摘 要: 目的编制运动序列解析程序,并通过该程序得到有关运动过程中的一些重要参数。方法通过理论分析把人体简化为一个由15个刚体组成的多刚体系统;使用高速摄影机拍摄了运动员在最后用力阶段标枪投掷的实际过程。结果得到了运动员在最后用力阶段的序列图像,并生成人体运动棍棒图,给出了各关节的运动参数(包括:速度、加速度以及重心位置等)。结论该程序基本实现了预定目标,可使用其进行标枪投掷运动的解析,获得标枪运动员的重要投掷参数。 Objective Analyzing program was designed to get some important parameters in Javelin throwing process. Methods The human body was simplified as a multi rigid body system composed of fifteen rigid bodies; the Javelin throwing process of the athlete was photographed by high-speed photography. Results A series of images in the final thrust phase were obtained, and stick figure of human body and the parameters of joints were given (including velocity, accelerator, and the position of center mass, etc.). Conclusions By this program, the prescribed purpose was realized, and the throwing parameters of Javelin thrower's joints were obtained through the analyzing.
