天狼星无人机免像控技术在基础测绘更新中的应用

Application of Sirius image-free control technology in basic surveying and mapping update

无人机具有机动灵活、适应性强、获取影像分辨率高等优点,是航天遥感和航空遥感的有效补充。文中介绍了天狼星无人机航测系统的特点,探讨了影像获取的技术流程,研究了正射影像制作的方法,利用实地测量检测点对正射影像精度进行了的统计分析。结果表明,天狼星无人机航测系统在免除地面像控点布设的条件下,制作的正射影像满足基础测绘更新的要求。

Unmanned Aerial Vehicle (UAV) had the advantages of flexibility, adaptability and high image resolution. It was an effective supplement to the space remote sensing and the aerial remote sensing. In this paper, the characteristics of Sirius UAV aerial survey system were introduced, the technical process of image acquisition was discussed, the method of making orthophoto image was studied, and the statistical analysis of the accuracy of Orthophoto Image was carried out by using the field measurement detection points. The results showed that the Sirius UAV aerial surveying system could produce orthophoto images to meet the requirements of basic surveying and mapping updating without the placement of ground image control points.
