摘要
图像采集是进行图像处理的前提,而驱动图像采集设备又是实现图像采集的基础。针对嵌入式系统的图像采集,给出了基于LPC3250硬件平台和嵌入式Linux软件平台的图像采集系统。系统对摄像头设备进行静态加载驱动,并利用V ideo4Linux(V4L)视频采集应用程序接口编程技术编写图像采集程序,实现了基于中星微ZC301B DSP控制芯片的USB摄像头的图像采集。实验结果表明,该系统具有较好的实时性,采集到的图像对于进行进一步图像处理有重要的实际意义。
Image acquisition is the premise of image processing,and driving image acquisition equipment is the basis for implementing image acquisition.Aiming at the image acquisition upon embedded system,the image acquisition system based on LPC3250 hardware platform and embedded Linux software platform are given.The camera equipment is loading driven statically by the system,and the image acquisition program is written with the programming interface technology for Video4Linux（V4L） application program,the USB camera image acquisition based on ZC301B DSP control chip is implemented.The result of experiment indicates that this system features better real-time performance;and the images acquired are significant to further image processing.
