METHOD, DEVICE, AND SYSTEM FOR PROCESSING MAP UPDATE DATA

This application provides a map update data processing method, apparatus, and system, and relates to the field of autonomous driving technologies. The method includes: obtaining first information from at least one vehicle terminal in a time window, where the vehicle terminal may be a smart vehicle, and the first information does not match corresponding second information in a local map stored in the vehicle terminal; determining, based on the first information, first change information of the second information and precision information and/or confidence information corresponding to the first change information, where the first change information is information about a difference between the first information and the second information; and finally, sending the first change information of the second information and the precision information and/or the confidence information corresponding to the first change information to the at least one vehicle terminal, where the precision information and/or the confidence information corresponding to the first change information is used by the vehicle terminal to determine whether to use the first change information of the second information. The solution provided in this application may be used to improve reliability of crowdsourced map update data.
