Embodiment 1
[0082] Such as figure 1 As shown, in a specific embodiment, the present invention provides a method for obtaining a relative distance based on Wi-Fi, which includes:
[0083] The first terminal sends a distance acquisition request to the second terminal; the first terminal collects terminal information of the first terminal;
[0084] After obtaining the distance obtaining request, the second terminal collects terminal information of the second terminal, and sends the terminal information to the first terminal;
[0085] After the first terminal receives the terminal information sent by the second terminal, it matches it with the terminal information of the first terminal, and calculates the relative relationship between the first terminal and the second terminal according to the matching result. distance;
[0086] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station information collected by the terminal, and time information. Th...
Embodiment 2
[0109] Such as figure 2 As shown, the present invention also provides a terminal that can obtain a relative distance, and the terminal includes:
[0110] The request receiving unit is used to send and / or receive a distance acquisition request;
[0111] A terminal information acquisition unit, configured to acquire terminal information collected by the terminal itself, and receive collected terminal information sent by other terminals;
[0112] The distance acquiring unit is configured to match the terminal information sent by the other terminal by the terminal with the terminal information collected by the terminal itself, and calculate the relationship between the terminal and the other terminal according to the matching result. The relative distance of the terminal;
[0113] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station information collected by the terminal, and time information.
[0114] In a specific implementation, th...
Embodiment 3
[0123] In yet another specific implementation manner, the present invention also provides another method for acquiring the relative distance of a terminal, which includes:
[0124] The first terminal sends a distance acquisition request to the second terminal;
[0125] Collecting terminal information of the first terminal by the first terminal;
[0126] After obtaining the distance obtaining request, the second terminal collects terminal information of the second terminal, and sends the terminal information to the first terminal;
[0127] After receiving the terminal information sent by the second terminal, the first terminal extracts the feature vectors of the terminal information of the first terminal and the second terminal, and obtains the first terminal and the first terminal through a distance calculation function. The relative distance of the two terminals;
[0128] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station infor...
