Abstract

The invention relates to the field of positioning, and discloses a positioning method and device of a mobile terminal. The positioning method of the mobile terminal comprises the steps of obtaining a scanning fingerprint of a wireless signal at the position where the mobile terminal is; matching a fingerprint database based on the scanning fingerprint to obtain N anchor points with the highest matching score; generating a particle group based on the N anchor points; performing particle filtration on the particle group based on inertial navigation information to obtain alternative particle groups; determining the current movement model of the mobile terminal and performing particle scoring on the alternative particle groups based on the characteristics of the movement model; and obtaining a positioning solution of the mobile terminal based on the particle scoring result. The drifting and jumping probability of the positioned position can be reduced, the positioning track is enabled to be continuous, and the position positioning is accurate.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a positioning technology for a mobile terminal. Background technique [0002] During indoor and outdoor activities where satellite signals are weak or missing, such as roads, streets, parking lots, and airports, users need to know their precise location, and also want to know the trajectory planning from the current location to the destination location. [0003] In the existing technical solutions, positioning is simply based on WIFI or Bluetooth fingerprint information, which relies heavily on the collected signals in the fingerprint database and the quality of different hardware device sensors (such as mobile phones), and the algorithm is simple and the anti-interference ability is poor, so There will be problems such as inaccurate positioning positions, drifting or jumping positioning points, and discontinuous positioning tracks, which will affect user perception.
