摘要
设计了一种基于Altera的NIOS Ⅱ嵌入式处理器的红外图像在线采集及显示系统。此系统能实时接收到的红外图像显示在LCD触摸屏上,并通过LCD触摸屏选择图像增强的方法,如增益电平法、自适应线性拉伸法、平台直方图均衡法等红外图像显示常用的预处理方法。实验表明红外图像增强算法的处理时间小于25 ms满足实时显示的要求。并且该系统工作性能稳定,处理效果良好,体积小,便于携带,完全能够满足野外操作等场合。
A new real-time image display system is designed for IR imaging based on Altera＇s NIOS Ⅱ.This system can receive IR image from IR focal-plane arrays and display it on LCD in real-time way.While,this system can select some image enhancement methods to make the IR images be good look.Now these image enhancement methods are gain-level method,adaptive linearscale method and plateau equalization method.Experimental results indicate that this system can be goodly used in such situation as field,out-door.Further,it has small size,portable,real-time display etc.merits.
