摘要
描述了一种优于传统方法的图像采集、记录和显示系统,即基于现代先进的电子器件、计算机技术和编程方法,以高速、高精度(12bit)A/D转换器采集红外焦平面阵列的图像信号,通过XMS规范调用,以微机扩展内存或硬盘连续、实时存储大容量的数据,同时通过微机的显示(加速)卡,以VESA扩展模式将256级灰度动态地显示于显示器上。记录的数据可以随时、灵活调用,进行DSP算法仿真、时域和空间噪声分析、非均匀性校正算法研究以及前视红外系统、红外搜索与跟踪系统指标的评估等。
A sampling, recording and displaying system for IRFPA which takes good advantage over the tradition is described. Based on the advanced modern electronic devices, computer technology and programming, it samples and converts the image signal from IRFPA at high speed with 12 bit precision, continuously saves the quantity data on EIDE hard disk or extended memory according to XMS in real time, and dynamically displays the gray image of 256 levels on the SVGA display in expanded VESA mode. The recorded data can be recalled anytime at various ways, applied to DSP simulation, temporal and spatial noise analysis, NUC algorithm research, evaluating the FLIRS and IRSTS, and so forth.
