aim to the large amounts of image-processing data and difficultly realizing real-time correction during nonuniformity correction of infrared focal plane arrays (IRFPA)
a kind of multi-point real-time nonuniformity correction based on system on programmable chip (SOPC) in Altera company is proposed. Hard software can speed up real-time nonuniformity correction of IRFPA through creating custom instructions for NiosII embedded processor. The experimental results show the correction method is simple and flexible and the image is clear. It can satisfy the requirements of real-time nonuniformity correction of IRFPA.
