Positioned location adjustment method and apparatus

A visual positioning adjustment method, comprising:

• receiving, by a reference vehicle, a first request message from a first vehicle, wherein the first request message comprises first positioned location information of the first vehicle;
• when detecting that a positioning error value of the reference vehicle is less than a first threshold, extracting, by the reference vehicle, positioned location information of the reference vehicle and vehicle identifier information of the reference vehicle;
• and
• sending, by the reference vehicle, a first response message to the first vehicle, wherein the first response message comprises vehicle information of the reference vehicle, and the vehicle information of the reference vehicle comprises the positioned location information of the reference vehicle, the positioning error value of the reference vehicle, and the vehicle identifier information of the reference vehicle.

A positioned location adjustment apparatus, comprising:

• a transceiver configured to communicate with an apparatus other than the positioned location adjustment apparatus;
• a memory configured to store a computer executable instruction;
• and
• one or more processors connected to the memory and the transceiver through a bus, wherein when the computer executable instruction stored in the memory is executed by the processors cause the positioned location adjustment apparatus to be configured to perform the following method:
• sending a first request message to a plurality of reference vehicles, wherein the first request message is used to request vehicle information of the reference vehicle, the first request message comprises first positioned location information, and the first positioned location information is current location information of the positioned location adjustment apparatus;
• receiving a first response message from the reference vehicle, wherein the first response message comprises the vehicle information of the reference vehicle, and the vehicle information of the reference vehicle comprises positioned location information of the reference vehicle, a positioning error value of the reference vehicle, and vehicle identifier information of the reference vehicle;
• determining a second vehicle from the plurality of reference vehicles based on the positioning error value of the reference vehicle;
• and
• adjusting, the first positioned location information based on positioned location information of the second vehicle and vehicle identifier information of the second vehicle, to obtain second positioned location information.
