Abstract

The embodiment of the invention discloses a method for automatically calibrating a geomagnetic sensor and a smart watch, is applied to the technical field of terminals, and can solve the problem of high operation difficulty in calibrating the geomagnetic sensor. The smart watch comprises a watchband and a watch body connected with the watchband. The watch body comprises an overturning part and a fixed part. The overturning part is rotatably connected with the fixed part, a geomagnetic sensor is arranged in the overturning part, the smart watch can control the overturning part to turn over to form a preset included angle with the fixed part and control the overturning part to rotate by a preset angle. In the process of controlling the overturning part to rotate by the preset angle, the geomagnetic parameters detected by the smart watch are obtained; and the geomagnetic sensor is calibrated according to the acquired geomagnetic parameters.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminals, in particular to a method for automatically calibrating a geomagnetic sensor and a smart watch. Background technique [0002] With the development of electronic technology, many smart watches have GPS function and compass function. In order to realize these functions of smart watches, it is necessary to accurately calculate the moving direction of smart watches. Geomagnetic sensors are widely used to calculate the moving direction of smart watches. For example, a geomagnetic sensor is installed on a smart watch and calculates the moving direction of the smart watch from the smart watch. However, the geomagnetic sensor will be affected by the surrounding magnetic field during actual use, resulting in a large error. Generally, in the prior art, the smart watch can be guaranteed to be smart by making the smart watch "circle the figure of eight" (that is, the smart watch rotat...
