| 针对建立手指触键运动自适应曲线的完整描述,提出了一种基于Leap motion空间3D体感传感器的新型测量方法。首先引入手指运动偏角的概念,建立手指触键运动模型并分布对齐坐标系;然后,根据新型测量方法,进行手指触键动作捕捉与运动特征点选取;最后运用不同的拟合模式在置信区间为95%的条件下处理手指触键动作数据,建立手指触键运动特征描述自适应函数。该函数针对不同长度的人手可为其提供准确的钢琴弹奏触键运动曲线。该研究为钢琴弹奏教育服务型机器人教学平台中的手指触键运动曲线自适应判别系统的建立提供理论支持。 |

| Aiming at the establishment of a complete description of the adaptive motion curve of finger touching keys, a measurement method based on a Leap motion 3D sensor is proposed. According to capturing characteristics of the measurement method, firstly finger touch kinematics model is established before coordinate system is aligned step by step. Then the motion capture and the selection of motion feature points are carried out. The deviation angle is first introduced to transform the finger motion model from two dimensional space to three dimensional space. Finally, different fitting models are used to process the motion data of piano finger with 95% confidence bounds, and an adaptive function is established to describe the motion characteristics of finger playing. The adaptive function proves that the calibration of human hand fitting with different lengths can provide correct initial posture for the robot, which provides theoretical support for the adaptive identification system of finger touch motion curve in the teaching platform of piano playing education service robot. |
