摘　　要：在立体视觉的技术路线、建模与仿真方法和硬件实现三个方面开展研究。在技术路线方面,研究了人眼立体成像的基本原理、论述了平面图像产生立体效果的生成要素、介绍了立体视觉的实现步骤和实现方法;在建模与仿真方面,研究了基于Vega Prime的双通道立体建模与仿真成像方案,从建模的内容、模型工具的取舍、仿真驱动和成像输出等方面进行了研究。在硬件方面,采用双投影机叠加的被动式投影系统生成立体视觉图像,结合立体眼镜实现了二维平面上的立体效果输出。实践应用证明,该方法能够极大地增强视景仿真的沉浸感和逼真度,较好地满足各类高沉浸感系统的可视化要求。Three questions among stereo vision technology roadmap,modeling and simulation methods and hardware achievements were studied.In terms of technical route,the basic principle of the three-dimensional(3D) imaging of the human eye was researched,and the plane images of 3D effect of generated elements were discussed,and steps and implementation of stereo vision were introduced.In terms of modeling and simulation,a scheme based on Vega Prime with dual-channel 3D modeling and simulation imaging program were researched,and the modeling,the content of modeling,the choice of modeling tools,the simulation-driven and imaging output were researched.On the hardware side,the superposition of two-projector passive projection system was used to generate 3D visual images,and combined with stereoscopic glasses,the 3D effect on the output in the two-dimensional plane was achieved.Applications show that the method can greatly enhance the visual simulation,which meets the requirements of various types of high-immersion system visualization.
