Abstract

The invention discloses a three-dimensional space positioning method and system, and the method comprises the steps: constructing a three-dimensional coordinate system XYZ, arranging a UWB transmitting base station and a first Bluetooth transmitting base station at the original point of the coordinate system, arranging a second Bluetooth transmitting base station at the coordinate system point (0, 0, L1), and arranging a third Bluetooth transmitting base station at the coordinate system point (3pi / 2,0,L1); enabling the to-be-positioned object to receive communication information of each Bluetooth transmitting base station through the Bluetooth receiving equipment, and obtain an RSSI value in the communication information; determining the distance from the to-be-positioned object to each Bluetooth transmitting base station according to each RSSI value; determining alpha and beta in the coordinates of the to-be-positioned object according to the distance from the to-be-positioned object to each Bluetooth transmitting base station and L1; and enabling the Bluetooth equipment in the object to be positioned to receive the electromagnetic wave signal of the UWB transmitting base station, and determine the distance from the object to be positioned to the original point according to the propagation time of the electromagnetic wave signal. According to the invention, by fusing UWB and Bluetooth base station positioning technologies, the purposes of improving the precision and slowing down the cost rise are achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional space positioning, in particular to a three-dimensional space positioning method and system. Background technique [0002] In recent years, more and more spatial positioning technologies have been developed, and have been widely used in industrial, commercial and medical fields, and the market share is still growing. Cost and positioning accuracy are an irreconcilable contradiction. [0003] The current mainstream positioning solutions mainly include: ultrasonic positioning, infrared positioning, WiFi base station positioning, low-power Bluetooth iBeacon base station positioning, mobile base station positioning, global positioning system (global position system, GPS) positioning, ultra wide brand (ultra wide brand, UWB) positioning. Among them, WiFi base station positioning, iBeacon Bluetooth base station positioning, mobile base station positioning, global positioning system GPS positi...
