| description | The invention discloses a bow angle detection method based on CSI signal intensity in wifi. The method comprises the following steps: step one, configuring an AP and MP; constructing an experimental environment; preparing a commercial normal wireless network card driver, and a wifi router supporting 802.11n or above protocol; and configuring a CSI environment; step two, collecting data; and step three, processing the data; extracting a feature value reflecting a bow action by analyzing and processing channel state information CSI, and establishing a harmonic model; and finally classifying thebow angle action by utilizing a classifier, identifying and correcting the sitting posture, and realizing synchronous adjusting of the waist and cervical vertebra of the user; and reflecting the waistbending degree through the bow angle. The method disclosed by the invention is simple, free from carrying any sensor equipment and high in real time.
