基于定标法的红外图像非均匀性校正

Calibration-Based Non-uniformity Correction in Infrared Images

采用一点和两点定标法对实际红外凝视型系统图像进行了非均匀校正,运用客观评价的方法对两者的校正效果进行了比较:一点法算法简单,但其校正结果无法满足红外系统,而两点法校正后图像的非均匀性则能很好的满足系统的要求。

The methods of one - point and two - point NUC correction are used to correct actual IRFPA images. The result of objective evaluation for two methods shows that the method of one - point NUC correction is simpler, but correction effect cannt meet practical requirment; while correction effect of two-point NUC correction can satisfy the practical requirment.
