摘要
介绍了一种针对凝视红外图像预处理应用而设计的FPGA硬件算法结构,该结构充分发挥了FPGA高速、并行计算能力,能在信号读出过程中实时地完成红外图像非均匀性校正(基于定标)、盲元补偿、邻域处理(卷积滤波/中值滤波)以及直方图统计等功能。将该结构应用到凝视红外系统的前端,不需额外占用处理时间,为后端信息处理节约出时间,是一种高效、快速的预处理方案,并在实际的成像实验中得到了验证。
A FPGA algorithm structure designed for the starring IR image Pre-Processing is introduced The structure takes advantage of the high speed and parallel computation of FPGA. It has the function of real-time processing of non-uniformity correction （based on calibration）,, blind-pixel compensation, neighbor-region processing （ convolution filter/median filter） and histogram statistics. The application of the structure in the front-end of starring IR system will be time saving for the back-end processing. It is a fast and efficient pre-processing scheme in the imaging experiment.
