Achieving High-Resolution Video Using Scalable Capture, Processing, and Display

Overview

New video applications are becoming possible with the advent of several enabling technologies: multicamera capture, increased PC bus bandwidth, multicore processors, and advanced graphics cards. This paper presents a commercially-available multicamera system and a software architecture that, coupled with industry trends, create a situation in which video capture, processing, and display are all increasingly scalable in the number of video streams. Leveraging this end-to-end scalability, the authors introduce a novel method of generating high-resolution, panoramic video. While traditional point-based mosaicking requires significant image overlap, authors gain significant advantage by calibrating using shared observations of lines to constrain the placement of images.
