摘　　要：介绍了DirectShow视频处理技术框架和用VRM9实现在输入视频画面上叠加任意图像的方法。基于离屏绘制方式,开发了用传统GDI接口绘制视频叠加图像的软件模块,规避了直接使用DirectShow的复杂性,降低了开发难度。用该模块制作了某型装备训练仿真软件的视频端,实现了标尺等视场信息的动态在屏显示。The DirectShow video processing technology and the method for superimposing any images On Screen Display（OSD） by using VRM9 are introduced.A software module was developed which used traditional GDI Drawing interface to build up off-screen bitmap and mixed bitmap into video display.The method avoided the complexity of direct DirectShow usage and reduced the difficulty in OSD development.The module was used to design a video terminal of a certain training simulation software,and realized the dynamic on screen display of status information.
