| 摘 要： | 提出了一种基于海岸带水边线等高条件的航空影像外部定向方法,该方法将局部区域水边线上各点的高程值相等作为控制条件,在立体像对的外部定向中,引入这些等高点,和其他平高控制点一起参加平差,计算立体像对的绝对方位元素.实验证明,该方法能够有效地提高航空影像的外部定向精度,尤其是高程的定位精度,提高了海岸带地形的测图精度.

| Abstract: | In this paper,an exterior orientation method of aerial imagery which was based on the equal-altitude condition of the coastline was proposed.This method regarded that points on the line of water area of a local area were equal in elevation as a control condition,and in exterior orientation of the stereo images,introduced these equal-elevation points into the adjustment,calculating with elements of exterior orientation of the stereo images.The experimental results indicated that the method improved the preci... |
