Construction of hierarchical human motion model for sports biomechanics

运动生物力学层次化走立人体运动模型是以运动生物力学影像解析为基础,它能将复杂化的人机对话简单的集成在一个系统中,并且快速的以三维动画的形式展现出,直接的将影像分析结果展现在运动员及教练面前,为体育运动带来便捷服务,从运动生物力学方面进行分析,探讨三维仿真虚拟人体标准模型定义的不统一问题,分析建立层次化人体运动模型的方法。先是分类运动人体关节,之后分析人体通用模型的数据结构和定义,并分析人体运动特殊器官手、足、脊柱等定义,然后构建运动状态方程进行人体运动建模关键数据的捕获和特征分析;最后进行仿真实验,结果表明,该方法提高了人体运动分析的准确率,对运动步行、跳跃、侧手翻等人体运动的重构能力好,结果具有一定的合理性。本文分析的人体模型在人体运动生物力学特征描述上比较常用。

The hierarchical human motion model of motion biomechanics is based on the analysis of motion biomechanics images. It can simply integrate complex human-machine dialogues into a system and quickly demonstrate it in the form of three-dimensional animation. The results of image analysis are directly displayed in front of athletes and coaches, which brings convenient services to sports. From the aspect of sports biomechanics, the inconsistent definition of three-dimensional virtual human model is discussed, and the method of establishing hierarchical human movement model is analyzed. First, it classifies the movement of human joints, then analyzes the data structure and definition of the general model of the human body, and analyzes the definition of the hand, foot, and spine of the human body movement special organ, and then constructs the motion state equation to capture and analyze the key data of human motion modeling;Finally, the simulation results show that the method improves the accuracy of human motion analysis, and reconstructs the ability of human movement such as walking ,jumping, and turning. The results are good.
