摘　　要：图像匹配是图像处理的一个重要分支,其算法运算量大。针对图像互相关匹配算法具有较强的并行特性,提出空间分块技术对图像进行分块以及算法进行任务均衡分解,并将分割的图像数据通过FPGA生成的四块双口RAM空间进行数据存储并传输给多DSP进行图像NCCF值计算,实现快速图像匹配。实验证明该系统实现方案可行,具有较强的实际应用效果。Image matching is an important branch of image processing,the computation of its algorithm is large.For image correlation matching algorithm has a strong parallel nature,the paper presents Block Of Space Technology for blocking image and decomposing task algorithm balancly.To achieve fast image matching,the segmented image data is storaged and sent to Multi-DSP for image NCCF calculation on four pairs of port RAM space which is generated by FPGA.The experimental result show that the system implementation is feasible,it has a strong practical application effect.
