针对弹载图像采集系统设计中存在无法准确稳定存储高速数据流,而导致图像信息记录和存储的可靠性严重降低的问题,设计了一种基于PAL制图像数据的无延时存储方法.通过采用乒乓缓存设计和流水线结构方式,解决了高速图像数据输出和串口Flash存储器的低写入速度不匹配的问题.通过实验分析验证,设计能够解决高低速存储介质中速度匹配问题,实现对高速图像数据的精确存储和记录,为后期图像恢复提供了可靠的数据.%There is a serious problem in missile-borne image acquisition system that high-speed image data stream can not be stored accurately and stably,which will result in the decrease of image information recording and storage reliability seriously.In order to solve this problem,an un-delay storage methods of image data based was designed on PAL mode.This method ping-pong buffer design and pipe-line structure was used to solve the write speed mismatch problem between high-speed image data output to low-speed of serial Flash memory.Through experimental image analysis,the problem of speed match problem in the high and low speed storage media can be solved,accurate storage and recording of high-speed image data can be achieved.This design provided reliable data for later image restoration.
