船舶操纵模拟器立体视景系统理论、方法和实现的研究

Theroy,method and realization of stereo visual system of shiphandling simulator

在船舶操纵模拟器中,视景系统的立体显示为场景中物体的空间关系提供重要的视觉信息,并大大地增强了三维场景的真实感。分析了立体显示方法的原理,介绍了多通道立体显示系统所需的设备及环境,提出了基于Vega的船舶操纵模拟器的立体显示视景系统结构框架,阐述了Vega中场景初始化的方法及立体显示参数的设置,并实现了基于Vega的船舶操纵模拟器视景系统的立体显示,提高了船舶操纵模拟器视景系统的逼真度。

In the navigational simulator, a stereo display can provide important visual information for the spacial relationship among the objects and enhance the reality of 3D virtual scene. The theory of stereo display was analyzed, and the equipment and environment required by multi-channel stereo visual system were introduced. The framework of stereo visual system based on Vega was presented, and the method of initializing scene and the setting of stereo display parameter in Vega were expounded. Therefore, the realization of the multi-channel stereo visual system of shiphandling simulator based on Vega could enhance the fidelity of stereo visual system.
