| 摘 要： | 文中提出了一种对卫星全景图象进行整幅几何粗处理的方法。该方法基于卫片和地面上一些固有的几何关系,既考虑卫星成像的物理过程,又不单纯依赖卫星参数,而是借助于精确测定的少量地标点和几何关系模型,对参数进行最优估计,最终达到对图象的校正。经仿真表明,文中所提出的方法是完全有效的。

| Abstract: | A method used for the rough geometric rectification of full-size satellite panoramic images is proposed. Based on some intrinsic geometric relationships between the image and the ground, this method relies not only on the innate course of satellite panoramic imaging, but also on a small number of ground control points which are selected and measured accurately. POWELL method for the optimization of parameters is used here in the model. Simulation results show that this method is efficient for the coarse pre-processing of the satellite panoramic images. |
