Abstract

Embodiments of the present disclosure provide a sitting posture detection method and apparatus based on UWB, a device and a storage medium, which are applied in the technical field of intelligent analysis. The method comprises steps of: by a UWB signal receiver, receiving and amplifying a pulse signal to obtain a first pulse signal, adjusting the phase of the first pulse signal of a corresponding frame based on the difference between the average phase of a reference pulse signal and the phase of the reference pulse signal of any frame, and using a cascade filter to remove noise and increase the signal-to-noise ratio of the received baseband signal to obtain a second pulse signal; using a sudden change in the amplitude of the second pulse signal and/or Doppler information as a sign of a sitting posture change, and determining target distance and angle information of different sitting postures; and, splicing the target distance and angle information as a joint feature and inputting the joint feature into an SVM classifier to obtain a result of sitting posture detection. In this way, the accurate location of a target object can be accurately tracked, and the sitting posture of an individual can be monitored in real time without involving the user's privacy.
