【摘要】 介绍了一种对动态目标进行红外成像跟踪与辐射特性测量的系统。该系统采用大口径红外成像镜头,图像信号经放大、A/D转换和图像非均匀性校正,输出与目标辐射量成正比关系的数字图像信号。红外成像跟踪采用FPGA结合软件处理方法实现对目标的实时自动识别,进行形心、边缘与相关跟踪的计算。红外辐射特性测量采用基于PCI总线的高速图像采集板进行实时图像采集与显示。红外定标建立输出信号和标准黑体绝对辐射量的关系曲线,将原始的图像灰度数据换算为辐射通量密度。经外场试验证明该系统稳定可靠。更多还原

【Abstract】 A infrared imaging tracking and measuring system for dynamic target was introduced.By using large aperture infrared imaging lens and amplifying,A/D converting,NUC,the system produces digital image signal which in direct ratio with radiation of target.With the combination of FPGA and software design,auto target tracking is achieved.A high-speed image acquisition card based on PCI bus is designed to implement real-time image processing.As a result of infrared correction,curves of relationship between output signal and blackbody radiation were established to convert the original image data value into radiant emittance.The outdoor experiments have shown the stability and reliability of the system.更多还原
