This paper presents a panoramic stereo imaging system which uses a single camera coaxially combined with a fisheye lens and a convex mirror. It provides the design methodology, trade analysis, and experimental results using commercially available components. The trade study shows the design equations and the various tradeoffs that must be made during design. The system's novelty is that it provides stereo vision over a full 360-degree horizontal field-of-view (FOV). Meanwhile, the entire vertical FOV is enlarged compared to the existing systems. The system is calibrated with a computational model that can accommodate the non-single viewpoint imaging cases to conduct 3D reconstruction in Euclidean space.
本文介绍了一种全景立体成像系统，该系统使用单个相机与鱼眼镜头和凸面镜同轴组合。它提供了使用商用组件的设计方法、权衡分析和实验结果。权衡研究展示了设计方程以及设计过程中必须做出的各种权衡。该系统的新颖之处在于它能在360度全水平视野（FOV）上提供立体视觉。同时，与现有系统相比，整个垂直视野得到了扩大。该系统通过一个能够适应非单视点成像情况的计算模型进行校准，以便在欧几里得空间中进行三维重建。
