摘　　要： 虚拟角色运动的实时控制是虚拟健身运动仿真中的难点。提出一种基于实时数据驱动的虚拟角色跑步控制方法,建立基于传感器的实时数据获取模型,分析人体跑步运动规律,建立跑步运动的数学模型,运用基于旋转角度的方法求解人体运动链上各个关节运动,采用L-?插帧法对关键帧之间的过渡帧进行运动插值运算,在Visual C++环境下结合EONSDK实现了虚拟人跑步运动的实时控制。测试效果表明:该控制方法能很好的满足健身运动仿真的需要。 The real-time control of virtual character behavior is a challenge in simulating virtual exercise. A kind of virtual character running behavior control method based on real-time data-driven was proposed, the real-time data acquisition with the help of sensor was expounded, the time-series law of human body running was analyzed, the human body posture mathematics expression was modeled, and a limb movement parts and rotation degrees of freedom computing model was proposed. By use of rotation angle method, the space and time relationship of each part of human movement chains was established and the movement process frame when moving was arithmetized by use of L-? inserted frame. By combining Eon SDK, the real-time control of character running behavior was realized in Visual C++. It is proved that this control method can meet the needs of sports simulation.
