基于VxWorks操作系统的雷达显示软件屏幕截图技术研究

Research into The Screen Image Interception Technique of Radar Display Software Based on VxWorks Operation System

介绍了基于VxWorks嵌入式操作系统下雷达终端显示软件对显示画面截图的实现技术。该技术使用Open-GL图形接口的帧缓存获取雷达屏幕航迹图形信息数据,并将该数据以标准的BMP图形文件格式保存。该BMP图形格式文件在Windows操作系统下可以被一些通用的图形软件浏览。

This paper introduces the realization technique of radar terminal display software to the display frame interception based on VxWorks embedded operation system.This technique uses the frame buffer of OpenGL graphic interface to fetch the information data of radar screen track,and saves the data with the standard BMP image file format.This BMP image format file can be browsed by some general graph software in Windows operation system.
