Abstract

The invention provides a map data updating method, device and system and a storage medium, and the method comprises the steps: determining a road section identifier of a to-be-updated road section ina map; sending data acquisition indication information to an unmanned vehicle, wherein the data acquisition indication information comprises a road section identifier and the current acquisition frequency of a road section corresponding to the road section identifier; receiving road section information corresponding to the road section identifier sent by the unmanned vehicle; obtaining a road section updating map according to the road section information; and sending the road section updating map to the unmanned vehicle. Therefore, the processing amount of the map data can be reduced, the drawing efficiency is improved, the map of the unmanned vehicle is updated in time, and normal driving of the unmanned vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device, system and storage medium for updating map data. Background technique [0002] With the development of automobile technology, unmanned vehicles have begun to be applied. When the unmanned vehicle is driving, it needs to perform automatic driving control according to the pre-stored map data. Therefore, in order to ensure the normal driving of the unmanned vehicle, it is necessary to update the map data in the unmanned vehicle in time. [0003] In the prior art, when updating map data, it is first necessary to obtain all the information for making the map; then, generate a new map according to all the obtained information, or update the map according to all the obtained information. [0004] However, this update method requires a large amount of information to be processed. When using all the information to generate a new map, the workload of drawing is also...
