基于多项式正射纠正模型的机载SAR影像区域网平差

Block Adjustment with Airborne SAR Images Based on Polynomial Ortho-Rectification

    摘要
  • 摘要: 在SAR影像多项式正射纠正模型基础上,分别对平高点、平面点、高程点、加密点列出了误差方程,从而建立了基于多项式正射纠正模型的机载SAR影像区域网平差模型,并设计了相应的软件。利用成都测区的机载SAR影像进行了实验,取得了比较满意的结果。

     

    Abstract: This paper introduces four kinds of error equations about 3D GCPs,plain GCPs,elevation GCPs and pass points based on polynomial ortho-rectification of SAR images;and then a block adjustment model of SAR images is given.According to this model,program has been designed and experiment has been done on airborne SAR images of study site in Chengdu.The experimental results are feasible.
