Algorithm of Blind Pixels Auto-searching and Compensation for IRFPA

在分析盲元响应特性的基础上 ,利用红外焦平面阵列对双参考辐射源的响应数据和相邻像元成像数据的相关性 ,提出了一种基于双参考辐射源的盲元现场自动检测和插值补偿算法 ,实现了盲元的自动检测和校正 实验结果表明 :该方法具有对盲元查找速度快、定位准确率高。

Based on the analysis to the behavior of blind pixel, an auto searching and interpolation compensation algorithm for blind pixels by using IRFPA′s imaging data of two reference radiation source and the pertinency between the adjacent pixels is advanced. Then auto searching and compensation for blind pixels of IRFPA is achieved. The experiments on real Infrared imaging sequences demonstrate that the algorithm has the advantages of apace and high veracity for blind pixels location, good correction effect and easy implementation.
