| 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。针对人工选取控制点的缺陷,根据控制点数据的特点提出了控制点属性数据和图像数据的一体化存储管理方案;设计了控制点库查询检索、匹配选点的使用流程;实现了一个控制点影像数据库的应用系统。系统的使用效果达到预期设想,大大提高了选点精度和效率。对控制点数据进行建库管理可以充分利用已有控制点成果,并能提高选点效率和精度。

| Abstract: | The selection of ground control points(GCP) is an important process in geometry rectification of remote sensing imagery.Based on the study about disadvantage of manual GCP selection and the character of GCP data,the integrated storage management scheme for attribute data and image data of GCP is proposed.Furthermore,a pipeline of the query,index,image matching and selecting GCP are designed in the article,and a system of GCP image database has been implemented.The exploitation effect of system,which improves the accuracy and efficiency of point selection,conforms to expectation.The management of GCP data by database can make full use of GCP date,and improve the accuracy and efficiency of GCP selection. |
