In this example, the preset calibration control strategy includes: when the absolute value of the difference between the first angle value and the second angle value is smaller than a preset first angle difference threshold value, updating the second angle value into the first angle value;

or directly updating the second angle value to the first angle value;

or when a second compass module of the wearable device is currently in a first precision mode, when an absolute value of a difference between the first angle value and the second angle value is smaller than a preset second angle difference threshold, updating the second angle value to the first angle value; otherwise, the second angle value is not updated;

or when a second compass module of the wearable device is currently in a first precision mode, when an absolute value of a difference between the first angle value and the second angle value is smaller than a preset second angle difference threshold, updating the second angle value to the first angle value; otherwise, the second angle value is not updated; and when the second compass module is currently in a fourth precision mode, directly updating the second angle value to the first angle value.

The first calibration control strategy and the second calibration control strategy are described below with reference to the embodiments. For example, the first angle is 100 °, the second angle is 80 °, and the second calibration control strategy is to directly update the 80 ° of the second angle to 100 ° of the first angle. A first calibration control strategy is to set a preset first angle difference threshold value to 30 deg. in addition to a first angle value of 100 deg., a second angle value of 80 deg.. The absolute value of the difference between the first angle value and the second angle value is now 20 deg., 20 deg. being smaller than 30 deg., and 80 deg. of the second angle is updated to 100 deg. of the first angle. The angles are only used to better illustrate the calibration control strategy, the embodiment is not limited to these degrees, and the preset first angle threshold may be set by the user or factory.

The third calibration control strategy is further described below. When a second compass module of the wearable device is currently in a first precision mode, when the absolute value of the difference between a first angle value and a second angle value is smaller than a preset second angle difference threshold value, updating the second angle value to the first angle value; otherwise, the second angle value is not updated. The first precision mode is as follows: the precision value is detected through a sensor bottom layer driving circuit, the feedback precision mode is a first precision mode or the second pointer of the second pointer module is the same as the first pointer of the first compass module in pointing direction, and the absolute value of the difference between the second angle value of the second pointer module and the first angle value of the first compass module is smaller than or equal to a first correction angle difference threshold value. The method can also comprise the following steps:

when a second compass module is currently in a second precision mode, when the absolute value of the difference between the first angle value and a second angle value is smaller than a preset third angle difference threshold value, updating the second angle value to the first angle value; otherwise, not updating the second angle value; wherein the second accuracy mode is: the precision value is detected through a sensor bottom layer driving circuit, the feedback precision mode is a second precision mode or the second pointer of the second pointer module is the same as the first pointer of the first compass module in pointing direction, and the absolute value of the difference between the second angle value of the second pointer module and the first angle value of the first compass module is larger than a first correction angle difference threshold value and smaller than or equal to a second correction angle difference threshold value.

When the second compass module is currently in a third precision mode, directly updating the second angle value into the first angle value; the third accuracy mode is: the precision value is detected through a sensor bottom layer driving circuit, the feedback precision mode is a third precision mode or the second pointer of the second pointer module is the same as the first pointer of the first compass module in pointing direction, and the absolute value of the difference between the second angle value of the second pointer module and the first angle value of the first compass module is larger than a second correction angle difference threshold value and smaller than or equal to a third correction angle difference threshold value.

When the second compass module is currently in a fourth precision mode, directly updating the second angle value to the first angle value; the fourth accuracy mode is: the second compass module cannot currently acquire an effective second angle value.

For example, the first correction angle threshold is 5 degrees, the second correction angle threshold is 30 degrees, and the third correction angle threshold is 100 degrees. It is understood that the accuracy of the first accuracy mode is higher than that of the second accuracy mode, and the accuracy of the second accuracy mode is higher than that of the third accuracy mode. Taking the example that the second pointer module of the wearable device is in the first precision mode: the preset second angle difference threshold is 8 degrees, the absolute value of the difference between the first angle value and the second angle value is 5 degrees, and the second angle value is updated to be the first angle value when the 5 degrees are smaller than 8 degrees. If the absolute value of the difference between the first angle value and the second angle value is 30 deg., 30 deg. is greater than 8 deg., the second angle value is not updated. If the second compass module of the wearable device is in the second accuracy mode, the preset third angle difference threshold value is 40 degrees, the absolute value of the difference between the first angle value and the second angle value is less than 40 degrees, the first angle value is updated to the second angle value, and otherwise, the first angle value is not updated. The angles are only used to better describe the calibration control strategy, and the present embodiment is not limited to these degrees, and the first calibration angle threshold, the second calibration angle threshold, the third calibration angle threshold, the preset second angle threshold, and the preset third angle difference threshold may be set by the user or factory settings.

The fourth calibration control strategy is further described below. The fourth calibration control strategy may further include at least one of:

when a second compass module is currently in a second precision mode, when the absolute value of the difference between the first angle value and a second angle value is smaller than a preset third angle difference threshold value, updating the second angle value to the first angle value; otherwise, not updating the second angle value; wherein the second accuracy mode is: when the second pointer of the second pointer module points the same as the first pointer of the first compass module, the absolute value of the difference between the second angle value of the second pointer module and the first angle value of the first compass module is greater than the first correction angle difference threshold and less than or equal to the second correction angle difference threshold.

When the second compass module is currently in a third precision mode, directly updating the second angle value into the first angle value; the third accuracy mode is: when the second pointer of the second pointer module points the same as the first pointer of the first compass module, the absolute value of the difference between the second angle value of the second pointer module and the first angle value of the first compass module is greater than the second correction angle difference threshold and less than or equal to the third correction angle difference threshold.
