GIS知识引导的正射影像变化检测及更新

GIS Knowledge Guided Change Detection and Update of Digital Orthoimage

    摘要
  • 摘要: 针对数字正射影像变化检测问题的复杂性,提出了一种基于GIS知识引导的多维变化模板分析方法,探讨了由粗到细的四叉树变化检测模板生成方法和一些利用GIS知识的专家打分方法。利用此方法,对一个实验区不同时期的数字正射影像进行了变化检测和正射影像库的更新,达到了预期的目的。

     

    Abstract: A new method using multidimensional change template analysis guided by GIS knowledge is proposed in this paper. The new method combine the use of quad-tree change detection template and GIS knowledge. It has been used to detect change among different temporal digital orthophoto maps (DOM) and then update image database. Test results show that this method is effective reliable and robust in many cases.
