Google Earth辅助下的高分辨率遥感影像区域网平差
Block Adjustment of High-Resolution Satellite Images with Google Earth
摘要
Abstract
In response to the actual requirements of geo-positioning at abroad of domestic satellite images,a method of block adjustment of high-resolution satellite images with control points measured by Google Earth was proposed.Firstly,the coordinate system was united by transforming the altitude of measured control points into geodetic height,then the measured control points were used as control points with low accuracy in block adjustment.The experiments were divided into two cases which were without ground control points and with few.Several schemes were proposed for two cases to analyze the effects on geo-positioning accuracy by Google Earth.Experimental results indicated that the geo-positioning accuracy of this method was increased obviously.The proposed method in this paper provided a new way for geo-positioning at abroad of optical satellite images without enough ground control points.关键词
