摘要
航空图像覆盖范围广,包含巨大的信息量。预先了解影响图像质量的各种原因,有针对性地进行图像质量判别,可以减少信息冗余,提高运算速度。而且, 大多数航空图像都没有参考图像,属于绝对图像质量判别范畴。有资料表明,在当前的技术状态下,只有预先了解引起图像降质的原因,对无参考图像进行质量判别才是可行的。本文对影响航空图像的主要因素进行了分析和归纳,并指出了各种因素对图像质量造成的影响,为进行航空图像质量判别提供了方向。
Aerial images cover wide areas and include huge information. By knowing the fators affecting the quality of images, then evaluating the image quality aimly, the redundant information can be reduced and the processing speed can be optimized. Furthermore, there are no references for many aerial images and it is feasible to evaluate image quality only by knowing the cause of degrading image quality. Main factors affecting image quality are analyzed and concluded, and the way to evaluate aerial image quality is provided.
