摘　　要：航空遥感图像有着特殊的几何畸变特性以及现实中无法及时获取野外控制点的限制条件,无法使用传统的几何校正方法对图像进行处理。针对航空遥感图像的限制条件,本文使用了无地面控制点的航空遥感图像几何校正模型对图像进行处理。通过实验对比仿射变换模型和多项式变换模型的校正效果,得出仿射变换模型更能适用于本文情况,更能改善图像效果。在几何校正过程中,提出了一种控制点的最佳选取方案,实验结果表明,该方案可以有效配合图像几何校正的实施。With the development of sensor technology, aerial remote sensing images are widely used in various fields, but the aerial remote sensing image has special geometric distortion characteristics and the field control point cannot be accessed timely in practice. So the traditional geometric correction method for image processing cannot be used. In this paper, the geometric correction model of aerial remote sensing image without ground control point was used to deal with the aerial remote sensing image. Compared with the affine transformation model and the polynomial transformation model, the affine transformation model is more suitable for the situation in this paper, and can improve the effect of image. In the geometric correction process, a control point selection scheme was proposed. Experimental results show that the proposed method can effectively coordinate the implementation of image geometric correction.
