| 摘 要： | 通过分析相机透视投影中的共线方程,结合相机内定向的原理,推导出了对于同一地物在不同航片上的图像坐标变换关系,应用该数学模型实现了航拍图像的几何校正,并且与二次多项式模型和双线性模型进行了比较,通过对实验结果的比较,显示出该方法在航拍图像几何校正中的优良特性。

| Abstract: | This paper analyses the collinearity equation of camera perspective projection,and makes use of interior ascertaining orientation theory.Therefore transform of image coordinate relation can be implemented in different aerial images about the same object.The geometric model is used to complete the geometric rectification,and it compares this model with quadratic model and double linear model.By comparing the experiment results,this projection model manifests its perfect speciality. |
