Embodiment 1

[0068] see figure 1 , figure 1 It is a schematic flowchart of a real-time positioning method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the real-time positioning method may include the following steps:

[0069] 101. The electronic device acquires starting point positioning information of an initial positioning period.

[0070] 102. When the initial positioning period ends, the electronic device acquires end point positioning information of the initial positioning period. Wherein, the initial positioning period refers to the first positioning period in which the electronic device starts to perform real-time positioning. Specifically, the positioning period may be 3 seconds. Certainly, besides 3 seconds, the positioning period may be other values, for example, 2.6 seconds or 3.8 seconds, etc., and the embodiment of the present invention does not specifically limit the positioning period.

[0071] When positioning an electronic device, t...

Embodiment 2

[0086] see figure 2 , figure 2 It is a schematic flowchart of another real-time positioning method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the real-time positioning method may include the following steps:

[0087] 201-204. For the description of steps 201 to 204, please refer to the detailed description of steps 101 to 104 in Embodiment 1, and the present invention will not repeat them here.

[0088] 205. The electronic device acquires the actual moving speed of the initial positioning period.

[0089] As an optional implementation manner, after performing step 205, the following steps may also be performed:

[0090]The electronic device detects whether it is in the electronic map navigation mode; if it is in the electronic map navigation mode, the electronic device judges whether the actual moving speed reaches the preset speed threshold; if the preset speed threshold is reached, and the electronic identification corresponding ...

Embodiment 3

[0102] see image 3 , image 3 It is a schematic flowchart of another real-time positioning method disclosed in the embodiment of the present invention. Such as image 3 As shown, the real-time positioning method may include the following steps:

[0103] 301. The wearable device determines the duration of the initial positioning period, the update time interval, and a positive integer N according to the preset minimum period, the preset maximum waiting value, and the target preset maximum period corresponding to the current movement scene of the wearable device.

[0104] Among them, the preset minimum period is obtained according to the power consumption limit parameter of the wearable device, the preset maximum waiting value is obtained according to the feedback information of multiple users for positioning delay, and the duration of the initial positioning period is not less than the preset minimum period, And the duration of the initial positioning period is not greater ...

Abstract

The embodiment of the present invention relates to the technical field of positioning, and discloses a real-time positioning method and a wearable device. The method includes: obtaining the starting point positioning information of the initial positioning cycle; at the end of the initial positioning cycle, obtaining the end point positioning information of the initial positioning cycle; obtaining a virtual positioning track according to the starting point positioning information and the end point positioning information; dividing the virtual positioning track into N segments , to obtain N‑1 virtual positioning information, N is a positive integer greater than 1; the 1 / N duration of the initial positioning cycle is used as the update time interval; according to the update time interval, N+1 times in the next positioning cycle are gradually based on the starting point positioning information , N-1 pieces of virtual positioning information and terminal positioning information for positioning update. By implementing the embodiments of the present invention, periodic positioning can be performed at relatively large time intervals, and intra-period positioning updates can be performed at relatively small time intervals, which can reduce device power consumption and thereby improve battery life.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a real-time positioning method and a wearable device. Background technique [0002] At present, precise positioning is one of the core functions of wearable devices such as smart glasses, smart watches and smart bracelets, especially for smart watches usually worn by child users. It can send positioning information to the mobile terminal used by the parents, and can feedback the precise changes of the child's location information to the parents, assisting the parents to pay attention to which direction the child is going or to judge whether the child deviates from the predetermined route. [0003] In practical applications, in order to provide real-time feedback of precise changes in the child's location information, periodic positioning is generally performed at relatively small time intervals. However, it has been found in practice that in the method of performing periodi...
