| 摘 要： | 高分辨率卫星的发展使遥感影像的广泛应用成为可能,在摄影测量领域具有重要意义的核线是高分辨率光学遥感影像应用的基础。本文基于有理函数作为通用的几何模型研究线阵CCD影像的理论依据,在一种新的有理函数反演模型基础上,确定像点的虚拟物方点,利用核线投影轨迹生成算法获得核线在左右影像范围内的走向和形状,结合3组不同传感器获取的不同地区的遥感数据进行了本文方法的验证,证明其有效性,证明本文方法可以快速高效地实现核线提取。

High Resolution Optical Satellite Remote Sensing Image Epipolar Line Extraction |

| Abstract: | With the development of high-resolution satellite, a wide range of applications of remote sensing become possible.Epipo-lar line, which is of great significance in the field of photogrammetry, is the foundation of the application of high-resolution optical remote sensing.In this paper, we use rational function as general geometric modeling to study the linear CCD images, and determine the virtual points of image points based on a new inversion model of rational function, and obtain the scope and shape of the epipolar line in the left and right images in the method of trajectory generation of epipolar line’ s projection.Then, we test and verify the effec-tiveness of the proposed method with the remote sensing data obtained from three different sensors in different areas.The result shows that we can extract epipolar line quickly and efficiently through the proposed method. |
