摘　　要：提出在IRFPA非均匀性校正中使用埃尔米特插值方法,与其他传统方法相比较具有运算量小,修正效果好,易于实现等优点。在既有乘性噪声,又有较强加性噪声的情况下,仿真效果优于拉格朗日分段线性插值算法,是一种新的非均匀性校正算法。Hermite interpolation algorithm is described in IRFPA nonuniformity correction. Compare with other traditional algorithm, it has advantages of less calculation, higher correction precision and easy implement by hardware. Under multiply and strong noise conditions, Hermite interpolation simulation is better than that of multi-section interpolation algorithm.
