摘　　要：由于材料、工艺等原因,红外焦平面阵列(IRFPA)各探测元存在响应不一致问题,导致红外图像的非均匀性。非均匀性校正(NUC)是红外成像仪图像处理系统的重要环节。本文结合空间相机的应用重点分析了基于定标的两点校正法和基于场景的自适应神经网络法,并通过仿真图像验证了神经网络算法的校正效果。Due to the the material and manufacturing technology of the IRFPA, every detector＇ s responsivity is different, which result in non - uniformity of IR images. Thus non - uniformity correction（NUC） is very important to the application of airborne infrared imag- ers. Based on the analysis of the application of space infrared camera, this study focus on the two - point algorithm based on calibration and the adaptive algorithm based on neural network. The algorithm of NN is tested by simulated image.
