摘　　要：基于双视点重构的立体显示原理建立虚拟3维空间到真实空间的映射关系,据此诠释前景畸变产生的原因是虚拟空间到真实空间映射关系的非线性,进而提出以改变视点设置与变形虚拟3维空间相结合的方法改变水平位差分布,实现前景立体视觉的优化,并且评估了该方法校正前景畸变的效果以及对前景和远景双影的影响,最后,提出基于动态视点更新和动态空间压缩的立体全景视觉优化策略。与美国DTI公司的3维立体显示软件TextureEyes相比,笔者据此开发的3维立体显示软件的前景畸变和双影减小明显。The mapping transformations from virtual space to real space are built according as the principle of autostereoscopic display based on bi-viewpoint restructure. And the reason for the foreground stereoscopic distortion is found out as follows： the mapping transformations from the virtual space to the real space are nonlinear. The horizontal position disparity on screen could be redistributed by means of changing the setting of the bi-viewpoint and compressing the virtual space, which is a new method brought forward in order to optimize the foreground stereoscopic vision in 3D autostereoscopic display. The effects to foreground and background bi-images as well as the degree of reducing the foreground stereoscopic distortion have been evaluated with regard to this method. Further, a strategy for optimization full-ground stereoscopic vision is introduced based on the dynamic update of the bi-viewpoint and the dynamic compression of the virtual space. Compared with American Dimension Technologies Inc.＇s 3D autostereoscopic display software（TextureEyes） , the software developed on the basis of this paper can significantly reduce the foreground stereoscopic distortion and the bi-images.
