摘要
传统动作捕捉与分析采用机械、光学及声学方式,所占空间大,价格昂贵,操作也较为复杂。研究了基于九轴惯性传感器的人体动作捕捉系统,将惯性传感技术与人体科学相结合,在人体上抽象出17个关节点,通过这17个关节点采集人体运动数据。数据通过无线保真方式发送至计算机,在计算机上对数据进行处理,得到驱动人体模型运动的姿态数据,从而控制虚拟模型进行运动展示。这一动作捕捉系统具有经济、便利、不受场地和天气因素影响等多种优势,实现了对人体运动姿态的实时采集与分析,可以使运动训练更加科学与高效。
Traditional motion capture and analysis are conducted in mechanical, optical or acoustic modes, however theses modes occupy large space and cost with complicated operations. A human body motion capture system based on 9-axis inertial sensor was studied, the inertial sensing technique was combined with human science to abstract 17 articulation points from human body, human motion data were collected through the 17 joints while the data were sent to the computer by Wi-Fi. The data was processed on the computer to obtain the posture data that drove the model motion in order to control the virtual model to show the motion. This motion capture system has the advantages of economy, convenience with no affects from other factors such as site and weather. Due to that it is possible to realize real time acquisition and analysis of the posture as the human body is moving it can make sports training more scientific and more efficient.
