| 摘 要： | 针对IRFPA非线性物理系统的特征,提出一种基于多项式拟合的非均匀性校正算法,并给出了硬件实现电路。该算法是在最小二乘意义上的多项式曲线拟合,实验结果表明,其校正效果明显优于分段线性校正算法。

| Abstract: | Aiming at the nonlinear physical system characteristic in infrared focal p lane arrays, a new polynomial fitting based on nonuniformity correction algorithm and a hardware imp lement circuitwere p roposed. The algorithm is polynomial curve fitting based on least square app roximation. The experimental result shows its performance is more effect than that of the piecewise linear algorithm. |
