    摘要:

    为了满足机载综合显示系统在数据存储量、显示实时性、芯片处理速度等方面的高要求,设计并实现一种机载综合显示系统。系统以FPGA为主要开发平台,利用其丰富的设计资源配合CMOS摄像头实现视频的采集,视频进行插值处理后通过DDR2 SDRAM实现数据的高速缓存。在图像处理过程中同时生成当前所需叠加的仪表图形,最终将仪表图形叠加到视频中并送入显示器显示。经验证,系统可以在60帧/秒的视频上进行全姿态指示仪和全罗盘仪表图形的叠加,每个像素大小为16 bit,支持的最大分辨率可达1920×1080。

    Abstract:

    Aiming at the high requirements of data storage capacity, realtime of display and chip’s process speed in airborne display system, a type of airborne display system has been designed and implemented. FPGA is used as the main development platform in the system, using its rich design resources to achieve the video data by CMOS camera, after interpolation processing, the video’s cache can be realized by SDRAM DDR2. The instrument graphics which needed to be superposed also generates in the process of image processing, final, superposing the instrument graphics to the video and transferring into the display. Through verification, the graphics of instrument, such as attitude direction indicator and the compass, can be superposed on the 60 frames per second video, each pixel size is 16 bit and the video’s maximum resolution is 1920× 1080 in this system.
