Positioning method based on indoor positioning and device for positioning method

Abstract

The invention discloses a positioning method based on indoor positioning. The method comprises the following steps: (a) receiving data packets sent by at least two Bluetooth base stations so as to obtain signal intensity value included in the data packets; (b) according to the signal intensity value, calculating distance value from at least two Bluetooth base stations and a mobile terminal; (c) according to the calculated distance value, obtaining a positioning point coordinate of a user holding with the mobile terminal in relative to the Bluetooth base stations; (d) obtaining the moving distance of the user according to an acceleration sensor, and obtaining the moving direction of the user according to a geomagnetic sensor, so as to obtain an inertial navigation positioning point coordinate corresponding to relative displacement of the user; (e) judging if the user is moving at present; if it is, executing step (f); or, executing step (g); (f), performing the dynamic compensation for many times on the inertial navigation positioning point through the positioning point coordinate of the user in relative to the Bluetooth base stations; (g) alternating the inertial navigation positioning point through the positioning point coordinate of the user in relative to the Bluetooth base stations, and compensating the inertial navigation positioning point coordinate one time.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to a positioning method and device based on indoor positioning, and a mobile terminal using the positioning device. Background technique [0002] With the development of current technology, the positioning technology of GPS and mobile phone base stations has gradually been popularized and used on mobile terminals. Users obtain related conveniences by using positioning and navigation applications. [0003] GPS positioning technology is a positioning technology based on synchronous clocks sent by multiple satellites. The premise of accurate positioning is that the user needs to be located in an outdoor open environment that can receive satellite signals; the positioning technology of mobile phone base stations is a technology that uses multiple This technology can be applied indoors or outdoors, but the positioning technology of mobile phone base stations has the f...

Problems solved by technology

In order to improve the stability of positioning, the data packets of the obtained Bluetooth base station are filtered. In view of the fact that filtering will cause positioning delay while improving the positioning stability, the combination of Bluetooth base station and inertial navigation is adopted to solve the existing problems.
