| 摘 要： | 空中三角测量是利用航摄像片与被摄目标之间的空间几何位置关系,根据少量的野外控制点,计算节点的平面坐标与高程以及航摄像片的外方位元素的方法,是摄影测量过程中的重要环节。随着导航定位技术的发展,高精度POS装置被广泛安装到航拍飞机上,用于记录航拍时刻相机的位置与姿态,从而进行辅助空中三角测量。本文研究利用双高度层的ADS40航线影像,结合POS数据,利用一定数量的控制点,基于ORIMA软件进行空中三角测量,并对其解算精度与同一区域单高度层航线影像的空三精度进行比较。 |

| Abstract: | Aerial triangulation,which is the crucial part in the photogrammetry process,is a method to calculate the plane coordinates and elevation of the tie points and the exterior orientation parameters of the photo based on some amount control points.With the development of navigating and positioning technique,highly accurate POS system is equipped on the aerial aircraft to record the position and attitude of the camera at the shooting moment,which is used to support the aerial triangulation.In this paper,it used the two flight levels ADS40 imagery data,POS data and some ground control data to perform aerial triangulation based on ORIMA software.And finally the accuracy of the aerial triangulation with two flight levels imagery data was compared with that of the solo flight level imagery data. |
| Keywords: | aerial triangulation self-calibration block adjustment ADS40 ORIMA RMS |
