| 摘 要： | 介绍了基于FPGA的红外图像处理与实时显示系统的工作原理。针对传统的红外焦平面阵列(IRFPA)非均匀性校正算法的不足，提出了对采用神经元法和两点线性法校正其非均匀性算法的改进，重点介绍了两点线性法的软硬件实现方式，该算法在Spartan系列FPGA上实现并获得成功。

| Abstract: | In this paper, the operating principle of an infrared video processing and displaying system based on FPGA is presented in detail. Because of the disadvantages of the traditional non-uniformity correction method ,we improve the correction altorithm using neural networks method and two-point linear method. And the software and hardware structure of two-point linear correction are described. The algorithm is used successfullu in spartan series FPGA. |
