摘　　要：本文以向家坝、溪洛渡水电站输电线路走廊规划工程试验区为研究对象,分析了基于DMC数据的精度估算,探讨了在外业控制中的布点方案,重点对DMC影像用于空中三角测量的精度做了实验和分析,为其在电力勘测工程的规范化应用提供了基础,最后对DMC航摄影像的应用得出了一些结论,为后续的基于DMC数码影像输电线路工程勘测中的像控点布设提供一定的指导作用。Taking the Xiangjiaba-Xiluodu hydroelectric power station project as the example, this paper discussed the accuracy estimates about DMC image data and the layout of photo control points in the aerophotogrammetry. And the data accuracy of aerial triangulation measure based on varies of the layout methods of photo control points were analyzed through actual experiment. In the final, some experiment conclusions were drawn about the application of DMC image. And it could produce a reference for the layout of photo control points of the DMC image.
