Abstract

The invention relates to the technical field of terminals, in particular to a method and equipment for calibrating a compass, which aim at solving the problems of requirement of calibrating for multiple times, and low calibrating efficiency in the existing compass. The method comprises the following steps of enabling the terminal to calibrate the compass in the calibrating process according to theterminal track; if the calibrating fails, enabling the terminal to display the information for assisting the user to calibrate. The method has the advantages that after the calibrating by the user fails, the information for assisting the user to calibrate can be displayed to the user, so that the user can refer to the auxiliary information to calibrate in the next time of calibrating process; thecalibrating is more accurate, and the calibrating efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a compass calibration method and equipment. Background technique [0002] With the increasing dependence of end users on mobile terminals, the terminal compass has become an important module of software such as navigation software and positioning software. However, there is a relatively important problem in the development process of the compass, that is, after each restart of the mobile device, the compass needs to be calibrated before it can be used normally. [0003] The terminal compass is mainly affected by the geomagnetic field during use, and the test is inaccurate due to the difference in the material of the terminal shell outside the terminal compass. Before using the compass function, it is necessary to calibrate the compass. The solution for calibrating the compass in the mobile phone system in the prior art is: when the accuracy value of the compass deviate...
