| 摘 要： | POS(DGPS/IMU)技术能够获取航摄瞬间航片外方位元素,采用POS技术进行空三加密和DLG制作,能够节省大量的外业控制点,这对提高航测地形图生产效率,降低成本具有重要意义。本文主要研究POS技术在平原地区1:10 000地形图生产中的外业控制点布设。设计了二十三种外业控制点布设方案,采用集成传感器定向法进行空三加密试验,在实验结果的基础上选择精度符合要求的数据制作了一幅1:10 000DLG,并对其进行精度测试。通过试验和研究,提出了合适的外业控制点布设方案,为POS技术应用于大规模航测4D产品生产做好技术准备。

| Abstract: | POS(also called DGPS/IMU) technique can obtain the Exterior Orientation Elements of aerial photo,so the triangulation and DLG production using POS can save large numbers of ground control points(GCP),and this will improve the productive efficiency of DLG and reduce the cost of collecting GCP.This paper mainly researched on POS technique in production of 1:10 000 scale DLG on GCP distribution.It designed 23 kinds of ground control points distribution schemes,using integrated sensor direction method to do the... |
