基于VRML的手语合成系统中人体模型的运动实现

摘要

Human Modelling is the premise of sign language synthesis system. Adopting VRML-based 3D body model can improve its performance, and can lay a good foundation for sign language synthesis system. In the design of 3D body model based on VRML, we analyse the theory of change control and the affine transformation approach of body model. By using wireframe model we realise 3D body modelling. By using affine transformation we realise arm controlled movement of body model. Experimental results show that this method is effective and feasible.%人体建模技术是实现手语合成系统的前提,采用VRML( Virtual Reality Modeling Language)三维人体建模技术可以提高人体建模的性能,为手语合成系统打下良好的基础.在基于VRML三维人体模型的设计中,分析了人体模型的控制变化原理及仿射变换方法；采用线框模型实现了三维人体模型的建立,运用仿射变换方法实现人体模型的手臂控制运动.实验结果证明该方法可行有效.
