Real-time localization error correction of autonomous vehicle

An autonomous vehicle (AV), comprising a processor for real-time localization error correction of the AV, and one or more image capture devices, wherein

• the processor is configured to:
• retrieve a reference landmark around the AV from a map aggregating server (MAS), wherein the AV is configured to interact with the MAS for real-time localization;
• detect, in real time, a ground truth landmark corresponding to the reference landmark, according to image data captured by the one or more image capture devices;
• calculate a deviation between the ground truth landmark and the reference landmark as a real-time correction value for the real-time localization of the AV;
• retrieve, from the MAS, a reference correction value associated with a road segment where the AV is travelling;
• calculate an average value of the reference correction value and the real-time correction value as a final real-time correction value for the real-time localization;
• perform the real-time localization error correction of the AV based on the final real-time correction value;
• and
• cause the AV to autonomously drive to a destination based on the real-time localization of the AV after the real-time localization error correction.
