摘　　要：本文简要介绍了IKONOS遥感卫星系统及其立体影像数据的特点,给出了IKONOS影像立体模型的构建原理与方法,探讨了IKONOS影像的区域网平差方案,对少控制或无控制测图做了初步分析。随后,描述了JX4C数字摄影测量工作站中对IKONOS立体影像从数据预处理、单模型定向、区域网平差到区域DLG、DEM/DSM、DOM等测绘产品生产的一体化处理流程。文章最后指出,以IKONOS为代表的高分辨率遥感影像在测绘领域的广泛应用标志着卫星摄影测量与制图时代的开始。In this Paper,IKONOS satellite system and its imaging system is briefly introduced;the principle and method of IKONOS stereo model construction are described;block adjustment with no Ground Control Point(GCP)or a small quantity of GCPs is discussed. And the workflow of IKONOS stereo from data preprocessing,single photo-pair orientation,block adjustment,and DLG, DEM/DSM,DOM generation in JX4C DPS is presented.In the last section,the authors point out that the mapping application of high spatial resolution remote sensing imagery represented by IKONOS indicates the beginning of satellite photogrammetry era.
