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.
