Abstract
A system and method for system learning updates for online sensor alignment includes receiving sensor data detected by a sensor system of a vehicle, generating, using a coordinate transformation matrix (CTM), a sensor alignment result, and determining, based on a degradation detection model, that a deviation between the sensor alignment result and one or more of a fleet model, a vehicle model, and a system model exceeds an onboard degradation threshold. The system and method also includes determining, based on an offline degradation model, that a deviation between the sensor alignment result and an offline model result exceeds an offline degradation threshold, and triggering corner case data collection to collect additional sensor data detected by the sensor system of the vehicle.
