人体重心动态测试系统的研究

Research on Dynamic Testing System of Gravity Center of Human Body

人体重心是人体环节惯性参数中能够反映人体形态结构和质量分布特征的基本参数之一,可以为体育运动、医疗康复等领域提供参考依据。为此,介绍了人体重心测试系统原理,研制开发了四支点二维重心检测平台,并编制了人体重心测试系统软件,最后分别通过爱捷录像解析系统和人体重心测试系统对人体重心检测,结果表明人体重心测试系统精度较高。

The gravity center of human body is one of the basic segnaent inertia parameters reflecting the structure of configuration and character of mass distribution of human body, which can offer references in the medical rehabilitation and the sports activity. In this paper, the testing theory is discussed firstly and the coordinate equations of the gravity center are deduced according to the moment balance theory. Then design a new four- fulcrum testing platform and the software is developed. In the end, the gravity center tested by the testing system is compared with the Engine Video Analysis Performance System and the results prove that the accuracy of the testing system is higher than of the Engine Video Analysis Performance System.
