Wide field of view (FOV) and high-resolution image acquisition is highly desirable in many vision-based applications. Several systems have reported the use of reflections off mirror pyramids to capture high-resolution, single-viewpoint, and wide-FOV images. Using a dual mirror pyramid (DMP) panoramic camera as an example, in this paper, we examine how the pyramid geometry, and the selection and placement of imager clusters can be optimized to maximize the overall panoramic FOV, sensor utilization efficiency, and image uniformity. The analysis can be generalized and applied to other pyramid-based designs.
在许多基于视觉的应用中，大视场（FOV）和高分辨率图像采集是非常理想的。已有多个系统报道了利用镜锥反射来捕获高分辨率、单视点和宽视场图像。以双镜锥（DMP）全景相机为例，在本文中，我们研究如何优化锥面几何形状以及成像器集群的选择和放置，以最大化整体全景视场、传感器利用效率和图像均匀性。该分析可以推广并应用于其他基于镜锥的设计。
