无人机航空摄影是一种新型的低空遥感影像获取方式，其中像控点布设是利用航测进行数字测图和制作正射影像图(DOM)的重要环节，其布设效率将直接影响后续的工作进度，而且像控点布设的网型也是影响最终测图和DOM精度的重要因素。本文主要介绍了传统的无人机影像像控点布设方式，分析了传统布设方法存在的缺陷，并针对传统手动布设像控点的缺陷，研究开发一种全新的像控点自动布设程序，省略了传统布设方式所需的大部分人工操作，极大地提高了像控点布设的工作效率。%UAV aerial photography is a new kind of low altitude remote sensing image acquisition method. The layout of photo control points is an important part in digital mapping and doing orthophoto map (DOM) which uses aerial survey. Its layout efficiency will directly affect the subsequent work schedule. And the net type of control point layout is also an important factor affecting the final mapping and DOM accuracy. This paper introduces the layout method of traditional UAV image control point, analyzes the defects of traditional layout methods and develops a new image control point automatic placement program for the defects of traditional manually setting image control points. This method omits most manual operation required and greatly improves the image control point layout efficiency.
