Abstract

We report on the image formation pipeline developed to efficiently form gigapixel-scale imagery generated by the AWARE-2 multiscale camera. The AWARE-2 camera consists of 98 "microcameras" imaging through a shared spherical objective, covering a 120° x 50° field of view with approximately 40 microradian instantaneous field of view (the angular extent of a pixel). The pipeline is scalable, capable of producing imagery ranging in scope from "live" one megapixel views to full resolution gigapixel images. Architectural choices that enable trivially parallelizable algorithms for rapid image formation and on-the-fly microcamera alignment compensation are discussed.

摘要

我们报告了为有效生成由AWARE-2多尺度相机产生的十亿像素级图像而开发的图像形成流程。AWARE-2相机由98个“微型相机”组成，这些微型相机通过一个共享的球面物镜进行成像，覆盖120°×50°的视场，瞬时视场约为40微弧度（一个像素的角范围）。该流程具有可扩展性，能够生成范围从“实时”百万像素视图到全分辨率十亿像素图像的图像。文中讨论了一些架构选择，这些选择使得能够采用易于并行化的算法来进行快速图像形成和实时微型相机对准补偿。
