摘要
该文介绍了一款基于ARM嵌入式平台开发出能够生成多种图片格式和简单图像处理的相机系统的设计和开发。该系统基于QtDesigner设计操作界面,并将摄像头启动、画面捕捉和照片存储作为多个线程添加进函数体内,使其同步运行。系统采用开发板的显示屏作为照相机的显示设备,并利用Video4Linux视频处理接口进行图像采集,最后附加设置图片参数或者优化文件存储等操作。
This paper introduces design and development of a camera system which can generate a variety of image formats and simple image processing based on ARM embedded platform. The system is based on Qt Designer operation interface, and take camera start, screen capture and photo storage as multiple threads added to the function body, so as to operate synchronously. The system uses the display of the development board as camera display device, and takes advantage of Video4Linux video processing interface for image acquisition, finally, adds to picture parameter set or optimize file storage and other ooerations.
