The present disclosure is directed to checking and updating the calibration of a sensing apparatus at an autonomous vehicle (AV). After a sensing apparatus of an AV has been initially calibrated (e.g., when the AV is manufactured) calibration of that sensing apparatus may be checked or updated using data collected from similar vehicles of a fleet of vehicles. Each of the different vehicles of this fleet may identity its location and report that location. A first of these vehicles may receive data that identifies the location of a second vehicle. A sensing apparatus of the first vehicle may then identify locations of features at the second vehicle and a processor of the sensing apparatus may perform calculations to identify whether calibration of the sensing apparatus has changed. Parameters that adjust the calibration of the sensing apparatus may then be updated to maintain calibration of a sensing apparatus within acceptable tolerances.
