| 摘 要： | 提出了一种基于场景运动分析的红外焦平面阵列成像的非均匀性校正算法,通过利用各探测器单元的输出在时间轴上形成的特征进行图像序列的块匹配,以获得各探测器元的相对响应关系,完成红外图像的非均匀性校正.该算法不仅能适应非均匀性随时间和环境的变化而发生缓慢变化的情况,而且对普通基于场景分析校正算法中形成的校正虚像也有很好的抑制作用.

| Abstract: | A new IRFPA nonuniformity correction algorithm is developed, based on the scene moving analysis. The correction procedure is to find the relationship between every two detectors using block matching of image sequence, and the matching information comes from the character of detectors' output signal along the time axis. The algorithm can not only adapt to the slow change of nonuniformity with time and with external conditions, but also eliminate the ghost that always apears in normal sence-based NUC analysis. The simulation results and the error analysis are also given. |
