为了解决基于关键帧的虚拟人运动动画在面对台阶行走时逼真度下降的问题，提出关键帧重载技术。分析虚拟人的平地行走模式与台阶行走模式之间的相似与差异，结合关键帧技术与反向动力学计算技术，对虚拟人台阶行走的特定关键帧进行重绘，使虚拟人具有对环境的实时反应，并进行了实验分析。实验结果表明：采用提出的基于关键帧重载技术的虚拟人运动控制方法可以提高虚拟人行走的逼真度。

Keyframe overloaded technology was proposed in order to solve the problem that it was not realistic when virtual hu-man based on keyframe system walked on the stairs. The differences and similarity of the models between virtual human’s ground walk-ing and stairs walking were analyzed. Through a combination of inverse kinematics and keyframe animation,certain keyframes were re-drawed to make the virtual human have a real-time response to the environment. The experimental results show that the method can be used to effectively improve the fidelity of the virtual walking.
