摘要
结合当前嵌入式产品的发展方向,提出了一种基于ARM9和Linux的嵌入式视觉系统,阐述了其硬件架构与软件组成,通过配置和加载各种设备驱动程序,利用V4L接口函数实现图像采集与显示。设计的嵌入式视觉系统体积小,成本低,可移植性强,通过实验波形和数据验证了其具有良好的图像采集和显示性能。
The embedded technology was becoming more and more popular in various fields.Thus,embedded vision system based on ARM9 and Linux was proposed.It has expounded hareware structure and software composing.The image gather and display＇s program were written with B4L interface functions by configging and loading kinds of device drivers.The embedded vision system designed has some characteristics such as little volume,low cost and better transplant.The experiment wave and data show it has better performance of image gather and display.
