  • Distortion Correction for Electromagnetic Fields Using Inside-Out Tracking
    Publication number: 20210386485
    Abstract: A magnetic tracking device is configured to track an object in an environment by receiving a measurement of the non-magnetic signal and a corresponding measurement of the magnetic signal for a location of the magnetic tracking device in the environment. The magnetic tracking device estimates, based on the measurement of the non-magnetic signal, a non-magnetic pose of the magnetic tracking device in the environment for the location. The device estimates, based on the measurement of the magnetic signal, a magnetic pose of the magnetic tracking device in the environment for the location. The device determines a difference between the magnetic pose estimate and the non-magnetic pose estimate for the location. The device determines a magnetic distortion correction value for the location based on the difference. The magnetic tracking device generates a distortion correction model including the distortion value and outputs a representation of the distortion correction model.
