摘　　要：分析了导致红外成像系统非均匀性的机理,介绍了红外焦平面阵列非均匀性校正的基本方法。采用两点校正和积分时间校正相结合的方法,利用TMS320VC5509A DSP完成了对红外图像的非均匀性实时校正。实验结果表明,本系统具有实时性好,实用性强的特点,能够满足红外焦平面成像系统的要求。Several nonuniformity correetion（NUC） methods are described on the basis of analyzing the mechanism of the IRFPA＇s nonuniformity. Making use of powerful computational capability and good programmability of TMS320VC5509A DSP hardware, two-point correction method and integration time correction method is therefore proposed to do automatically the real- time correction of infrared image. Experimental result verifies that the high performance of the infrared image nonuniformity real- time correction system based on DSP is obtained.
