| 摘 要： | 与卫星遥感传感器相比，机载成像光谱仪具有平台姿态稳定性差、飞行高度低、视场角较大等特点，这些因素的结合使图像几何畸变的图案复杂化，几何纠正的目的就是尽可能消除这些几何畸变。该文详细分析了OMIS图像存在的主要几何畸变，提出OMIS图像几何校正的处理流程，试验结果表明该方法能取得较好的校正效果。

| Abstract: | The platform posture of low-altitude airborne image spectrometer is less stable and its Field of View (FOV) is broader than that of spaceborne remote sensors. It makes the geometric distortion of the image more complicated. The goal of geometric correction is to reduce these distortions farthest. The OMIS(Operational Modular Imaging Spectrometer) is an airborne image spectrometer developed by Shanghai Institute of Technical Physics of CAS and it has been widely used for hyperspectral remote sensing purpose in China since last decade. In this paper, the main geometric distortions of OMIS images are discussed. Besides, a method for geometric correction of OMIS images is presented in detail. The experimental results show that the presented method works very well. |
