| 摘 要： | 提出一种新的能对非均匀性校正效果进行定量计算的评估测度“校正率”,并进行了实验验证.校正率以时域噪声为参考标准来衡量图像非均匀特性,不仅可以反映图像显示效果,还可以反映图像测温精度.该方法可用于IRFPA系统的性能评价和非均匀性校正方法校正效果评价,对非均匀性校正的研究具有重要意义.

| Abstract: | A new evaluation method,Correction-Rate,was proposed,which can quantitively compute the effect of NUC,and some experiments were performed to verify its advantages.Correction-Rate uses the temporal noise as a reference standard to evaluate NU of the infrared images.It can not only reflect the display effect,but also the temperature-measuring precision.This measurement can be used in comparison of the performances of IRFPA system and evaluation of the effects of NUC methods.It is very meaningful for the further research of NUC. |
