Problems solved by technology

[0002] The map of the existing navigation terminal needs to be updated by the user in time, otherwise changes in road surface information (such as road construction and road closures, etc.) will cause errors or even errors in the user's driving
[0003] However, even if the user frequently updates the map, it is still unavoidable to avoid the influence of the information input error of the map provider, and there will still be navigation errors, especially on some expressways, where an error at an intersection will bring great inconvenience to the driving user
[0004] Although it is possible to send special road scanning vehicles to collect road condition information to update maps, the cost is high and the efficiency is low

Abstract

The invention discloses a method and device for updating an online map by using an unmanned vehicle. The method comprises one specific implementation method: a sensor mounted on the unmanned vehicle is used for scanning a road where the unmanned vehicle is located currently to acquire real-time road information; a map information acquisition request is sent to a backstage server of the online map, wherein the map information acquisition request includes position information of the unmanned vehicle; whether the real-time road information is consistent to map information returned by the backstage server is detected; in an inconsistent case, detected map distinguishing information is sent back. The implementation method can reduce the manual updating and maintaining workload required during map data change, and also greatly improves the efficiency of map data updating.

Description

technical field [0001] The present application relates to the field of map technology, in particular to the field of online map update technology, and in particular to a method and device for updating an online map by using an unmanned vehicle. Background technique [0002] The map of the existing navigation terminal needs to be updated by the user in time, otherwise changes in road surface information (such as road construction and road closures, etc.) will cause errors or even errors in the user's driving. [0003] However, even if the user frequently updates the map, it is still impossible to avoid the influence of the information input error of the map provider, and there will still be navigation errors, especially on some expressways, where an error at an intersection will bring great inconvenience to the driving user . [0004] Although it is possible to send special road scanning vehicles to collect road condition information to update maps, the cost is high and the ...
