传统输入设备无法满足人们的随意性输入需求。为此,提出一种基于陀螺仪传感器的三维手势识别方案。硬件架构由陀螺传感器信息采集模块、单片机信息处理模块以及射频无线传输模块组成。利用多功能滤波器进行数据预处理,设计一种基于角度的特征提取算法,提取三维手势特征。实验结果表明,该方案的平均识别率达到99.3%,能较好地实现3D空间的鼠标输入功能和键盘输入功能。
Traditional input devices can not meet people’s random input requirements. Therefore, a three-dimensional gesture recognition scheme based on gyro sensor is proposed. The hardware architecture is composed of gyro sensor information acquisition module, SCM information processing module and RF wireless transmission module. The multi-function filter is used to preprocess the data, and an angle-based feature extraction algorithm is designed to extract the three-dimensional gesture features. Experimental results show that the average recognition rate of the scheme reaches 99.3%, which can realize the mouse input function and keyboard input function in 3D space well.
