动作仿真技术在体育运动训练领域的应用研究

The Application of Motion Simulationtechnology in Sports Training Field

阐述了高速摄影、动作捕捉、人体运动仿真技术的原理和应用方法,解决了运动人体肌肉动态收缩无法测量的问题,同时也指出了运动人体建模的发展方向:(1)新的算法理论会逐步融入人体运动建模中,同时多维度的数据采集和输入将会使人体运动仿真结果更全面更精准,应用价值更大。(2)人体的运动是一个典型的闭环控制反馈系统,人体每一个精准的运动动作都在输出与控制的基础上完成,因此系统与控制理论在研究人体肌肉激励方面将会有新的突破。(3)人具有主观能动性,无论是运动捕捉系统采集人体的运动学数据还是动作仿真系统仿真分析人体骨骼肌肉受力状况,都是建立在力学和运动生理学基础之上的,人的主观特性会因为某时刻的心理特点而影响神经和肌肉特性,因此把人的心理评价数据融入人体建模中是一个人体建模应该考虑的问题。

This paper expounds the high-speed photography, motion capture, human motion simulation technolo-gy principle and application method of solving the motion human body muscle contraction can＇t dynamic mea-surement problem, at the same time, it points out the development direction of movement of human body model-ing：（1）The new algorithm theory will be gradually integrated into human motion modeling, and the data acquisi-tion and input of multi-dimension will be the result of human motion simulation more comprehensive and accu-rate, and the application value is greater.（2）The movement of the human body is a typical closed-loop feedbackcontrol system, the human body each precise movements is done on the basis of the output and control, so the sys-tem and control theory in the study to the muscles will have new breakthrough in incentives.（3）People have sub-jective initiative, in both motion capture system of the human body kinematics data points are analysis of humanskeletal muscle force action simulation system, is built on the basis of mechanics and exercise physiology, andpeople＇s subjective characteristics for some time psychological characteristics and the influence of nerve andmuscle characteristics, and therefore the psychological evaluation data melts into the human body modeling is ahuman body modeling to consider problems step by step.
