摘要
地面控制点的选取是遥感影像几何纠正中的重要环节。控制点的数量、分布和精度直接影响影像纠正的精度和质量。本文较为系统地总结了控制点选取的诸多要素及注意事项,并对GCP选取的自动化技术进行了探索和实践。
The selection of ground control points (GCP) is an important process in geometry rectification of remote sensing image. The number, distribution and accuracy of GCP could affect the accuracy and quality of image rectification directly. This article has summarized the factors and principles of selection of GCP and some research and practice about the automatic technique had been done.
