Calibration method and device of geomagnetic sensor, electronic equipment and storage medium

The invention relates to a calibration method and device of a geomagnetic sensor, electronic equipment and a storage medium, and belongs to the technical field of geomagnetic sensors. The method comprises the following steps: obtaining a first sampling coordinate point, a second sampling coordinate point, a third sampling coordinate point and a fourth sampling coordinate point, constructing a sphere, and obtaining a target sphere center coordinate and a target radius of a target sphere; wherein the distance between every two sampling coordinate points is larger than square root of two times of the target radius, and the distance between every two sampling coordinate points is smaller than two times of the target radius; and obtaining a judgment calibration result based on the target radius and a preset threshold value. The calibration of the geomagnetic sensor is completed by acquiring the four sampling coordinate points meeting the conditions and calculating the target sphere center coordinate and the target
