高精度姿轨参数卫星影像在1∶50000数据库更新工程DOM生产中的应用

针对1∶50 000数据库更新工程中高分辨率卫星影像几何纠正的情况进行总结,在充分利用缺少控制卫星影像几何纠正研究成果的基础上,通过大量的生产实验,提出常用传感器高分辨率卫星影像工程生产中的控制点数量和分布要求。对同轨同时相影像拼接后纠正和多源卫星影像联合区域网平差进行研究实验,并在控制困难区域的正射影像生产中进行验证应用。本文研究内容可用于指导同等精度要求的卫星正射影像工程生产。

Application of Satellite Images with High Accuracy Attitude and Orbit Parameter in DOM Production for 1∶50 000 Database Updating Project

In this paper,the ortho-rectifying scheme about high resolution remote sensing imagery was introduced,which mainly used for the project of map updating in China with the scale of 1∶50 000.With the lots of experiments for various imageries,the scheme about ground control points distributing and number was put forward,which was especially for large engineering project.The experiments about the imagery ortho-rectifying with same orbit and same imaging time and the hybrid adjustment of imagery with various sensor was conducted,which can be a big help for imagery ortho-rectifying in difficult area.
