| 摘 要： | 将嵌入式和Linux相结合,设计并实现了一套双路图像的采集与传输系统.该系统以CM-T3530核心板为硬件核心,首先根据系统要求编译并安装Linux嵌入式操作系统,并利用视频接口V4L2实现红外图像和彩色图像的双路采集.然后举例说明如何在核心板上利用有效的进程通信方式将两路图像的优势结合,最后将处理过的图像信息利用套接口传输到远程计算机上显示.该系统是小型无人机自主导航与控制的视觉导航以及以无人机为平台的灾害检测的基础,有很好的应用前景.

| Abstract: | This paper introduces the design of dual images acquisition and transmission based on embedded platform in detail. The system is based on Intel embedded microprocessor PXA270 as its hardware core. First of all we should install proper Linux embedded operating system according to requirements of the system. By use of video interface V4L2 the dual capturing of infrared image and color image can be achieved. Then we may apply process communication to combine advantages of two kinds of image. At last the system should transmit images to the remote computer for displaying by use of socket transmission. The system can be used as the basement of visual navigation and disaster detection, where small UAV is applied as the implementation platform, which has broad application prospects. |
