Pattern recognition system for sensor calibration in autonomous vehicles

A computer-implemented method for sensor calibration in an autonomous vehicle, the computer-implemented method comprising:

• retrieving reference data indicating at least one baseline parameter;
• receiving sensor data from at least one sensor of the autonomous vehicle during operation of the autonomous vehicle, the sensor data indicating at least one measured parameter;
• identifying at least one calibration error of the at least one sensor by comparing the at least one measured parameter to the at least one baseline parameter;
• generating a record in a memory including the at least one calibration error;
• controlling operation of the autonomous vehicle based on the at least one calibration error;
• generating, based on the record and at least one other historical record, a consistency profile identifying at least one pattern resulting in the at least one calibration error;
• and
• adjusting at least one parameter of the at least one sensor based on the consistency profile.

An autonomous vehicle comprising:

• at least one sensor;
• and
• an autonomy computing system comprising a processor and a memory in communication with the processor, the processor programmed to:
• retrieve reference data indicating at least one baseline parameter;
• receive sensor data from the at least one sensor of the autonomous vehicle during operation of the autonomous vehicle, the sensor data indicating at least one measured parameter;
• identify at least one calibration error of the at least one sensor by comparing the at least one measured parameter to the at least one baseline parameter;
• generate a record in the memory including the at least one calibration error;
• control operation of the autonomous vehicle based on the at least one calibration error;
• generate, based on the record and at least one other historical record, a consistency profile identifying at least one pattern resulting in the at least one calibration error;
• and
• adjust at least one parameter of the at least one sensor based on the consistency profile.
