1. A method of updating a cloud-based road anomaly database, comprising:
receiving information from a vehicle regarding a first object and a second object detected by one or more sensors of the vehicle, the information comprising at least one of a location or a size of the detected object;
comparing at least one of the location or the size of the first detected object against data stored in a road feature database regarding the first detected object;
determining, based on comparing the at least one of the location or the size, an accuracy score associated with the second detected object; and
updating the cloud-based road anomaly database with the received information for the second detected object based on the associated accuracy score being higher than at least one of a threshold accuracy score or an accuracy score associated with corresponding object information stored in the cloud-based road anomaly database.
