Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] At present, the accuracy of indoor positioning methods is low, and the generalization ability is not high. Based on this, embodiments of the present invention provide an indoor positioning method, device and system, which can be applied to indoor positioning and positioning in fixed areas. To facilitate the understanding of this embodiment, an indoor positioning method disclos...

Abstract

The invention provides an indoor positioning method, a device and a system, wherein the method comprises the following steps: detecting a wireless network received by a user terminal and correspondingsignal intensity; converting signal intensity in to a corresponding coding image; inputting the coding image into a prebuilt indoor positioning model, and determining positioning information of the user terminal according to an output result. According to the method provided by the invention, the signal intensity is converted into the coding image, and indoor positioning is executed through a model obtained by training of a deep convolutional neural network, thus, indoor positioning precision is improved.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to an indoor positioning method, device and system. Background technique [0002] In many indoor and outdoor environments, such as offices, shopping malls, stations, etc., if the user's precise location information can be obtained, the user can be provided with interesting applications and services. In recent years, the explosive growth of mobile devices has stimulated users' demand for accurate indoor positioning, but due to the unavailability of GPS (Global Positioning System, Global Positioning System) indoors, accurate indoor positioning is still a challenge. [0003] The existing indoor positioning is mainly researched around Wi-Fi (Wireless-Fidelity, wireless fidelity) fingerprint technology, most of which use the RSSI (Received Signal Strength Indication, received signal strength indication) method; but this method cannot solve the problem of location sampl...
