Embodiment 1

[0024] refer to figure 1 , which shows a flowchart of a calibration method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0025] Step 110, before the magnetic sensor of the mobile terminal or a sensor related to the magnetic sensor is turned on, it is judged whether a preset condition is met.

[0026] In the embodiment of the present invention, when a user uses a mobile terminal, many applications or devices themselves need to obtain the current location information of the mobile terminal, and the location data is obtained through magnetic sensors and related sensors, and the obtained data must be calibrated to be accurate. The user is provided with correct positioning information, so when it is detected that the magnetic sensor and related sensors are about to be turned on, it is further detected whether the current mobile terminal satisfies the preset condition.

[0027] Specifically, taking a mobile terminal installed with a...

Embodiment 2

[0032] refer to figure 2 , which shows a flowchart of a calibration method in Embodiment 2 of the present invention, which may specifically include the following steps:

[0033] Step 201, before the magnetic sensor of the mobile terminal or a sensor related to the magnetic sensor is turned on, it is judged whether a preset condition is satisfied.

[0034] This step is the same as step 110 and will not be described in detail here.

[0035] Step 202, acquiring first energy consumption information for calibrating the magnetic sensor of the mobile terminal.

[0036] In the embodiment of the present invention, taking a mobile terminal installed with an Android system as an example, the power consumption statistical data of each application can be obtained through its open power consumption interface, and the power usage summary of each application can be obtained by using the power statistics class PowerUsageSummary According to the relevant data of batteryinfo, it is further kn...

Abstract

The invention provides a calibration method and a mobile terminal. The method comprises the following steps of before a magnetic sensor of the mobile terminal or a sensor related to the magnetic sensor is turned on, judging whether a preset condition is met or not; if the preset condition is met, calibrating the magnetic sensor. The preset condition comprises at least one of the following items: the magnetic sensor is not calibrated; the magnetic sensor is not in a calibration state; the duration since the previous calibration time of the magnetic sensor exceeds a second preset time; and the mobile terminal is in a static state. The magnetic sensor is calibrated in advance, and the correct direction information can be provided for users just in time.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a calibration method and a mobile terminal. Background technique [0002] With the rapid development of mobile terminal positioning technology, most mobile terminals are equipped with magnetic sensors and related sensors responsible for positioning functions, which are mainly used to provide users with the correct direction. However, magnetic sensors and related sensors must provide correct Orientation must be calibrated, otherwise the orientation provided is incorrect. [0003] At present, the calibration process of the magnetic sensor and related sensors is generally started when the device needs to use the positioning function, that is, after the magnetic sensor and related sensors of the device are turned on, the magnetic calibration algorithm starts to run to calibrate the magnetic sensor. When the magnetic sensor and associated sensors are turned off, the ...
