航空摄影测量中像控点的选择与布设

Preliminary Discussion on the Selection and Layout of Image Control Point of Aerial Photogrammetry

航空摄影测量中像控点位置的选择与布设直接影响到内业成图的数学精度和工作效率的最大化。以大同市1∶500成图比例尺要求的数码航空摄影项目为基础,通过分析像控点点位选择的基本要求、像控点的布设方案和施测方案,提出了内外业工作中常出现的问题并结合实践归纳总结了一些像控点选择与布设方面的技巧与方法。

Selection and layout of image control point position in the aerial photogrammetry has directly influence on mathematical precision of mapping and maximize efficiency. The basic requirement of image control point position selection,layout scheme and surveying scheme of image control point are introduced which are based on the project of 1 ∶ 500 mapping scale requirements of the digital aerial photography in Datong city. Some problems that often appear in the office and field work are proposed and some skills and methods of selection and layout of image control point are summarized which combined with practice.
