数据平滑对运动学数据中极值的影响——以数字低通滤波法为例

Effect of Data Smooth on Extremum of Kinematics in Sports Analyses

在进行人体运动动作的运动学影象分析中 ,数据平滑是必不可少的数据处理方法。一些研究对平滑程度的选取随意性较大。本研究通过对实验数据进行不同程度的平滑结果的比较 ,考察其对运动学参数极值的影响程度 ,得到相当明显的结论。希望能引起重视 。

In kinematic analyses of sports performances,the smooth method is necessary to reduce the errors. In this paper,the comparison in different smooth degree has been examined by an experiment.It is evident that the effect of smooth on the extremum can not be ignored.
