Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a method for solving area misjudgment based on indoor positioning includes the following steps:

[0037] (1) Select multiple reference paths that need to collect fingerprint data in the positioning service area. The selected reference path is a straight line. It is necessary to know the starting point and end point of each straight line reference path, and the signal acquisition equipment records the position of the starting point and end point of the reference path. coordinates, and store the fingerprint data on the reference path with the coordinates of the starting point and the end point of the straight line reference path as the file name;

[0038] (2) The signal acquisition equipment that implements the collection moves at ...

Abstract

The invention discloses a region misjudgment solution method based on indoor positioning. The region misjudgment solution method comprises the following steps that a reference path with fingerprint data needing to be collected is selected in a positioning service region; the corresponding fingerprint data are collected according to the reference path; channel modeling is carried out on the collected fingerprint data according to the machine learning method; trained fingerprints are scanned, and the identification of all wireless routers and the number of the wireless routers are extracted; the fingerprint information of all positions is ranked according to the signal strength of the wireless routers; traversal is carried out, the fingerprint information of the positions is clustered according to the signals of two wireless routers with the maximum signal strength, and the classification identification is added; after it is confirmed that classifying is finished, position fingerprint databases are integrated again. The region misjudgment solution method is easy to apply, and can well solve the problem of the positioning system region misjudgment.

Description

technical field [0001] The invention relates to the technical field of communication and wireless network, in particular to a method for solving area misjudgment based on indoor positioning. Background technique [0002] With the increasing demand for information services, location-based services have become one of the most popular service demands. People are no longer satisfied that they can only enjoy location-based information services outdoors, and the demand for indoor positioning is becoming increasingly strong. The emergence and development of the satellite positioning and navigation system has enabled people to have a technical method to obtain the geographic location attributes of things with unprecedented reliability and precision in a vast outdoor space, and has basically solved the problem of accurate positioning in outdoor space. And it has been widely used in the fields of military, resources, transportation, agriculture, animal husbandry and fishery, environm...
