Abstract
The method for autonomous vehicle control preferably includes sampling measurements, determining refined sensor poses based on the measurements, determining an updated vehicle pose based on the measurements and operation matrix, optionally determining evaluation sensor poses based on the refined sensor poses, optionally updating the operation matrix(es) based on the evaluation sensor poses, and/or any other suitable elements. The system for autonomous vehicle control can include one or more vehicles, one or more sensors, one or more processing systems, and/or any other suitable components.
Claims20
A system for a vehicle comprising:
- a vehicle sensor suite;
- and
- a processor configured to, during operation of the vehicle, iteratively:
- calculate sensor poses for each of a plurality of sensors of the vehicle sensor suite based on an operation calibration for the vehicle sensor suite and sensor measurements from the plurality of sensors;
- calculate an evaluation calibration based on the sensor poses, wherein the evaluation calibration represents an updated version of the operation calibration;
- and
- update the operation calibration based on the evaluation calibration being within a threshold difference of a previous evaluation calibration,
- wherein the processor is further configured to flag the vehicle when the evaluation calibration and the previous evaluation calibration satisfy a convergence-failure condition.
A method for a vehicle, comprising:
- during operation of the vehicle, repeatedly:
- generating sensor measurements with a plurality of vehicle sensors;
- based on an operation calibration for the plurality of vehicle sensors and the sensor measurements, determining sensor poses for each of the plurality of sensors;
- calculating an evaluation calibration based on the sensor poses;
- and
- selectively updating the operation calibration when the evaluation calibration is within a threshold difference of a previous evaluation calibration;
- and
- flagging the vehicle when the evaluation calibration and the previous evaluation calibration satisfy a convergence-failure condition.
