摘　　要：基于嵌入式Linux环境下图像采集及在嵌入式开发板上对图像显示的目的,本文研究了视频采集及显示的一般方法,并将飞凌公司OK6410开发板与嵌入式Linux操作系统相结合,通过对内核的定制、交叉编译程序及基于Qt/Embedded设计图像显示GUI,最终实现了嵌入式Linux平台下USB摄像头对图像的采集以及在开发板上的显示,并且在开发板上实现了对显示图像的简单操作。For the purpose of image acquisition based on embedded Linux environment and image display in the embedded development board, this paper studies the general method of video capture and display, and combined the 0K6410 development board of Feiling company with embedded Linux operating system. Through customizing kernel, cross-compiling procedure and designing image display GUI based on Qt/Embedded, we ultimately achieve image acquisition in the embedded Linux platform and display in the development board by USB camera,and simple operation in the development board of the displayed image.
