机载记录视频信息化系统的设计与应用

摘要

机载记录视频是由机载视频记录系统扪摄的飞机前方外景叠加在平视显示器画面上的组合画面;以LabWindows/CVI为软件开发平台,采用Vision开发模块获得OCR字符集,结合各类显示画面的布局,自动完成由记录视频向信息序列化的转换,实现了机载记录视频信息化系统,为机载记录视频后期分析提供了可靠的定量数据,并可实现机载记录视频的快速检索、合成显示、压缩存储,飞行过程三维显示,平视显示器性能分析等.%Airborne recorded videos (ARV) are the frames of Head-up Display (HUD) overlaid by exterior view on the front of the plane. To provide reliable quantitative data for ARV's later analysis, the system is based on LabWindows/CVI and vision development module to obtain OCR character set, and fulfils transforming ARV to information serialization automatically according to the layout of all kinds of display frames, and it can be applied in ARV quick retrieval, synthetic display, compression storage, 3D display of flight course and HUD performance analysis.
