摘　　要：本文在对1∶500地形图与其自身影像图配准误差分析的基础上,提出了一种基于最小二乘法的区域整体最优匹配选取控制点的方法,主要针对在GIS中从地形图上选取控制点来配准影像图。本文在对新方法进行了论述,并通过对浙江温州地区一幅栅格图像与1∶500 GIS数据进行配准控制点选择实验,对比传统方法它能够克服由于影像分辨率和人工对影像刺点所带来的系统误差,大幅度提高配准精度,使得不同空间尺度下的地图数据实现精确配准。In this paper, the author presented a control point selection method based on the least squares analysis of regional integral optimal matching, which mainly aims to select the control points required for image registration in GIS. This method could overcome systematic errors caused by image resolution and pricking point in the image artificial. The control point selection experiment, which uses a grid map and 1：500 topographic maps in Wenzhou, Zhejiang was presented. The final results verified that the registration accuracy could be greatly improved by this method, allowing accurate registration of map data of different spatial scales.
