| 中文摘要: |
| 目前航测成图所使用的航摄资料多数是数码航片,数码航片相比传统的经扫描数字化的胶片有很多优点,传统的1﹕1000航测数字化成图像控点布设按规范要求采用全野外布设,该法工作量大,外业作业周期长。本文利用安徽省数字城市建设北方平原的航摄资料,对野外像控点布设的不同方案进行试验研究,分析总结适用于DMC影像的像控点布设方案,以提高生产效率,节约生产成本。 |
| 英文摘要: |
| Having a range of advantages over traditional film scanning, digital aerophotos are being widely used in photogrammeric mapping. Traditional control-points setting for digital mapping on the scale of 1:1000 requires a large number of points covering the whole area, which is both time-consuming and energy-consuming. This paper discusses different designs of control points using the aerophotos for the project of Building a Digital Anhui as the data. The paper discusses the best design applicable to DMC-based images to increase productivity and reduce cost. |
