Embodiment Construction
[0020] A method for counting people flow based on CSI and DTW, the process is as follows figure 1 As shown, the specific implementation steps are as follows:
[0021] 1) Environmental deployment: CSI-based people flow statistics require WiFi signals to be covered at passages or entrances and exits. The equipment is an access point (Access Point, AP) and a monitoring point (Monitoring Point, MP), both of which are equipped with Intel WirelessLink 5300 agn (IWL5300) wireless network card, which has 3 antennas. The AP and MP are placed on both sides of the channel, the AP sends data, and the MP receives data. The layout is as follows: figure 2 shown.
[0022] 2) CSI raw data sequence collection: In the template training stage, set the flow of people as W people, W=0, 1, 2, 3, 4, 5..., and let them follow figure 2 The queues shown pass through the covered WiFi channels or entrances and exits, respectively. The MP collects CSI raw data from the AP at a sampling rate of 20 Hz,...
