Lane information anomaly detection method, system and equipment for high-precision map

The invention discloses a lane information anomaly detection method, system and device for a high-precision map. The lane information anomaly detection method for the high-precision map comprises the following steps: extracting lane and lane line information of the high-precision map and lane and lane line information of perception detection; carrying out abnormity check and processing on the sensed and detected lane and lane line information; matching the lane meeting the matching requirement with the lane of the high-precision map according to the lane line information of the high-precision map and the lane line information meeting the matching requirement; and carrying out abnormity identification on the matched lanes of the high-precision map, and marking the abnormity of the lanes of the high-precision map. By adopting the method and the device, whether the lane level information in the high-precision map is abnormal or not can be detected in real time, the recorded abnormal information can be used for a
