基于UAV影像像控点选点方法探讨
|
摘要
低空无人机航摄是一种新型的低空遥感影像数据获取方式,其像控点布设、选刺是无人机影像数据生产的重要环节。尤其在地形复杂测区会增大外业刺点数量,不仅影响内业加密精度,更影响整个项目进度。针对这些问题,本文提出一种布设像控点的新思路,灵活利用常规测量小软件并结合多种技术手段,来提高外业像控点选刺效率。通过具体项目验证该方法的可靠性,这样既能提高外业像控点的选刺效率,也能保证内业加密精度要求。为以后类似项目实施提供较强的借鉴意义。
Low-altitude unmanned aerial vehicle(uav) photography is a new type of low-altitude remote sensing image data acquisition method. Its image control point layout and thorn selection are important steps in the production of uav image data. Especially the complex terrain measurement area will increase the number of field puncture points, which not only affects the internal industry encryption accuracy, but also affects the overall project progress. In order to solve these problems, this paper proposes a new idea of laying out image control points, so as to flexibly use the conventional measurement small software and combine various technical means to improve the selection efficiency of the field control points. The reliability of the method is verified by specific projects, which can not only improve the efficiency of selecting the field image control points, but also ensure the accuracy of the internal encryption. This will provide a strong reference for the implementation of similar projects in the future.
