【摘要】 人类运动与人体健康息息相关,一直以来受到人们的广泛关注,随着运动生物力学、人体测量学的发展,人们对人体运动的研究日益深入。本文以运动生物力学理论为基础,对人体运动参数的测量和分析方法进行了研究,主要目的在于探索运动生物力学参数之间的关系,通过运动生物力学参数的测量、分析揭示人体运动的规律,在人体姿态识别、体育训练等方面提供理论指导。在对人体结构及人体运动的特点进行了介绍和总结的基础上,为了便于人体运动研究,建立了人体运动的棒状模型及便于分析计算的人体坐标系。通过对常用人体运动参数测量方法的分析,提出了利用加速度参数进行运动测量和分析的方法。应用加速度传感器实现了对肢体运动的测量,并利用加速度参数与速度、位移等参数之间的数学关系实现了对其它运动参数的求解,从而对人体运动的姿态、动作轨迹等进行分析。自行研制了运动采集系统,系统分为信号采集单元与数据处理单元两个部分,以ARM7、三轴加速度计ADXL330为核心,可实现最多5个传感器网络节点的信息采集及数据分析。在对系统完成性能测试的基础上进行了运动测量的实验,并将其应用到电脑游戏的控制中进行可靠性的测试,实验结果验证了利用运动信息采集系统对人体运动信息进行采集和分析的方法是可行的。利用加速度参数对人体简单运动进行分析的方法方便可行,但在复杂运动的分析中,则需要更多的信息进行综合分析。因此,对于人体运动的研究,应综合多种方法,尽可能获取更多的信息,以使得人体运动分析更加科学、合理。更多还原

【Abstract】 Human has always paid broad attention to body motion relating close to human health. With the development of motion biomechanics and anthropometry, people have increasingly deeply studied human body motion. The paper focuses on the measurement of body motion parameters and analysis method of body motion based on the theory of motion biomechanics. The contents involve the study on the relationship between parameters of motion biomechanics, the analysis of the law of body motion by measuring motion biomechanics parameters to provide theoretical guidance for recognition of human gesture, physical training, and so on.Human structure and characteristics of body motion are analyzed and summarized, on the basis of which rod model and coordinate system of human body are built to provide convenience for the study of body motion. The method of measuring body motion with acceleration sensor is presented with the analysis of common measurement method of body motion parameters. The measurement of extremity is performed by acceleration sensor; other motion parameters are solved by the mathematical relationship between acceleration parameter and velocity, displacement, etc.. Thereby, motion gesture and action trace of human body can be analyzed.A system which consists of signal collection unit and data processing unit is developed to complete collection and data analysis from the motion information at most 5 sensor network nodes using ARM7 and ADXL330. The experiments of motion measurement are done on the basis of performing the testing of system performance, and the system is applied in computer game for the reliability testing. The results show that collecting and analyzing motion information of human body by the system is a feasible method.The analysis of simple body motion using acceleration parameter is a convenient and feasible method. But more information is required to be analyzed synthetically in the complex motion. Therefore, it is necessary for the study of body motion to synthesize a variety of methods and obtain as much information as possible, which makes the analysis of body motion more scientific and rational.更多还原
