Real-time panorama video system using networked multiple cameras

Although panorama creation has been studied extensively, previous works still have limitations because they depend on customized hardware or post processing, resulting in high production cost and complexity. We propose and implement real-time panorama video system by using off-the-shelf embedded boards and camera modules. For real-time, we developed the performance improving methods such as reducing the homography computation load and employing multi thread structure. We conducted a series of experiments to investigate how different blending combinations and the number of threads affect the performance and image quality. We also analyzed the time consumption of threads and stitching steps. (C) 2015 Elsevier B.V. All rights reserved.
