摘　　要：为充分发挥沉浸式训练对提高体育水平的促进作用,设计基于虚拟现实技术的三维体育辅助训练系统。在SPU处理模块控制系统整体运行的基础上,使用虚拟现实模块的输入输出单元,获取用户输入的操作命令并反馈给三维建模单元,该单元依据视频传感器与3D体感摄像机Kinect V2采集的体育运动员训练过程视频和关节位置数据,生成相应的3D模型,通过场景渲染单元完成不同场景的逼真还原,构成体育运动员训练的虚拟世界,为用户提供体育动作虚实对比、体育动作编辑等功能。实验结果表明:该系统能为运动员提供生动、逼真的训练环境;系统的实际应用能够显著提升运动员不同体育活动的成绩,辅助训练效果较为理想。In order to give full play to the promotion effect of immersion training on improving sports level,a three-dimensional sports auxiliary training system based on virtual reality technology is designed.On the basis of the overall operation of the control system of the SPU processing module,the input and output unit of the virtual reality module is used to obtain the operation commands input by the user and feed them back to the 3D modeling unit.The video and joint position data of the training process are used to generate the corresponding 3D model,and the realistic restoration of different scenes is completed through the scene rendering unit,which constitutes a virtual world for sports athlete training.The auxiliary training unit of the auxiliary training module provides users with sports action comparison,sports action editing and other functions,and the results generated by the input and output units are presented to the user to realize three-dimensional sports auxiliary training.The experimental results show that the system can provide athletes with a vivid and realistic training environment,and the 3D modeling effect is excellent;the practical application of the system can significantly improve the performance of athletes in different sports activities,and the effect of auxiliary training is ideal.
