中文摘要：

现有传统的建模软件可以进行三维建模,但是这种模型缺乏实时交互性能,即模型动作是预先设定好的,用户不能够实时的和模型进行交互。针对这一问题,提出了一种改进的虚拟三维模型重建的方法,采用插帧和顶点变换等算法,有效地实现了用户和虚拟三维模型间的实时交互,并以人手骨骼结构为例进行建模,实现了各关节和真实人手具有相似的自由度。实验结果表明,虚拟人手系统增强了虚拟人手的真实感和交互性,实现了虚拟人手的实时控制。

英文摘要：

The traditional modeling tools can be used for 3D modeling, but the model is lack of real-time interactive performance, the model action are predetermined, user can not change model action in realtime. An improved virtual 3d model reconstruction method is proposed, using the algorithm of frame interpolation and vertex transformation, through which the real-time interactive performance can be well achieved. Virtual hands are constructed with the references to human hand bone structure, and the joints have similar degrees of freedom with real human hands. The experimental results show that, the virtual hand system enhances the realism and interactive performance, and the virtual kinematics simulation and real time control are well achieved.
