A system includes a receiver mounted on a work machine, and a processor. The receiver receives a signal usable to identify a position of the work machine. The processor acquires a position of the receiver from the signal received by the receiver. The processor acquires a calculated position of a calibration point in the work machine by calculating a position of the calibration point from the position of the receiver. The processor acquires an actual position of the calibration point. The processor generates calibration data usable to calibrate a position of a reference point in the work machine by comparing the actual position with the calculated position of the calibration point.

Online machine learning for calibration of autonomous earth moving vehicles

In some implementations, the EMV uses a calibration to inform autonomous control over the EMV. To calibrate an EMV, the system first selects a calibration action comprising a control signal for actuating a control surface of the EMV. Then, using a calibration model comprising a machine learning model trained based on one or more previous calibration actions taken by the EMV, the system predicts a response of the control surface to the control signal of the calibration action. After the EMV executes the control signal to perform the calibration action, the EMV system monitors the actual response of the control signal and uses that to update the calibration model based on a comparison between the predicted and monitored states of the control surface.
