| 摘 要： | 介绍了红外图像非均匀性校正的基本方法，并用基于黑体多点线性校正算法对128×128的红外焦平面阵列进行了图像校正，获得了较好的结果.多点线性校正的精度与定标点的选择和其数量有关，所以在得到探测器响应曲线的基础上，对这两个因素的选择进行了分析，并用实际的校正结果对这两个因素对校正精度的影响进行了讨论.结果表明，与理论分析符合的很好.

| Abstract: | Some general methods for nonuniformity correction of infrared focal plane array (IRFPA) were discussed in the article. Multi-point linear algorithm (MPLA) based on black body was used to correct some images of IRFPA with size of 128×128 and the results were rather good. Method for the selection and determining of the number of the used points were analyzed with knowledge of the response curves of the detector because the performance of MPLA was related to these two factors. And the influence of them was also researched practically, which showed the perfect reconciliation with former analysis. |
