以高精度影像数据为基础,采用DPGRID.OrthoUpdate软件,基于已有高精度正射影像数据,实现影像数据的快速纠正更新。通过外业控制点或DLG成果数据,对更新成果进行检测,并进行精度、效率等分析,以评价分析基于DPGRID.OrthoUpdate的DOM的快速更新,从而实现对现有的高精度影像有效利用的目的。 更多还原

【Abstract】 Based on high resolution image data,applying DPGRID.OrthoUpdate software and existed high resolution orthophoto,this paper implemented the quick rectification of image data.It also carried out the analysis on accuracy and efficiency by checking the updating results using ground control points and DLG data.It evaluated the quick DOM updating by DPGRID.OrthoUpdate for the purpose of effective application of high resolution image. 更多还原
