基于控制点规划影像库的遥感影像预处理系统的设计与实现

Design and Implementation of Remote Sensing Image Preprocessing System on Control Point Planning Image Library

在大尺度卫星影像的精几何预处理过程中,需要大量的控制点来实现影像的几何精纠正。为优化控制点布设的科学性,提高控制点的复用性,进一步提高卫星影像高级产品的生产效率,采用GIS和数据库技术,充分利用已有的高分辨率正射影像数据的基础上,设计了控制点影像库规划管理子系统,实现了对影像控制点数据进行布设规划、采集、管理及更新维护,并结合多源影像自动匹配技术,设计了卫星影像高级产品自动化生产子系统,实现了控制点数据提取、自动优化选取,提高了高级产品的自动化生产水平。

In the process of fine geometry pretreatment of large scale satellite images,a large number of control points are needed to realize the geometric correction of the image.To optimize the scientific layout of control points,improve the reusability of control points,further improve the production efficiency of satellite image advanced products,adopt GIS and database technology,make full use of the existing high-resolution orthophoto data base,design control point image library planning and management subsystem,realize the layout planning,collection,management and maintenance of image control point data,combined with multi-source image automatic matching technology,design satellite image advanced product automation production subsystem,to achieve the control point data extraction and automatic optimization selection,to improve the level of automation of advanced products.
