Virtual Anchor Point-based Wireless Positioning Method and Device, and Terminal

摘要

Provided are a virtual anchor point-based wireless positioning method and device, and terminal. The method includes: when an effective positioning condition is met, positioning data is acquired and stored, multipath analysis and tracking is simultaneously performed on received wireless signals transmitted by a signal transmission station, propagation distance information of each path of the signal transmission station is calculated and stored, and virtual image position information of each path of the signal transmission station is calculated and stored according to the positioning data and the propagation distance information of each path of the signal transmission station; and when the condition is not met, at least one virtual image is selected from virtual images of multiple paths of the signal transmission station as at least one positioning virtual anchor point, and current position information is obtained according to the effective positioning condition and the at least one positioning virtual anchor point.
