Abstract

The embodiment of the invention provides a positioning method and device based on virtual coordinates, and relates to the technical field of positioning. The positioning method comprises the followingsteps that positioning source is positioned according to a plurality of actual coordinates of a plurality of positioning base stations to obtain plane coordinates of the positioning source in space;the positioning source is positioned according to virtual coordinates, the actual coordinates and the plane coordinates to obtain three-dimensional coordinates of the positioning source in space, wherein any of the positioning base stations has virtual coordinates not on the same plane; and the position of the positioning source in space is determined based on the plane coordinates and the three-dimensional coordinates. Precise positioning source in space can be realized by the plane coordinates and the three-dimensional coordinates, and the technical problems that the positioning bases station are located in the same plane and the positioning source can not be accurately positioned are solved.

Description

technical field [0001] The present application relates to the field of positioning technology, and in particular, to a positioning method and device based on virtual coordinates. Background technique [0002] In the current indoor precise positioning technology, by installing multiple positioning base stations indoors, when the positioning source transmits the positioning signal, the positioning terminal uses the multiple positioning base stations to collect the positioning signal, so that the positioning source can be accurately positioned. SUMMARY OF THE INVENTION [0003] The present application provides a positioning method and device based on virtual coordinates to solve the technical problem that the positioning source cannot be accurately positioned when the positioning base stations are located on the same plane. [0004] In order to achieve the above purpose, the embodiments of the present application are achieved in the following ways: [0005] In a first aspect...
