    • The disclosure provides a gesture recognition apparatus and method. The gesture recognition apparatus includes an ultrasound transmitter, an ultrasound receiver, a dividing module, a computing module, a gesture library, and a recognition module. The dividing module is configured to divide reflected ultrasound signals into a plurality of frames according to time intervals. The computing module is configured to obtain an eigenvalue of each frame. The classifying module is configured to filter the eigenvalues to obtain gesture eigenvalues, and to obtain a matrix of probabilities of the gesture eigenvalues. The recognition module is configured to search reference matrices of probabilities from the gesture library for matching with the matrix of probabilities, and to recognize the gesture eigenvalues as a reference gesture corresponding to the reference matrix of probabilities if the reference matrix of probabilities is found.
    • 本公开提供了一种手势识别装置和方法。 手势识别装置包括超声波发射器,超声波接收器,分割模块,计算模块,手势库和识别模块。 分割模块被配置为根据时间间隔将反射的超声信号分成多个帧。 计算模块被配置为获得每个帧的特征值。 分类模块被配置为过滤特征值以获得手势特征值,并且获得姿态特征值的概率矩阵。 识别模块被配置为搜索来自姿势库的概率的参考矩阵以便与概率矩阵匹配,并且如果找到概率的参考矩阵,则将手势特征值识别为与概率参考矩阵相对应的参考手势。
