对ATP冠军巡回赛成都公开赛半决赛中2名运动员托马斯·恩奎斯特和卡洛斯·莫亚的发球技术进行分析。采用三维摄像解析法获得运动员发球技术相关运动学参数，根据研究目的将动作划分为抛球举拍阶段、向后挥拍阶段、向前挥拍击球阶段，获取世界优秀男子网球运动员发球技术各阶段的相关运动学参数；利用沉浸式三维虚拟现实技术对获得的运动学数据进行重建，通过360°的旋转再现观察，以三维动画的形式进行运动学比较分析。结果显示恩奎斯特动作技术更合理、更规范，值得网球运动员借鉴。

The tennis serve technology of the two players, Thomas Enqvist and Carles Moya, in the semifinals of 2011 Chengdu Open-ATP Champions Tour were filmed and analyzed with three-dimensional video analysis.According to the purpose and need for this study and combined with the actual technical movements, the serve technology was divided into three stages as follows: throwing ball rising racket stage, backward swinging stage and forward swinging hit stage.Then, kinematic analysis for each stage is condected.Based on the data of kinematic analysis, a three-dimensional model of the human body movement, with the diagnosis of sports biomechanics, the computer realization of 3D dynamic display reproduction is established.The method can simultaneously output three-dimensional images, data and curve, through the three-dimensional image, it can be directly used to correct training plan through the visual feedback;it is vivid and accurate reproduction of the athletes'trajectory angle information by data and curves.The kinematics characters of high-quality tennis serve were presented to provide the basis for tennis training and match.
