摘　　要：选取山西省和新疆省部分地区实践9号卫星动态遥感监测数据为研究对象,通过对比两种不同的影像处理流程,对遥感影像纠正、配准、融合过程进行测试分析,为新型遥感数据源的正射纠正方法提供一定的参考。测试结果表明,先将全色影像与多光谱影像配准、融合,再与基础底图进行校正的影像处理流程,以及基于Rubber Sheeting模型的正射校正方法和HPF融合算法得到的影像效果最好,最适用于实践9号卫星影像DOM的制作。对于平原地区,在有DEM的基础上,使用IKONOS模型处理实践9号数据也具有一定的可行性。This paper regard the Practice No.9 remote sensing images from Shanxi and Xinjiang province as the research object, aim to test and analysis the process of correction, registration and fusion. Compared with the two different image technological process, the test results show that it’s a better process to registration and fusion firstly and fusion secondly. What’s more, it can get the best effect to use the Rubber Sheeting correction model and HPF resolution image merge algorithm towards the No.9 satellite images DOM production practice. IKONOS model also has certain feasibility for No.9 satellite images data processing practice combined with DEM actually in plain region but not in mountainous regiont.
