| 摘 要： | 在分析红外焦平面非均匀产生原因的基础上,阐述了两点校正法的原理.由于各探测器与相邻单元的增益比率具有相关性的特点,利用相邻单元的增益比率,迭代实现比率和偏差的校正,从而减小其图像的非均匀性.仿真计算验证算法能有效地消除图像非均匀性噪声,增强图像的视觉效果.

| Abstract: | The cause for the nonuniformity is analyzed of infrared focal plane array (IRFPA).The principle of two-point correction is studied.As there exists correlation gain ratio between detector and its adjacent cell,we take use of the gain ratio of adjacent cell to realize gain and offset correction by iteration,and to reduce image nonuniformity gradually.It is verified by simulation that the infrared image is suppressed effectively,and the visual quality of the infrared image is improved greatly. |
