Embodiment 1

[0028] refer to figure 1 , the present invention realizes a method for indoor geomagnetic positioning by deploying magnets, 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 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 smart phone in step S1. During the collection process, cover the area to be collected with the smart phone and move across the field, and use the built-in accelerometer and gyroscope of the smart phone to calculate and collect while collecting The relative position of the person. The acquisition process is simple, the equipment cost is low, the acquisition difficulty is low, no professional training is required, and the relative position is calculated while collecting geom...

Abstract

The invention discloses a method for realizing indoor geomagnetic positioning by deploying magnets. Through a minimum deployment mode, the characteristics of the geomagnetic fingerprint are enhanced,and the geomagnetic positioning precision is effectively improved. According to the data collection mode of collecting the geomagnetic fingerprint, the region with insufficient geomagnetic fingerprintcharacteristics is calculated and the geomagnetic fingerprint is collected again, the region with poor geomagnetic fingerprint characteristics is accurately calculated, the magnet is supplemented anddeployed in a targeted manner, and the cost is reduced. According to the magnet deployment method provided by the invention, the characteristics of the geomagnetic fingerprint are effectively improved, so that the application range of geomagnetic positioning is enlarged, and the geomagnetic positioning can be used in a semi-open or outdoor environment.

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 is no large-scale interior decoration or other 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 tech...
