[0004] However, when using the existing technology for relative positioning, special sounds, such as the sound of thunder, are needed for accurate positioning, and the sound will be affected by the angle. For example, in the same environment, the microphone of one device is facing the sound source, and the other If the microphone of the device is facing away from the sound source, the intensity of the collected sound will be different
Therefore, in summary, when using the existing technology for relative positioning, it is greatly affected by the environment and the positioning is inaccurate

Embodiment 1
[0024] The embodiment of the present invention provides a relative positioning method, such as figure 1 As shown, the method includes:
[0025] Step 101, determining a first positioning range;
[0027] Step 102, within the first positioning range, determine a second positioning range where the terminal to be connected is located according to the measured environmental sensing parameters;
[0053] Step 302, the terminal measures environmental sensing parameters;
[0054] The sensor is installed on the terminal, and the environmental sensing parameters can be measured through the sensor. Optionally, the sensor can be an altimeter, a barometric sensor, a temperature sensor, a humidity sensor, etc. The altimeter can measure...

Abstract
The invention discloses a relative positioning method and device, and relates to an electronic technology field. The relative method and device can reduce environment influence, and is used for accuracy positioning. In a scheme provided in an embodiment of the invention, by determining a first positioning range and in the first positioning range, and a second positioning range of terminals to be connected based on sensor parameters of a measuring environment, and any first terminal to be connected in the terminals to be connected in the second positioning range is automatic connected, and shares information with the first terminals to be connected. The scheme provided in the embodiment of the invention is suitable for application when relative positioning.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a relative positioning method and device. Background technique [0002] Relative positioning is a positioning method to determine the relative position of the two parties to be positioned. The combination of relative positioning technology between devices and social networks can provide users with information more intelligently, and it can facilitate people to quickly share information in a specific place. [0003] The existing technology performs relative positioning through sound intensity. For example, when using sound positioning, the terminal collects the sound of the environment where the terminal is located through a microphone, and then uploads it to the server. The server receives and compares the sound collected by at least one terminal. When the sound intensity is the same , it means that the two terminals that collect the sound are in the same environment, so tha...
