分析了引起机载多光谱扫描图象几何畸变的各种主要因素，提出并建立了利用由惯性导航系统同步记录的飞机姿态、运动和位置参数校正机载多光谱扫描图象几何畸变的方法模型。试验结果表明，与传统采用控制点的方法相比，该方法不仅具有较高的校正精度，而且可由计算机全自动完成。

Various major factors causing geometric distortions of airborne multispectral scanning images were analyzed, and a method to correct geometric distortions of airborne multispectral scanning images by using the orientation, movement and positional parameters of airplane recorded by Inertial Nevigation System is proposed. Test result indicates that compared with the traditional method-GCP, this method not only yields better accuracy, but also can be performed automatically by the computer.
