摘　　要：依据数字信号处理理论和当前影像分析中的误差特点,提出了改进数据中的随机误差处理的方法;并在此基础上建立了检验影像分析中数据精度的方法。通过实例说明方法是可行的。本研究成果可做为正在推行的运动生物力学影像分析研究规范化内容之一,专用程序可方便地移植到影像分析软件。A new film data processing method for improving stochastic errors was introduced and based on this a different method for examining data accuracy in film analysis was developed with the theory of numerical signal processing and the characteristics of film errors. The two methods were tested and proved workable through analysis of actual examples. The processing programme of the methods can be easily transplanted into any film analysis software.
