Abstract

The present invention discloses a WiFi positioning method. The method comprises a 100th step of acquiring signal strength data of a signal sent by a to-be-detected client that is received by each wireless access point in a detection region; a 200th step of inputting the signal strength data acquired in the 100th step into an input data layer of a positioning model; and a 300th step of calculating the signal strength data according to a network layer of the trained positioning model, outputting a position prediction set in an output layer of the positioning model, and determining a position corresponding to the prediction position tag with the maximum probability value in the position prediction set as a position at where the to-be-detected client is, wherein the position prediction set comprises a prediction position tag and a corresponding probability value. The positioning model in the present invention uses a trained depth neural network, and the depth neural network is trained by training massive sampling data, so that the positioning accuracy and precision are improved.

Description

Technical field [0001] The invention relates to the technical field of wireless local area networks, in particular to a WiFi positioning method, a server and a positioning model construction method. Background technique [0002] At present, the world-wide positioning technologies mainly include GPS positioning, Wi-Fi positioning, Bluetooth positioning, etc. GPS positioning is mainly used outdoors, and Wi-Fi and Bluetooth positioning can be used indoors and outdoors. Since Wi-Fi positioning is relatively mature, the specific content of the present invention will be introduced below with the background of Wi-Fi positioning technology. With the popularization of wireless routers, most public areas have achieved a dozen or even dozens of WiFi signal coverage at present, and these routers continuously send their physical addresses and signal strengths while spreading WiFi signals around. Information, as long as it is within its signal coverage, even if you don’t know the Wi-Fi passwo...
