摘要
设计了一种用于红外焦平面热像仪NETD参数自动测量的算法,也论述相关的红外目标自动检测算法,并给出了系统硬件的设计与实现。该系统对焦平面热像仪输出的模拟视频数据进行A/D采样,通过CPLD和USB2.0高速总线把图像数据传回PC,在PC上对方孔目标进行自动检测并计算NETD。
A method for auto NETD-measuring of focal-plane thermal imaging systems is designed. The IR object＇s auto detection, the design and implementation of hardware are also given. The system acquired image data from the thermal imaging systems, and sent the digital image data to PC with the help of CPLD and USB2.0. Object＇s auto detection and NETD＇s calculation would be done on PC.
