Abstract

The invention provides an indoor positioning method based on Bluetooth and audio. The method includes: in the positioning period, receiving a Bluetooth signal and an audio signal transmitted by each positioning node in a preset positioning array, determining a plurality of positioning Bluetooth signals according to the signal intensity value of the Bluetooth signal; determining a current positionarea of the to-be-positioned terminal based on each positioning Bluetooth signal; and selecting the audio signal transmitted by each positioning node corresponding to the position area from the received audio signals, calling a preset audio positioning algorithm, and calculating the audio signal transmitted by the selected positioning node corresponding to the position area to obtain the current position of the terminal to be positioned. By applying the indoor positioning method based on Bluetooth and audio provided by the invention, the indoor positioning area can be expanded, and indoor positioning with wider positioning coverage and higher precision is realized.

Description

technical field [0001] The present invention relates to the field of spatial positioning, in particular to an indoor positioning method and device based on bluetooth and audio. Background technique [0002] With the rapid development of data services and multimedia services, people's demand for positioning and navigation continues to increase. more people's attention. At present, people can use GPS, Beidou and other satellite positioning technologies to achieve accurate positioning outdoors, but indoors, due to the occlusion of buildings such as house walls, satellite signals will be greatly attenuated, resulting in serious inaccurate indoor positioning and reduced positioning accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an indoor positioning method based on Bluetooth and audio, according to the signal strength value of the Bluetooth signal transmitted by the positioning node in the positioning node...
