Embodiment Construction

[0047] Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. The order of operations can be rearranged. A process may be terminated when its operations are complete, but may also have additional steps not included in the figure. A process may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0048] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present.

[0049] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms "a", "an" and "an" are intended to include the plural unles...

Abstract

The invention belongs to the field of indoor positioning and particularly relates an indoor positioning method and system and a server. The method comprises A, an offline training step of collecting training samples and establishing a fingerprint database based on the training samples; B, an online positioning step of receiving RSS data of to-be-positioned terminals, calling the fingerprint database, finishing real-time position operation according to received RSS data, and returning an operation result to the to-be-positioned terminals; and C, an running maintenance step of carrying out active and/or passive sensing on maintenance terminals in a positioning space, continuously collecting fingerprint data of the maintenance terminals, and updating the fingerprint database periodically or aperiodically based on the fingerprint data. The method, the system and the server have the advantage that the stability and accuracy of a positioning process are ensured by continuously updating the fingerprint database.

Description

technical field [0001] The invention belongs to the field of indoor positioning, and in particular relates to an indoor positioning method, server and system. Background technique [0002] Localization in indoor environments has always been an area with many unsolved problems. Common outdoor positioning facilities such as GPS do not work effectively inside buildings due to severe signal attenuation and multipath effects. Positioning accuracy is also a problem. GPS may be able to point out which building the mobile device is in, but in indoor scenarios, people hope to get a more accurate indoor position, which requires more precise map information and higher positioning accuracy. [0003] At present, there is also the practice of building a complete set of infrastructure for positioning indoors, but this requires a lot of cost, including the spectrum resources occupied by positioning signals, additional hardware embedded in mobile devices for sensing positioning signals, ins...
