摘要： The present disclosure provides methods and systems of maintaining a map suitable for guiding autonomous driving. In some embodiments, the method may include receiving a sensor dataset acquired by a sensor subsystem, wherein: the sensor dataset includes information about a road, the sensor subsystem comprises multiple different types of sensors; determining, by a processor, a confidence level by comparing the sensor dataset and the map that includes prior information about the road; in response to determining that the confidence level exceeds a confidence threshold, processing the map by the processor; and storing the processed map as an electronic file, wherein the processed map is configured to guide an autonomous vehicle to operate on the road.
