| 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。利用DMC影像进行1:1000航测数字化成图进行野外像控点布设时,可考虑采用区域网法，但跨越几条基线最为合适，没有规范和相关文献给出明确的说明。本文利用安徽省数字城市建设北方平原的航摄资料，对野外像控点布设选取四种不同的方案进行试验分析，总结出最适用于DMC影像的像控点布设方案，以提高生产效率，节约生产成本。 |

| Having a range of advantages over traditional film scanning, digital aerophotos are being widely used in photogrammeric mapping. Strip method is recommended when arranging field control-points for DMC-based digital mapping on the scale of 1:1000. However, there is no specification on the number of baselines in the existing literature. 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. |
