Problems solved by technology

[0005] Since the internal facilities of the target area are often changed, the previously established fingerprint database and indoor signal field strength mathematical model cannot be used for indoor positioning of the changed target area, so the fingerprint database of the target area needs to be updated in time when the facility changes
However, for the existing fingerprint data update of the target area, the collection team generally collects the change of the clutter signal in the target area on site to determine whether the target area needs to update the fingerprint data, or to periodically re-collect the clutter signal for fingerprint data update. However, the practice of collecting changes in clutter signals on the spot obviously requires huge manpower and material resources, and is inefficient, but the method of regular collection cannot effectively and timely know the clutter signal situation in the target area
[0006] Obviously, the existing method for judging the fingerprint data update of the target area cannot meet the two requirements of low cost and high timeliness at the same time, and there are major defects

Abstract

The invention discloses a fingerprint data updating judgment method and device of a target area. The method comprises the following steps: determining facility change data of the target area, wherein the facility change data is used for representing facility change conditions in the target area; determining fingerprint data updating necessity information of the target area according to the facility change data of the target area, wherein the fingerprint data updating necessity information is used for indicating whether the fingerprint data of the target area needs to be updated or not. Therefore, the fingerprint data updating necessity of the target area can be determined through the facility change data of the target area, and the relevance between the facility change of the target area and the clutter signal change is effectively utilized, so that the timeliness and accuracy of fingerprint data updating judgment are improved, a large amount of manpower and material resources do not need to be consumed, ad the method has the advantages of low cost and high efficiency.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a method and device for updating and judging fingerprint data in a target area. Background technique [0002] The current popular indoor positioning technology is usually completed through the following two stages: [0003] 1. Offline learning. The mathematical model of indoor signal field strength is established by offline collection of indoor spatial clutter signals with location tags as fingerprint data. [0004] Second, online positioning. The purpose of positioning is achieved by comparing the clutter signal collected in the positioning request with the fingerprint data in the fingerprint database. [0005] Since the internal facilities of the target area are often changed, the previously established fingerprint database and indoor signal field strength mathematical model cannot be used for indoor positioning of the changed target area, so the fingerprint datab...
