摘要
为提高红外焦平面阵列盲元的定位精度,分析了盲元的产生机理,指出了探测器所处环境温度对探测元的探测能力以及焦平面阵列的盲元数量和位置分布的影响,提出了一种考虑环境温度差异的红外焦平面阵列盲元检测算法,精确定位了不同温度范围内的盲元位置。实验结果表明,该算法可将随环境温度改变而改变的盲元位置信息准确检测出来。
In order to improve the positioning accuracy of blind pixels in Infrared Ray Focus Plane Array (IRFPA), the principle of blind pixels appearance was analyzed in this paper. The environment temperature affected the detection capability of effective pixels, quantity and position of blind pixels. Therefore, the algorithm of blind pixels detection for IRFPA considering different environment temperature was proposed. The purpose of the algorithm was to position blind pixels and get quantity of blind pixels in different temperature ranges accurately. The results of experiment indicate that the algorithm can detect the changes of the positions of blind pixels with the environment temperature.
