception range, and perception accuracy is affected by the environment with different light intensities. Therefore, the perception solutions of most autonomous driving companies in China are also more inclined to laser plus high-precision maps plus V2X. [0003] Lidar perception is less affected by the environment, V2X can achieve over-the-horizon perception, and high-pre...
