基于分布式绘制的大幅面立体像对快速浏览技术

针对当前影像数据存储格式不能适应海量影像数据快速访问的情况,研究设计了大幅面立体像对的逻辑四叉树存储格式,并通过立体像对的逻辑四叉树剖分算法把普通格式的立体像对格式快速转换成逻辑四叉树存储格式。由于单机显示无法满足大幅面立体像对的高分辨率、高沉浸感的显示,因此系统研究了大幅面立体像对快速浏览的分布式结构,包括硬件选择、分布式策略和通信方式等方面。由于当前分布式网络不足以支持大规模数据的实时传输,根据帧相关性原理,研究提出了大幅面立体像对的分布式缓冲机制。最后通过实验证明该方法能够实现大幅面立体像对的实时浏览。

Fast Rendering for Great Width Stereo Image Pair Based on Distributed Rendering

The current image data format cannot fit the fast access of the massive image data,so the logistic quad-tree structure has been designed for the large scale stereo image pair,and the ordinary form of stereo image pair can be fast changed into logistic quad-tree structure ones through the split method of the logistic quad-tree structure.The single machine display cannot meet the high resolution and high immersion display of the large scale stereo image pair,so the distributed structure has been studied to the fast browsing of the large scale stereo image pair,including hardware choice,distributed strategy,communications method,and so on.Because the current distributed network is insufficient to support the real-time transmission of the large-scale data,the data management mechanism has been proposed for the large scale stereo image pair according to the frame relevant principle,including distributed cache mechanism and fast access algorithm.The experiment proves that the application above technology to the fast rendering for the great width stereo image pair has realized real-time roams in the large screen stereo display.
