航空遥感图像几何校正模型的效果比较

Comparison of Geometric Correction Models of Aerial Remote Sensing Images

随着传感器技术、计算机技术的发展,航空遥感图像也得到广泛的应用。针对航空遥感图像存在的几何畸变现象,在遥感数据预处理中几何校正是一个重要的环节,因此几何校正模型的选择很关键。比较仿射变换模型和多项式模型的校正效果,实验结果表明仿射变换模型对实验数据的校正效果更佳。

With the development of sensor technology and computer technology, aerial remote sensing images have been widely used. For geometric distortion in aerial remote sensing images, geometric correction is an important part in the remote sensing data preprocessing. Furthermore, the choice of geometric correction model is very important for geometric correction. Compares the effects of affine transformation model and polynomial model, the experimental results show that the affine transformation model has better effect on the experimental data.
