Embodiment Construction

[0046] Below in conjunction with accompanying drawing, specifically describe the implementation process of the inventive method:

[0047] See figure 1 , the requested positioning user A is holding mobile smart device a, and the requested positioning user B is holding mobile smart device b. Both mobile smart device a and mobile smart device b have built-in wireless short-distance communication modules, direction sensors and three-axis acceleration sensors. Mobile smart devices a. Mobile smart devices b establish wireless communication links through their built-in wireless short-distance communication modules to transmit data. Mobile smart devices use direction sensors and three-axis acceleration sensors to record the user's movement distance and direction by counting steps. , which includes the following positioning steps:

[0048] (1) At any time T1, the user B who requests positioning sends a positioning request to the mobile smart device a held by the requested user A thro...

Abstract

The invention provides a method for positioning mobile intelligent devices within a short distance, and can solve the problem that the accurate positioning among mobile intelligent devices is performed by relying on external positioning devices such as GPS, Cell-ID, and Wifi currently. The method is characterized in that at least one user A requested to be positioned holds a mobile intelligent device a, at least one user B requesting for positioning holds a mobile intelligent device b, a wireless communication link is established between the mobile intelligent device a and the mobile intelligent device b through a built-in wireless short-distance communication module and can be used for carrying out data transmission, the two mobile intelligent devices respectively record moving distances and moving directions of the users in a step recording mode through a built-in direction sensor and a three-axis acceleration sensor, and according to received signal strength of the mobile intelligent device a at the moments T1, T2 and T3, the moving distances and direction vectors of the mobile intelligent devices a and b during the T1-T2 time period and the T2-T3 time period, the relative positions of the users A and B requested to be positioned are calculated at the moments T1, T2 and T3, and the relative positions are displayed on the mobile intelligent device b.

Description

technical field [0001] The invention relates to the technical field of mobile scenario calculation and human-computer interaction, in particular to a positioning method between mobile smart devices. Background technique [0002] In daily life, in some specific application scenarios, such as when a tour guide leads a tour group, or when parents bring children in public places, parents and tour guides need to obtain real-time information about the nearby tourists and children relative to themselves through their respective mobile devices. Similar application requirements also appear in application scenarios such as netizens meeting for the first time, express delivery and sending and receiving. [0003] The current mutual positioning method between devices mainly uses two devices to obtain their respective positions through GPS at the same time, and uploads their respective positions to a server, and the server calculates the relative positions between the devices; however, th...
