Example Embodiment
[0042] Example one
[0043] Please refer to figure 1 , The method for acquiring location information of a mobile terminal in this embodiment includes:
[0044] Step 101: Turn on the satellite positioning module of the mobile terminal, obtain the current position information of the mobile terminal and turn it off, and use the current position information as the initial position information;
[0045] Step 102: The sensing module of the mobile terminal collects the movement information of the mobile terminal, and calculates the displacement change of the mobile terminal according to the movement information;
[0046] Step 103: Obtain actual position information of the mobile terminal according to the initial position information and the displacement change amount of the mobile terminal.
[0047] The method of this embodiment may further include: periodically turning on the satellite positioning module of the mobile terminal to obtain the current position information of the mobile terminal,...
Example Embodiment
[0078] Example two
[0079] Based on the method for acquiring location information of a mobile terminal in the first embodiment, this implementation takes a mobile phone with a GPS or AGPS module as an example. The basic idea is: take the device position read by the GPS (AGPS) module as the origin, use the acceleration sensor and the electronic compass to measure the device acceleration, calculate the device displacement increment, thereby calculate the actual position of the device at the corresponding time, and update the device position in time Information; the GPS (AGPS) module reads the position information again, updates the initial position of the device (that is, the origin of the last displacement), sets the displacement increment to 0, recalculates the displacement increment, and repeats this cycle; GPS ( The specific time threshold or displacement threshold of the position information read by the AGPS module makes the reading frequency lower, such as reading once every...
