摘要

用于全景成像的传统反射镜通常捕获圆形图像。由于这些图像很难从视觉上解释,它们通常被重新映射成一个矩形图像,其中一个轴表示方位角,另一个轴表示高程。本文描述了一类执行捕获和重新映射的镜像,从而消除了对计算资源的需求。它们在方位角和仰角上提供统一的分辨率,并且可以设计成充分利用相机的成像表面。

A New Class of Mirrors for Wide-Angle Imaging
Conventional mirrors for panoramic imaging usually capture circular images. As these images are difficult to interpret visually, they are often remapped digitally into a rectangular image in which one axis represents azimuth and the other elevation. This paper describes a class of mirrors that perform the capture as well as the remapping, thus eliminating the need for computational resources. They provide uniform resolution in azimuth and elevation, and can be designed to make full use of a camera's imaging surface.
