资源三号测绘卫星长条带产品区域网平差

Block Adjustment of ZY-3Long Strip Scenes

  • 摘要: 目的 资源三号测绘卫星除了提供无畸变的标准景产品以外,还提供将近600km的长条带产品。该产品和标准景产品类似,生产过程中引入的投影差误差和交会误差可以忽略不计,有理多项式模型作为长条带产品的成像几何模型发布给用户。基于像方的仿射变换平差模型可以消除长条带影像中的轨道、姿态误差,达到子像素级定向精度。在周边布设控制点,资源三号测绘卫星三线阵长条带产品的平差平面精度约为2.5m,高程精度约为1.6m,达到单个标准景的平差精度。

     

    Abstract: Objective ZiYuan-3not only provides distortionless standard scenes for sensor corrected products butalso long strip scenes,whose length could extend almost 600km.The long strip scenes are similar tostandard scenes,whose mismatch and elevation errors,introduced by production procedures are ignor-able.A rational function model(RFM)for long strip scenes is provided.The image space affinetransformation is used to eliminate attitude and ephemeris errors in long strip scenes,and sub-pixelorientation accuracy is made available.When ground control points(GCPs)are deployed around thecorners of the survey area,the RMS(root mean square)of the plane and elevation of long strip sceneswas 2.5mand 1.6mrespectively.The accuracy is similar to the single standard scenes.
