应用线性相关分析方法探讨国土卫片几何畸变纠正的精度

A Stundy on Correction Precision of Geometric Distortion on National Satellite Photograph by Means of Linear Correlation Analysis Method

我国卫星影像具有空间分辨率高,比例尺适中的特点。由于国土片是全景成像,比例尺变化大,用它来编绘专业地图,给精度衡量带来很大困难,需要对国土片进行几何校正。本文试图用线性相关分析方法,分析经过ARIES—Ⅱ图像处理系统纠正的国土片几何精度。以便为分析专题图精度提供依据,同时也为分析遥感影像几何精度介绍一种方法＊

The National satellite images have features of high spatial resolution and moderate scale. Due to the National satellite photograph is full-view image and it's scale changes greatly, it is diffcult to measure the precision when the thematic maps are drawn on basis of this photograph. The image needs geometrical distorsion correction. This paper try to primarily probe how to measure the precision by means of linear correlation analysis meth- od while the geometric distortion of the National satellite photograph is rectified with ARIES--Ⅱ image Processing system, so that it provides basis for analysing the precision of the thematic map, and gives a method of analysing the geometric precision of remote sens- ing image.
