| 摘 要： | 利用武汉大学自行建设的登封航空定标场和飞行试验数据,对数码航空相机DMC不同控制点分布下的几何精度进行了对比分析和评估。实验结果证明,DMC平面精度相对稳定,均匀布设控制点时间隔基线数量的减少,和密集周边布点时中心控制点的加布,均可以提高高程精度。

Geometric accuracy assessment of DMC imagery |

| Abstract: | By using the Henan Song mountain calibration test field built by Wuhan University and three flights image data, the attainable geometric accuracy of DMC imagery was evaluated, considering the distribution of the control points. The results prove that, The X/Y accuracy is stable, but the Z accuracy is improved, by reducing the number of the base station to adding control points and adding in the middle of the flight. |
