Document Type and Number:
WIPO Patent Application WO/2023/169422
Kind Code:
A1
Abstract:
An electronic compass calibration method and apparatus, an electronic device (90, 100), and a storage medium, which relate to the technical field of communications. The electronic device (90, 100) comprises: a target key (12), at least one Hall sensor (13, 14), and an electronic compass (15). The calibration method comprises: acquiring target position information of the target key (12) by means of the at least one Hall sensor (13, 14), wherein the target position information is used for indicating the key position of the target key (12) on the electronic device (90, 100); determining a target calibration parameter by means of the electronic compass (15) according to the target position information; and calibrating a magnetic field parameter output by the electronic compass (15) by using the target calibration parameter.
