虚拟环境内部的数据变换和融合研究

虚拟环境（ＶＥ）是一个融合了多维信息数据以产生沉浸感，投入感的仿真环境，为交互ＶＥ中的虚拟对象，需经过一系旬的几何变换，研究了ＶＥ中各种坐标系的几何变换过程，重点探讨了手空间，立体视觉与虚拟空间的数据融合，保证了人机交互的协调性，而且，就上述理论环境，给出了具体的实例，验证了ＶＥ内部的数据融合了关系。

Research of Data Transformation and Fusion in Virtual Environment

Virtual Environment (VE) is a simulation environment,which fuses much information of cyber soace to make the effect of immersion and interaction. To interact the virtual objects in VE , a series of geometric transformation should be offered .This paper studies the geometric transformation procedure,which exists in the coordinate system of VE. Especially, the research of fusing the information of the hand space and stereoscopic vision in virtual space is given.It assures the harmony of the interaction between human and the computer.
