基于PCI GXL的国产卫星影像快速正射纠正方法的研究

Research on fast ortho rectification method about domestic satellite images based on PCI GXL

随着卫星遥感技术的不断进步,国产卫星遥感在国民经济和社会生活中发挥的作用也越来越重要。为了高效精确地对大量的国产卫星影像进行正射纠正,文中针对国产卫星影像数据的特点,使用PCI GXL软件集群系统,以自动化的工作流作业模式,在长期生产作业实践中不断探索总结,形成了一种有效的快速正射纠正方法。得到的正射影像成果能够满足地理国情监测等重大测绘地理信息项目的使用要求,为各个项目的顺利开展,提供了高效精确地数据保障。

With the development of satellite remote sensing technology, domestic satellite remote sensing had played an increasingly important role in the national economy and social life. In order to accurately and accurately correct a large number of domestic satellite images, in the paper, PCI GXL software cluster system used to analyze the charac- teristics of the domestic satellite imagery data with the automate workflow operation mode, and an effective fast ortho- rectification method was formed in the long -term production practice, ongoing exploration and summary. Achieve- ments of the orthophoto imaging could meet the use requirements of geographical conditions monitoring and other ma- jor mapping geographic information project providing the efficient and accurate data protection for the smooth devel- opment of various projects.
