A FPGA-based infrared image pre-processing module is introduced.The module uses the pipeline to achieve the two-point nonuniformity correction,one-point nonuniformity correction,and pixel displacement correction.Microblaze and MPMC IP core are embedded in the module.The interface between human and machine is also added.Coefficient of one-point nonuniformity correction can be update in real time.The module can received infrared data in a certain format,and output it in the same format.It can be easily tailored to adapt to a certain infrared system.
