摘    要:针对利用遥测信道准实时传输机载大面阵高速相机图像问题进行了研究,设计了一套大面阵高速相机图像准实时下传系统,分析了图像数据下传的实时性.该系统在记录高速相机原始图像的同时,可对图像进行抽帧、缩小画幅、压缩处理,并实时下传到地面用于监视.分析表明,该系统能在靶场试验结束后几分钟内,将关键时间段的原始图像逐帧下传到地面,实...

关 键 词:机载高速相机  准实时  图像传输  图像压缩  遥测信道

Abstract:Near real-time download of images from airborne large array high speed camera through a telemetry channel is studied.A near real-time image download system is designed and its real-time performance is analyzed.While recording the raw images of a high speed camera,the system can extract frames,zoom in the pictures and download the compressed images to the ground for monitoring in real-time.The raw images in a key time segment can be downloaded to the ground frame by frame a few minutes after conclusion of a test,thus enabling near real-time image download.Therefore,it is no longer necessary to wait for landing of the airplane to view the images of the high speed camera.This provides strong technical support for decision-making during range tests and follow-up tests.
Keywords:airborne high speed camera  near real-time  image download  image compression  telemetry channel
