Problems solved by technology

For positioning devices in the same positioning mode, the number of deployed positioning devices may be insufficient due to unbalanced deployment, high cost, or the distribution characteristics and signal propagation characteristics of the positioning devices themselves. The signal coverage of the positioning equipment in this positioning mode is incomplete, and there are areas where there is no signal or the signal is weak and cannot be located. Once the object to be located enters these areas, it will cause positioning failure or inaccurate technical problems.

Embodiment Construction

[0023] The positioning method and device provided in the embodiments of the present application are suitable for electronic map positioning, such as indoor positioning and outdoor positioning.

[0024] In the embodiment of the present application, triangulation positioning technology or fingerprint positioning technology may be used to locate the first positioning information in the positioning mode.

[0025] The "fingerprint" in the fingerprint positioning technology refers to the multipath characteristic signal generated at a certain position after the positioning signal sent by the positioning device (such as Access Point (AP)) is reflected, refracted, etc., which is the positioning device. Fingerprint information at that location. Assuming that the positioning device is an AP, the radio waves emitted by the AP will generate a multipath characteristic signal corresponding to the position at a certain position after reflection and refraction, and the multipath characteristic...

Abstract

The application relates to a positioning method and device. The method comprises the following steps: acquiring first positioning information transmitted by at least two positioning modules of different positioning modes at a point to be positioned; and matching the first positioning information with second positioning information corresponding to a position pre-stored in a pre-storing positioning data fingerprint database to determine positions corresponding to the positioning modes, and acquiring the position of the point to be positioned according to the positions corresponding to the positioning modes. The point to be positioned is positioned through the at least two positioning modules of different positioning modes, thereby solving the problem of low accuracy in positioning of the point to be positioned according to a single positioning mode in the prior art.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a positioning method and device. Background technique [0002] At present, the most mainstream indoor positioning technologies mainly include triangulation positioning and fingerprint positioning. signal source positioning), for example, the positioning mode is wifi positioning, bluetooth positioning, etc. [0003] Because in practical applications, each positioning mode corresponds to a positioning information, if the positioning mode is wifi positioning, the corresponding positioning information is wifi signal, that is, the positioning mode scans the wifi signal sent by the wifi device; if the positioning mode is bluetooth positioning, then The corresponding positioning information is Bluetooth information, that is, the Bluetooth information sent by the Bluetooth device scanned in the positioning mode. For positioning devices in the same positioning mode, th...
