Application: System and method for fast magnetometer calibration using gyroscope (Patent ID: US20240045001A1)
The patent filed by STMicroelectronics NV describes an electronic device equipped with a magnetometer and gyroscope for generating sensor signals. The device includes a magnetometer calibration module that utilizes the gyroscope sensor signals to calibrate the magnetometer. The calibration process involves generating two calibration parameters using different analysis processes, such as a Kalman filter and least squares estimation. These parameters are validated by analyzing their convergence, and the magnetometer is continuously calibrated by running multiple instances of the calibration processes simultaneously, with time offsets.
The method and electronic device outlined in the patent focus on accurately calibrating a magnetometer by leveraging gyroscope sensor signals. The calibration involves estimating two calibration parameters through distinct analysis processes, validating their accuracy through convergence analysis, and continuously calibrating the magnetometer by running multiple instances of the calibration processes simultaneously with time offsets. This innovative approach ensures precise calibration of the magnetometer, which is crucial for determining the orientation and heading of the electronic device, particularly in applications like virtual reality or augmented reality headsets.
