Problems solved by technology

In this triangular centroid positioning algorithm, the position of the positioning target needs to be determined by taking the intersection points of the three ibeacon devices. The calculation of the value of the three points is relatively complicated, and the large number of devices will undoubtedly increase the cost of indoor positioning

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 and 2 As shown, an indoor two-point positioning method based on ibeacon equipment, including steps:

[0018] S1. In the indoor environment, place ibeacon device A and ibeacon device B separately; in order to ensure that the height of the device is basically at the same level as the height of the target mobile phone, keep a distance of about 1.5m between points A and B, and do not set up metal barriers ;

[0019] S2. The user enters the indoor environment area, turns on the Bluetooth of the mobile phone, performs the first positioning calculation, and obtains the distances L1 and L2 from ibeacon device A and ibeacon device B to the target location of the user's mobile phone respectively;

[0020] S3. Draw a circle with the ibeacon device A as the center and the distance L1 as the radius, and draw a circle wit...

Abstract

The invention provides an indoor two-point positioning method based on ibeacon devices. The indoor two-point positioning method comprises the steps that the ibeacon devices A and B are placed indoors; after the target enters, acquiring distances L1 and L2 from the ibeacon equipment A and the ibeacon equipment B to the target position respectively; drawing a circle by taking the ibeacon equipment A and the ibeacon equipment B as circle centers and the distances L1 and L2 as radiuses to obtain two intersection points M and N; moving the target position for a small distance, and obtaining the distances L3 and L4 from the ibeacon equipment A and B to the target position; drawing a circle by taking the ibeacon equipment A and the ibeacon equipment B as circle centers and distances L3 and L4 as radiuses to obtain two intersection points M1 and N2; through the intersection points obtained twice, combining two points which are closer to each other to form an MM1 vector and an NN1 vector; the MM1 vector and the NN1 vector are compared with the direction pointed by the sensor of the mobile phone, the vector in the same direction is the correct target position movement vector, the correspondingly obtained intersection point is the target position, and the positioning method is extremely convenient and accurate.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to an indoor two-point positioning method based on an ibeacon device. Background technique [0002] At present, for some large underground parking lots, large shopping malls and other places, due to the poor signal quality of the indoor environment, it is impossible to accurately locate the problem. The positioning solution based on iBeacon is currently the most commonly used indoor positioning method. It uses the triangular centroid positioning algorithm to Realize positioning, use three iBeacon devices as beacon nodes, obtain the coordinate position on the plane model corresponding to the device, and finally obtain the position of the unknown node measured. In the circular positioning model, in theory, if the physical distance from the unknown node to the three beacon nodes is known, then three circular models are established with the three beacon nodes as t...
