The embodiment of the present application discloses a method for calibrating magnetometer data, which is applied to a terminal device with a folding screen and a magnetometer. The method includes: acquiring the bending angle of the folding screen and the magnetometer data of the magnetometer; The first angle interval where the bending angle is located; the target soft magnetic parameter is determined from the preset soft magnetic parameter set according to the first angle interval; the magnetometer data is calibrated according to the target soft magnetic parameter to obtain first calibration data. The embodiment of the present application also provides a corresponding magnetometer data calibration device. The technical solution of the present application can determine the corresponding target soft magnetic parameters according to different bending angles of the folding screen to calibrate the magnetometer data, which can solve the problem caused by the change of soft magnetic interference during the folding process of the folding screen, and provides a folding screen The solution of how to calibrate the magnetometer data of the screen terminal equipment under different bending states.
Description
technical field [0001] The present application relates to the technical field of magnetometers, in particular to a method for calibrating magnetometer data and a device for calibrating magnetometer data. Background technique [0002] With the development of the times, electronic devices such as mobile phones have become indispensable items in people's lives. With the development and progress of science and technology, the functions of electronic devices such as mobile phones have become more diverse. Today's smart phones basically have applications such as navigation and compass. [0003] Applications such as navigation and compass in mobile phones and other electronic devices need to use magnetometer data when they are used, but magnetometer data is susceptible to interference, which mainly includes soft magnetic interference. Soft magnetic interference mainly comes from some soft magnetic materials that are easily magnetized in electronic equipment. Soft magnetic interfer...
