摘　　要：文章在分析了主流的Laplacian金字塔多分辨图像融合算法处理特点的基础上,介绍了基于FPGA的实时实现方法,给出了滤波、插值、延时、融合等算法模块的参数化设计方案及其并行处理流水线的细分和优化技术,分析了各个模块的资源占用情况,可以在单片X ilinxV4SX35 FPGA上实现双通道720×576×10bit图像的3层Laplacian金字塔算法融合处理。实验结果显示,采用该方法设计的融合系统融合效果良好,处理延迟小,可以实现25 f/s的实时融合处理。After analyzing the features of mainstream Laplacian pyramid multi-resolution image fusion algorithm, its implementation method based on FPGA of Laplacian pyramid multi-resolution is illustrated, including the parameterized design method of such modules as filter,interpolation, delay ,fusion, etc. The subdivision and optimization methods of the parallel processing pipelines in such modules are also given in details, which ensure the dual-channel image fusion implement in one Xilinx V4SX35 FPGA with the image size of 720 × 576 × 10bit by using 3-layer Laplacian pyramid algorithm. The experiment results show the perfect fusion effect and low processing delay of such system and it can reach the image fusion rate of 25 frames per second.
