基于PC架构的高性能分布式拼接技术研究与应用

High-Performance Distributed Mosaics Technology Research and Application Based on PC Architecture

随着数字化信息技术的不断发展,大屏幕的作用越加重要,它的角色从传统的信息展示逐渐向实时监控转变,尤其是能源、交通对实时监控要求较高的行业应用越来越广泛。支撑大屏幕运行的重要技术是图像拼接,图像拼接技术的优劣直接决定了大屏幕技术的应用水平,图像拼接是可视化技术领域一项热门技术,将不同视频源视频图像进行叠加、拆分等,形成一幅无缝隙高分辨率的图像。结合分布式技术和图像拼接技术的优势,提出基于PC架构的分布式拼接系统,实现视频图像的分布式接入及展示,针对分布式拼接技术中显示同步、图像拉伸、视频流定位技术进行深入探讨,提出简单快捷的算法,并实现了具体应用。

With the development of digital information technology,large screen plays more and more important role while changing gradually from traditional information display to the real-time monitoring.It particularly more widely applied in energy and transport industry which require a higher real-time monitoring.Image mosaics is the important supportive technology in large screen,so it directly determines the level of application of lorge screen technology.The image mosaics is a popular art visualization technology,which processing the video images from different sources by overlaying and splitting etc.,forming a seamless high-resolution images.This paper combines the advantages of distributed technology and image mosaics technology,proposing distributed image mosaics systems based on PC architecture for video image distributed access and display.This paper deeply study the display synchronization,image stretching and streaming video targeting of distributed mosaics technology,also make quick and easy algorithm and implements specific application.
