Abstract

The invention discloses an indoor positioning method and an indoor positioning device. The method comprises steps: multiple beacon nodes with known coordinates are arranged; based on an indoor RSSI ranging experiment, a transformation relation between the RSSI value and a distance is built; coordinate data of one or more beacon nodes are sent to an unknown node; and according to the RSSI value of each beacon node detected by the unknown node, the received coordinate data and the transformation relation, coordinates of the unknown node are determined. The problem that the indoor positioning method in related technology is low in accuracy is solved, specific coordinates can be positioned, the corresponding relation between the RSSI and the distance in positioning ranging is obtained through experimental data field acquisition in an indoor scene in need of positioning, the relation is more in line with the actual condition of the indoor scene, and more accuracy is achieved than using a wireless signal propagation theoretical model.

Description

technical field [0001] The present invention relates to the technical field of wireless communication positioning, in particular to an indoor positioning method and device. Background technique [0002] With the rapid development of modern communication, network, Global Positioning System (Global Position System, GPS), ubiquitous computing, distributed information processing and other technologies, location-aware computing and location-based services (Location Based Services, LBS) are becoming more and more popular in practical applications. more important. The practicality and necessity of precise positioning technology in many indoor scenarios has become increasingly evident. [0003] GPS is currently the most widely used and successful positioning technology. The basic principle is to use the instantaneous position of the high-speed moving satellite as the known original data, and then calculate the distance between the receiver and each satellite according to the time ...
