Embodiment Construction

[0053] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0054] It should be noted that the technical solution of the present invention realizes indoor positioning by collecting the signal strength of low-power bluetooth by terminal equipment, and low-power bluetooth has the characteristics of low cost, low power consumption, low delay, and easy deployment. It overcomes the problems of variable deployment location during ordinary Wire...

Abstract

The invention provides an indoor positioning method and device. The method comprises the following steps: first terminal equipment obtains a first Bluetooth signal strength vector, wherein the first Bluetooth signal strength vector includes first signal strength of all access points (APs) received by the first terminal equipment in a current room; the first terminal equipment determines a first position coordinate when receiving the first Bluetooth signal strength vector according to the first Bluetooth signal strength vector and a preset positioning database, wherein the positioning database is used for representing a mapping relationship between different position coordinates and different second Bluetooth signal strength vectors. According to the method provided by the invention, the position coordinate of at least one of the second Bluetooth signal strength vectors corresponding to the first Bluetooth signal strength vector is obtained, and all the position coordinates are correspondingly processed to obtain the first position coordinate, therefore, the indoor quick and accurate positioning of the first terminal equipment is realized.

Description

technical field [0001] The invention relates to positioning technology, in particular to an indoor positioning method and device. Background technique [0002] With the rapid increase of data services and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, mines, etc. , it is often necessary to determine the location information of the mobile terminal or its holder, facilities and objects indoors. However, limited by conditions such as positioning time, positioning accuracy, and complex indoor environments, relatively complete positioning technologies cannot be well utilized at present. [0003] The existing indoor positioning technology has a triangle algorithm. The triangle algorithm is mainly to find the relationship function between signal strength and distance, estimate the distance according t...
