data for magnetic field calbration
The EKF-based dynamic magnetic field calibration algorithm uses gyroscope data to calibrate magnetic field data. The magnetic field data can be well calibrated to the surface of the magnetic field sphere, which is superior to the traditional ellipsoid fitting algorithm.
These data were prepared to validate the EKF dynamic magnetic field calibration algorithm, which was acquired in some of the daily activities of the smartphone.
The phone is OPPO R9m
