Positioning method and device, terminal and server

Abstract

The embodiment of the invention discloses a positioning method and device, a terminal and a server. The method comprises the following steps: after receiving a first positioning request, carrying out similarity matching on a first Bluetooth fingerprint information set in the first positioning request and fingerprint information in a target fingerprint database corresponding to a target position to determine a target similarity, and responding to a condition that the target similarity is greater than or equal to a preset threshold value; and determining the target position information of the target position as the first position information of the first terminal. Wherein the first Bluetooth fingerprint information set is a fingerprint information set of Bluetooth signals collected by the first terminal at the current position. By means of the method, large-scale and low-cost indoor positioning can be achieved, and the positioning requirement of a terminal running part of an operating system (such as an IOS system) is met.

Description

technical field [0001] The present invention relates to the field of positioning, in particular to a positioning method, device, terminal and server. Background technique [0002] Indoor positioning 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. For some related industries (such as the distribution industry), how to perform large-scale and low-cost indoor positioning has become an urgent problem to be solved. [0003] In the prior art, the wireless local area network fingerprint positioning method is usually used to locate the terminal equipment indoors, but this positioning method needs to read the fingerprint information of the wireless local area network signal collected by the terminal equipment during positioning, and some operating systems (such as IOS System) terminal devices usually do not allow applications to rea...

Problems solved by technology

[0003] In the prior art, the wireless local area network fingerprint positioning method is usually used to locate the terminal equipment indoors, but this positioning method needs to read the fingerprint information of the wireless local area network signal collected by the terminal equipment during positioning, and some operating systems (such as IOS System) terminal devices usually do not open the reading authority of WLAN signal fingerprint information to applications, so the existing technology cannot perform indoor positioning on terminal devices running some operating systems (such as IOS system), and there are certain limitations.
