随着计算机技术与视频图形图像技术的不断发展,机载航空电子系统中的综合显示处理技术也得以长足发展,需要处理和显示的视频信息量越来越大,格式越来越多。文章研究能够在机载综合显示系统中实现多种视频格式的选择和叠加功能。结合机载综合显示系统对视频技术的需求,研究了高性能多格式视频叠加模块的硬件设计和软件叠加算法。在机载综合显示系统液晶显示器上实现了叠加后的视频图像,满足了机载显示系统的要求。 With the continuous development of computer technology and video graphics and image technology, the integrated display processing technology in airborne avionics systems has also been developed rapidly. The amount of video information that needs to be processed and displayed is getting larger and larger with more and more formats. The article research can realize the choice and the superposition function of many kinds of video formats in the airborne integrated display system. Combined with the demand of video technology for the integrated airborne display system, the hardware design and software stacking algorithm of high performance multi-format video overlay module are studied. In the airborne integrated display system to achieve a superposition of liquid crystal display video images to meet the requirements of airborne display system.
