Problems solved by technology

The positioning method based on received signal strength (RSS) involves the transmission of electromagnetic waves or sound waves in the indoor space, which is easily affected by multipath effects, which is not conducive to the improvement of positioning accuracy
High-precision positioning requires high-density arrangement of signal sources, which also leads to increased costs

Abstract

An embodiment of the invention provides an indoor positioning device comprising the following parts of a photography unit for capturing image information of at least one of multiple illuminators; a storage unit for at least storing information of Voronoi diagrams of the illuminators, wherein the Voronoi diagrams of the illuminators comprise multiple Voronoi diagram units respectively correspondingto multiple generation elements, and the multiple generation elements comprise projections of central points of luminous components of the multiple illuminators on a horizontal plane of the indoor space; and a processor for receiving the image information and the information of the Voronoi diagrams of the illuminators, and calculating the accurate position of the photography unit in the indoor space based on the image information and the information of the Voronoi diagrams of the illuminators. The indoor positioning device provided by the embodiment of the invention needs no wireless communication or visible light communication. Since the transmission of electromagnetic or sound wave signals is not involved, the influence brought about by a multi-path effect can be reduced or eliminated.

Description

technical field [0001] The present invention mainly relates to the technical field of positioning, and in particular, relates to an indoor positioning device, a mobile device including the indoor positioning device, and a positioning method for the mobile device in an indoor space. Background technique [0002] Currently, common indoor positioning technologies include visible light positioning technology and positioning methods based on received signal strength (RSS). Visible light positioning technology generally requires that lighting fixtures have communication functions to be able to send location information or identifiers of lighting fixtures to positioning devices. For this purpose, it is necessary to install wireless communication equipment on lighting fixtures, or to With visible light communication capability, it is possible to transmit specific identifiers through changes in luminous parameters (such as brightness, color, spectrum). Therefore, the visible light p...
