Embodiment Construction
[0051] Below we describe in detail the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily and quickly understood by those skilled in the art, thereby making the protection scope of the present invention more clear clearly defined and defined.
[0052] refer to Figure 1 to Figure 5 , a passive indoor positioning method for network visualization, comprising the following steps:
[0053] Step 1: Build a channel status information data collection platform;
[0054] Step 2: Divide the positioning area into N grids as the basic unit of positioning classification, denoted as L 1 ,...,L N ;
[0055] Step 3: In the offline training phase, the human body maintains a static posture in each grid for a period of time, and collects data packets containing channel state information. The format of each channel state information data is: where F 1 ~F 30 are subca...
