Embodiment 1

[0028] see figure 1 , the present invention is a method for realizing indoor geomagnetic positioning by deploying a magnet, comprising the following steps:

[0029] Step S1: take a smart phone with a high-precision magnetic sensor; use a high-end smart phone with a high-precision magnetometer to collect the area that needs to be located, in order to reduce the economic cost and time cost of the collection work.

[0030] Step S2: Collect the geomagnetic information and relative position of the area to be located by the smartphone in step S1. During the collection process, cover the entire field of the area to be collected by holding the smartphone, and use the built-in accelerometer and gyroscope of the smartphone to calculate and collect while collecting. The relative position of the personnel. The acquisition process is simple, the equipment cost is low, the acquisition difficulty is low, no professional training is required, and the geomagnetic information is collected and ...

Abstract

The invention discloses a method for realizing indoor geomagnetic positioning by deploying magnets. Through the minimum deployment method, the characteristic of geomagnetic fingerprints is enhanced, and the accuracy of geomagnetic positioning is effectively improved; the data collection method of collecting geomagnetic fingerprints, calculating geomagnetic fingerprint characteristic insufficient areas and re-collecting geomagnetic fingerprints proposed by the present invention can accurately calculate Out of the areas with poor geomagnetic fingerprint characteristics, the magnets are deployed in a targeted manner, which reduces the cost; because the magnet deployment method proposed in the present invention effectively improves the characteristics of the geomagnetic fingerprints, it increases the scope of application of geomagnetic positioning, making it possible to It is possible to use geomagnetic positioning in semi-open or outdoor environments.

Description

technical field [0001] The invention relates to the technical field of indoor positioning and indoor navigation, in particular to the technical field of indoor geomagnetic positioning. Background technique [0002] At present, indoor positioning technology based on geomagnetic signals has become the focus of attention. The reason is that the geomagnetic signal is very stable, and there is no non-line-of-sight communication problem that plagues radio wave signals such as iBeacon signals and Wi-Fi signals. As long as the indoor space results remain relatively stable and there are no large-scale interior decoration activities that change the distribution of indoor geomagnetic signals, the geomagnetic fingerprint features remain largely unchanged. However, indoor geomagnetic positioning also has the following problems: [0003] 1. Not all indoor locations have strong geomagnetic fingerprint features, so geomagnetic positioning algorithms usually use deep learning technology to...
