摘要
采用稀少控制点区域网平差法对资源三号HRG卫星影像进行试验,并对试验成果DOM进行平面和接边精度检测。结果表明:该方法制作的DOM能满足1∶25000精度要求,可实现对不同轨道、不同时相的资源三号HRG遥感影像进行大批量快速处理与生产,有效解决了控制资料相对较少且分布不均的问题,较好地避免了不同轨道影像之间接边差大导致后续影像镶嵌困难情况的发生。
Based on block adjustment with few control points, HRG satellite image of ZY3 was processed and the precision of plane and edge match was analyzed based on the results. Result of experiment show that, the quality of product adopted the scheme accorded with the national standard of 1 ： 25,000. This paper realized mass high resolution satellite image which was in the different phase,orbits and high degree of overlap fast processing and avoided the trouble of image mosaic which was due to different orbits, with few unevenly distributed control points.
