ACTION DETECTION AND RECOGNITION METHOD BASED ON WIRELESS SIGNAL

WIPO Patent Application WO/2016/197648

A1

An action detection and recognition method based on a wireless signal relates to the fields of wireless networks and pervasive computing, in particular to an action detection and recognition method based on a wireless signal. The method utilises interference of a human body motion on a wireless signal, adopts a general purpose wireless device to acquire wireless signal data (201), and extracts a feature associated with the speed of the motion after performing denoising processing on the data, so as to recognize the motion. The method comprises: using one or more general purpose wireless devices to acquire the wireless signal data (201), performing the denoising processing (202) on the wireless data by means of the correlation of multiple channels of wireless signal data, and extracting the features associated with the speed of the human body motion from the wireless data so as to detect and recognize the motion. The basic steps comprise: data acquisition (201), data denoising (202), data segmentation (203), feature extraction (204), model training (205), and motion recognition (206).
