Title:
METHOD AND DEVICE FOR CLASSIFYING POSE BY USING ULTRA WIDEBAND COMMUNICATION SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/063619
Kind Code:
A1
Abstract:
The present disclosure provides a method by which an electronic device classifies a pose by using a UWB signal. The method of the present disclosure may comprise the steps of: using a trained first CNN model so as to acquire first prediction data for classifying whether a signal corresponding to a UWB CIR is a LOS signal or an NLOS signal on the basis of UWB CIR data; using, if the signal is classified as the LOS signal, a trained second CNN model so as to acquire second prediction data for classifying a pose on the basis of sensor data corresponding to the UWB CIR data; using, if the signal is classified as the NLOS signal, a trained third CNN model so as to acquire third prediction data for classifying the pose on the basis of the sensor data corresponding to the UWB CIR data; using a first filtering method so as to filter at least two from among the first prediction data, the second prediction data, and the third prediction data; and classifying the pose on the basis of the filtered data.
