多通道投影显示系统同步算法研究
Research of Synchronization Algorithms in the Multi-channel Tiled Display System
摘要
Abstract
In order to solve the problem of frame images＇ non-synchronization due to the imbalance overload of different rendering nodes, two synchronization algorithms were proposed which were the feedback verification and dead reckoning algorithm （FVDR） and texture image cutting algorithm （TICA）. Feedback verification, maximum related waiting time and dead reckoning mechanisms were used to achieve synchronization for the FVDR algorithm. And the TICA algorithm firstly got a large texture image, and then cut the im- age and assigned to every visual client. The derivation of the two algorithms and their program implementations based on Visual C ＋ ＋ and OpenGL were given in a three-channel tiled display system. Contrast experimental results showed that both of the two proposed al- gorithms could achieve better synchronal effect on improving visual images＇ timeliness and consistency.关键词
