图像单点配准的开发与应用

Registering Image by One Control Point

针对目前退耕还林工程设计图只有一个控制点的现状,从提高图形数据录入速度出发,以先进实用为准则,以由单个控制点配准图像为目标,分析了地理信息系统中图像配准的原理和图像文件结构,开发出操作简单方便实用的单个控制点配准模图像模块,并提高了地理信息系统应用中的空间数据库的录入效率,取得了良好的效果。

A method of registering image by one control point is needed aiming at the fact that there is often one control point in the design drawings of returning farmland to forest project. Therefore, a simple program model is developed by analyzing the theory of registering image in geographic information system and the structure of image file in order to input graphic data rapidly. It is proved that the method could improve the efficiency of graphic data input, and good results were obtained.
