Abstract

The invention provides a positioning data sampling period adjustment method and device and a mobile terminal. The positioning data sampling period adjustment method comprises obtaining at least three continuous samples of positioning data of the mobile terminal before the current moment; calculating the movement information of the mobile terminal according to the obtained positioning data; determining a sampling period of a next time of positioning data sample according to the movement information; collecting positioning data of the mobile terminal according to the determined sampling period. According to the positioning data sampling period adjustment method and device and the mobile terminal, the problem that the data collection error or the data loss is easy to produce under the condition that the movement change of the mobile terminal is large due to the fact that positioning data are collected according to a preset period in the prior art is solved and accordingly the movement curve of the mobile terminal can be scientifically reflected by the positioning data which are obtained through sampling and the recording on the movement curve of the mobile terminal or the monitoring on the mobile terminal by a user can be effective.

Description

technical field [0001] The invention relates to the field of mobile positioning, in particular to a method, a device and a mobile terminal for adjusting the sampling period of positioning data. Background technique [0002] With the development of mobile terminals and navigation technologies, using a mobile terminal to navigate or to record or monitor a motion track of the mobile terminal is an application frequently used by users. In the prior art, when the mobile terminal is in an outdoor environment, the mobile terminal collects GPS positioning data according to a preset cycle, and then according to the collected GPS (Global Positioning System) positioning data and GIS (Geographic Information System geographic information system) information Obtain the movement trajectory of the mobile terminal or the movement route of the target location, etc. However, there is a relatively big defect in using this method to record the movement trajectory of the mobile terminal. The mob...
