Abstract

本发明属于信号分类与预测技术领域，公开了一种手指运动跟踪系统及方法。系统配置多个采集器获取手指的表面肌电信号数据集；关节数据采集模块获取手指关节角度数据集；数据分解模块接收表面肌电信号数据集并输出每一采集器对应的表面肌电信号子集；Myo编码模块与每一数据分解模块通信连接并接收每一数据分解模块输入的表面肌电信号子集，输出表面肌电信号与肌肉映射关系的矩阵并被Myo解码模块接收后输出表征表面肌电信号与关节角度数据的矩阵。Myo编码模块及Myo解码模块均配有自注意力层，所述方法执行跟踪系统将获取的数据集经自注意力层分别输出表征sEMG信号与肌肉映射以及关节角度的矩阵，实现了连续动作识别且网络复杂度低。
