在本文中，我们提出了一个概念，用于保持一个给定的三维图像或视频的三维宽高比后，缩放的观察窗口或改变显示尺寸。水平和垂直调整大小的立体3D场景将沿z轴沿着倾斜。也就是说，感知深度将不成比例地增长，因为视差与视差因子成线性增长。本文中解释的几何模型通过导出非线性调整大小因子来解决这个问题，该非线性调整大小因子非线性地改变立体或多基线相机装备的深度相关视差，从而在任意显示器和视口大小上在第三维中保持适当的纵横比。
In this paper we present a concept for maintaining the three dimensional aspect ratio of a given 3D image or video upon resizing the viewing window or changing the display size altogether. A stereoscopic 3D scene that is resized horizontally and vertically will appear skewed along the z-axis. That is, the perceptual depth will grow aproportionally because the disparity grows linear with the resizing factor. The geometric model explained in this paper solves this problem by deriving a non-linear resize factor that non-linearly alters the depth dependent disparity of a stereo or multi-baseline camera rig, and thereby preservers proper aspect ratios in the third dimension on arbitrary displays and viewport sizes.
