摘　　要：AR(AugmentedReality增强现实)系统运行时包含很多图形、图像的相关计算任务,要求系统实时完成,这个问题在基于PC的AR系统中更为突出.为了提高IP(ImageProcessing图像处理)计算的实时性,提出了一种可行的并行解决方案.硬件上采用基于SMP(SymmetricMultipleProcessor对称多处理器)的Cluster结构,算法上运用并行图像算法.在Windows操作系统下用多线程和MPI(MessagePassingInterface消息传递接口)技术,设计了并行图像算例实验,并对这两种方法进行了综合比较.Augmented reality(AR) systems require a large amount of real time computation to modeling graphics and image processing. The problem has long challenged the designers, especially in PC based AR systems. In order to improve the speed of image processing and modeling, Cluster frame based on SMP PC and parallel image processing algorithms are adopted. Two parallel algorithms have been designed and tested on sample images. Comparison result of the suggested algorithms is reported.
