AI Technical Summary

Problems solved by technology

The fingerprint information update method provided by the existing technology will update the fingerprint information corresponding to all locations at the same time, and the update period is fixed. The selection of the update location and the setting of the update period do not have dynamic adaptive characteristics, resulting in longer update time and a waste of system resources.

Abstract

The present invention discloses an update method, device and system of fingerprint information in indoor location, and a storage medium. The method comprises the steps of: checking fingerprint aging qualification time of each position node in a target area at intervals of preset time; when the fingerprint aging qualification time of each position node is 0, determining whether the location information and actual position information collected by the position nodes are in a preset error range or not; if yes, allowing the fingerprint information of the position nodes not to perform update process, and regulating the fingerprint information update period and fingerprint aging qualification time of the position nodes according to a preset first update rule; if not, performing update processingfor the fingerprint information of the position nodes, and regulating the fingerprint information update period and the fingerprint aging qualification time according to a preset second update rule.The update method, device and system of fingerprint information in indoor location, and the storage medium can adaptively select position nodes requiring updating of the fingerprint information and adaptively regulate the fingerprint information update period of the position nodes.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to a method, device, computer-readable storage medium and system for updating fingerprint information in indoor positioning. Background technique [0002] In recent years, the development of indoor positioning technology has become more and more mature. Indoor positioning is a technology to obtain the position information of indoor target objects. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form a set of indoor position positioning system. The matching method is an important means in indoor positioning. The fingerprint-based positioning technology uses the signal strength vectors of different access points (APs) received at different locations as the fingerprints of the corresponding locations, and gathers the fingerprints of different locations to form an indoor location. The fingerp...
