Title:
VORONOI DIAGRAM BASED INDOOR SPACE POSITIONING
Document Type and Number:
WIPO Patent Application WO/2019/141177
Kind Code:
A1
Abstract:
An indoor positioning apparatus, a mobile device comprising the indoor positioning apparatus, a positioning method in an indoor space that can be used for a mobile device, and a computer-readable medium. The indoor positioning apparatus comprises: a photography unit (10, 102) for capturing image information of at least one illuminator (206) of multiple illuminators (206), wherein the multiple illuminators (206) are located at the top of an indoor space; a storage unit (30) for at least storing information of an illuminator Voronoi diagram, wherein the illuminator Voronoi diagram comprises multiple Voronoi diagram units, each of the Voronoi diagram units comprises a generation element, and each generation unit of the multiple Voronoi diagram units is located in each projection of the multiple illuminators (206) on a horizontal plane of the indoor space; and a processor (20) for receiving the image information and the information of the illuminator Voronoi diagram, and calculating the position of the photography unit (10, 102) in the indoor space based on the image information and the information of the illuminator Voronoi diagram. With the indoor positioning apparatus, wireless communication or visible light communication is not needed, and thus the illuminators (206) are not required to have an optical communication or wireless communication function, having strong universality and being low in cost; furthermore, 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.
