摘要
遥感影像图质量的评价研究近些年主要集中在色彩质量评价及影像质量评价上,并有部分评价软件推出。笔者在研究的基础上,设计了遥感影像质量评价体系,提出了影像质量评价二级指标及相应权比,介绍了几何质量、色彩质量评价原理,最后设计并实现了遥感影像质量评价系统,并选择6种遥感影像图进行了色彩质量评价试验,以机助形式实现了半自动化的影像生产质量定量评价。结果表明:系统具有操作简单,定量客观等特点,可应用于遥感影像质量评价实践。
In recent years, remote sensing image quality evaluation studies have focused on thecolor quality assessment and evaluation of image quality, and some evaluation softwares were re-leased. On the basis of these studies, the remote sensing image quality evaluation system was de-signed,its secondary indicators and corresponding weight ratio were established, the evaluationprinciple of geometric quality and color quality were introduced, and finally, the remote sensingimage quality evaluation system were implemented to achieve semi-automated quantitative evalua-tion of image quality in computer aided form six kinds of remote sensing image. The results showthat the system has many advantages such as simple operation, quantitative and objective analy-sis, and thus can be applied in remote sensing image quality evaluation practice.
