| 摘 要： | 提出一种对已知相对方位元素的立体影像实施灰度重采样生成核线影像对的方法,对连续像对相对方位元素和独立像对方位元素建立核线影像的理论公式进行了推导,建立了核线影像和原始影像的坐标变换关系;为了提高核线影像建立的效率,在进行核线重采样时,提出分块读写影像的方法。实验表明,建立的核线影像上下视差在亚像素水平,核线影像坐标反算后与原始影像的坐标平均差只有0.000 3个像素,完全可以满足摄影测量立体观测的要求。

| Abstract: | This paper put forward a method of generating epipolar images using the relative orientation on aerial stereo image pairs.Firstly,this paper made a deduction about relevant theoretical formulas of generating epipolar images,by using the elements of relative orientation of consecutive photo connection and independent image pair respectively,which in return helps to establish their coordinate transformation relations.Then with the aim to improve the efficiency of epipolar images generation,the paper proposed ... |
