Zusammenfassung:An embodiment of the present invention is to provide a hand gesture classification apparatus capable of extracting a feature of a hand gesture using sound waves in an inaudible frequency band, and classifying the hand gesture based on the extracted feature of the hand gesture. The hand gesture classification apparatus includes: a sound wave processing unit for generating a sound wave image by analyzing a reflected sound wave generated based on a hand gesture with respect to a reference sound wave in an inaudible frequency band, by intensity for each frequency band with respect to time; a standard hand gesture determination unit for determining a standard hand gesture corresponding to the sound wave image from a standard hand gesture population through a hand gesture model generated by machine-learning the sound wave image population; and a hand gesture model adjusting unit for adjusting the hand gesture model based on the degree of matching between the hand gesture and the standard hand gesture in a process of determining the standard hand gesture. 본 발명은 손동작 분류 장치에 관한 것이다. 본 발명은 비가청 주파수 대역의 기준 음파에 관한 손동작을 기초로 생성된 반사 음파를 시간에 대한 주파수 대역별 세기로 분석하여 음파 이미지를 생성하는 음파 처리부, 음파 이미지 모집단을 기계학습하여 생성된 손동작 모델을 통해 표준 손동작 모집단에서 음파 이미지에 해당하는 표준 손동작을 결정하는 표준 손동작 결정부, 및 표준 손동작의 결정 과정에서 손동작과 표준 손동작 간의 정합도를 기초로 손동작 모델을 조절하는 손동작 모델 조절부를 포함한다.
