Abstract

The embodiment of the present invention discloses a method for automatically calibrating a geomagnetic sensor and a smart watch, which are applied to the technical field of terminals and can solve the problem of difficult operation of calibrating the geomagnetic sensor. The smart watch includes a watch strap and a watch body connected to the watch band. The watch body includes a flip part and a fixed part. The flip part can be rotatably connected to the fixed part. The flip part is provided with a geomagnetic sensor. The fixed part forms a preset angle, and controls the flip part to rotate by the preset angle. During the process of controlling the flip part to rotate the preset angle, the geomagnetic parameters detected by the smart watch are acquired; the geomagnetic sensor is calibrated according to the acquired geomagnetic parameters.

Description

Technical field [0001] Embodiments of the present invention relates to the field of terminal technology, in particular to a method of automatically calibrating a geomagnetic sensor and a smart watch. Background [0002] With the development of electronic technology, many smart watches have global positioning system function and compass function, in order to achieve smart watches these functions need to accurately calculate the direction of movement of smart watches, geomagnetic sensors are widely used in calculating the direction of movement of smart watches. For example, a geomagnetic sensor is mounted on a smartwatch and calculates the direction of movement of the smartwatch's smartwatch. However, the geomagnetic sensor in the actual use of the process will be affected by the surrounding magnetic field, resulting in a large error, usually the prior art can be made smart watch "around the 8 characters" (that is, the smart watch rotates in different directions) to ensure that the...
