摘　　要：针对红外焦平面阵列非均匀性多点校正过程中涉及的数据量大,难于实现实时校正的特点,提出了利用TMS320DM642 DSP硬件对红外焦平面阵列进行多点实时校正。利用DSP的硬件乘法器和加法器能够高速有效地实现红外焦平面阵列的非均匀性校正。实验结果表明利用DSP实现红外焦平面阵列实时非均匀性校正方法简单灵活,图像效果理想,能够很好地满足红外焦平面阵列成像系统实时性能的要求。Aiming at the large amounts of image-processing data and di^ficultly in realizing real-time correction during nonuniformity correction of infrared focal plane arrays （IRFPA）, a kind of hardware correction with TMS320DM642 DSP is proposed. The nonuniformity of IRFPA can be realized effectively and speedly by using hardware multiplier and adder. 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.
