CLOUD BASED SCANNING FOR DETECTION OF SENSORS MALFUNCTION FOR AUTONOMOUS VEHICLES

In one embodiment, a system obtains first point cloud data generated by a first scanner device of a first autonomous driving vehicle (ADV). The system applies one or more abnormality detection algorithms to the first point cloud data to determine an abnormality in the first point cloud data. The system determines an abnormality type for the abnormality. The system determines the abnormality is above a severity threshold based on the abnormality type. In response to determining that the abnormality is above the severity threshold, the system indicates a warning to inspect the first scanner device for any hardware malfunctions.
