Abstract

The invention provides indoor positioning method and device. The method comprises the steps of acquiring signal strength of a plurality of signal emitters in an indoor space and threshold strength of an emitting signal of each signal emitter; respectively determining the space distance value of each signal emitter according to each signal strength and threshold strength; selecting a plurality of signal emitters with relatively small space distance value from the plurality of signal emitters as the target signal emitters, so as to obtain a signal linear distribution matrix of each target signal emitter; generating a position probability matrix of each target signal emitter according to each signal linear distribution matrix and each signal strength; performing weighted stacking for the plurality of position probability matrixes to obtain a target position probability matrix; determining a second-dimensional coordinate value according to the target position probability matrix, so as to achieve indoor positioning.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an indoor positioning method and device. Background technique [0002] Indoor positioning is an important topic in the current positioning technology research, which mainly realizes the positioning of moving objects in indoor space. One of the current positioning methods is to use a two-dimensional code for positioning. Specifically, a plurality of two-dimensional codes are pasted on different positions in the room, and the spatial position is recorded in the two-dimensional codes. When a moving object is positioned, the current position is obtained after scanning and analyzing the two-dimensional codes. However, this method can only be positioned at the position where the two-dimensional code is pasted, which is inconvenient to use and has a small positioning range. Contents of the invention [0003] In view of this, the present invention provides an indoor positioning m...
