Embodiment Construction

[0041] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and that the embodiments are not intended to limit the scope of the invention. Rather, these embodiments are provided to enable those skilled in the art to more thoroughly understand the present invention.

[0042] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and There are three cases of B. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0043] Considering the cost and the difficulty of implementation, the present invention adopts a...

Abstract

The invention discloses an indoor positioning system, a corresponding positioning device and a positioning method. The system comprises a signal acquisition unit (100), which is used for acquiring indoor iBeacon base station signals and obtaining RSSI signal values. An offline database building unit (200) for building a position fingerprint database according to a plurality of RSSI signal strengthdata and reference point coordinate information of an indoor environment, and storing the position fingerprint database in a positioning server; a coordinate calculation unit (300) is configured to invoke the position fingerprint database, perform coordinate matching calculation on the RSSI signal strength vector acquired in real time, and obtain indoor coordinates. The algorithm of the inventionis simplified and can meet the precision requirements of most indoor positioning scenes.

Description

technical field [0001] The present application relates to the technical field of indoor positioning and navigation, in particular to a Bluetooth-based indoor positioning system, positioning device and positioning method. Background technique [0002] Accurately obtaining the location information of the target has shown important research significance in many research fields. With the development of research, outdoor positioning technology based on GPS and cellular network has been developed relatively mature. [0003] GNSS systems such as GPS have shown great advantages in outdoor positioning, but when moving from outdoors to indoors, GPS signal strength and quality will drop sharply, because GPS becomes unfeasible for indoor positioning. Due to the relative complexity of indoor positioning, indoor positioning technology is interfered by many environmental and human factors, including building design, indoor environment layout and personnel movement. These factors will aff...
