【摘要】 在仿真、虚拟现实及娱乐领域,高分辨率的视频图像显示有着广泛的需求。提出基于多投影的大屏幕视频显示系统,采用基于计算机集群的层次化系统结构,并基于Master-Slave模型分布管理视频数据。基于事件驱动的同步模型实现了多个进程、线程间的同步解码、播放。结合BH-TDAPI实现了视频图像在多投影的大屏幕环境下的无缝拼接显示。实验表明,该系统具有良好的可扩展性与较高的性价比。更多还原

【Abstract】 High resolution video displaying is widely needed in the area of simulation, virtual reality and entertainments. The paper proposed a multiple projectors based video display system, which is constructed by a hierarchical architecture and manages the distributed video data by Master-Slave model. With the event-based driven model, the proposed system synchronizes the nodes and windows decoding, rendering and displaying. Combining with BH-TDAPI, the system can project seamless tiled images on large scale screens and get seamless, tiled, wider images. Experiments demonstrate the system’s great scalability and high cost performance.更多还原
