谭思欣平衡木交换腿结环跳三维虚拟动作的运动学分析

Kinematics Analysis of Tan Sixin 's Virtual Reality Movement of Change Leg Ring Leap

通过三维拍摄2013年全运会体操平衡木冠军谭思欣的比赛录像,对谭思欣交换腿结环跳动作进行三维解析,获得该技术动作系统运动学参数;利用沉浸式三维虚拟现实技术对获得的运动学数据进行动作重建,经360°旋转后观察动作的三维动画,再进行运动学分析,找出谭思欣交换腿结环跳技术动作完成的优缺点。结果显示,谭思欣的动作技术比较标准、合理。

The performance of Tan Sixin,the champion in the 2013 National Games was filmed on the spot. The change leg ring leap movement was chosen and analyzed by three-dimensional video analysis method which could get a series of kinematics parameters of the movement;make the chosen movement re-display based on the kinematics parameters by using the Virtual Reality Technology（which could output the three-dimensional video）, after 360＆#176;rotation and make kinematics analysis of the virtual reality movement. The advantages and disadvantages of the performance were found. It turned out that Tan’s movement was relatively normative and reasonable.
