Abstract

The present invention provides a positioning method and system. The method comprises: performing communication between an object to be positioned and anchor nodes participating in positioning in a positioning area, and acquiring wireless signal features used for positioning when the communication between the object to be positioned and each anchor node participating in positioning; dividing every two anchor nodes of the anchor nodes participating in positioning into one positioning group, and performing the following operations for each positioning group: determining a reference position between two anchor nodes of one positioning group, and determining a position relationship between the object to be positioned and the reference position according to the wireless signal features between the object to be positioned and the two anchor nodes; and determining a position relationship between the object to be positioned and the reference position according to all the obtained positioning groups, and determining a position of the object to be positioned.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method and system. Background technique [0002] Glossary: [0003] (1) Anchor node (or beacon node) refers to a pre-arranged node with communication capabilities. Usually, one or more anchor nodes need to be set in the area to be positioned for positioning; the number of anchor nodes and The layout will affect the positioning accuracy. [0004] (2) The target to be positioned refers to a device with communication capability, which performs positioning by communicating with the anchor node after entering the area to be positioned. In the embodiment of the present invention, the anchor node can be any device with communication capabilities, including but not limited to: smart bracelets, mobile terminals, smart watches, etc. [0005] Positioning is a very commonly used technology, and precise positioning is the basis of many technical fields such as nav...
