摘要
数字图像的实时存储是视频判读的基础 ,经常使用模拟录像机把视频信息记录在磁带上 ,由于磁带录像机的分辨率不高 ,影响判读的精度。本文针对数字图像的特点 ,提出了一种新型的、基于计算机硬盘的视频存储方法 ,其目的是简化判读系统的结构 ,提高判读的精度。它利用了数据压缩原理 ,对视频信号进行实时、无失真的压缩 ,再把压缩后的数据进行存盘 ,实现了视频图像实时存储。试验表明 ,用此方法可以完成 51 2× 51 2的视频图像的实时存储 ,且结构简单 ,方法实用 。
The realtime storage for digital image is the base of video interpretation. With often recording video signal on the tape, low precision, however, is obtained beacause of the low distinguishing of video tape recorder. A method of realtime video storage is studied in the light of the characteristic of digital image, which make HD be a media through lossless compression of digital image. Realtime restorage for 512×512×8bit video image can be realized by this method, and the architecture is simple and practical. So it is a new video storage method.
