提出一种矢量图形边界特征点自动搜索方法，并在此基础上利用Voronoi图的点影响范围特性提出了一种基于Voronoi图的影像配准控制点自动搜索方法。将该方法所搜索到的特征点作为控制点，可以保证控制点获取的数量和分布均匀性。通过在矢量数据与影像数据配准应用及精度分析表明，提出的控制点自动搜索方法是有效可行的。

In this paper ,we present a method for automatically searching vector graphics bounda‐ry feature points ,and on the basis of the use of point impact characteristics of Voronoi diagram , the automatic search method of vector graphics boundary feature points is proposed .We used the feature points as the control points ,w hich could guarantee the quantity and distribution uniformi‐ty of control points .The application in the registrations between vector data and image data and the precision analysis showed that the proposed automatic search method for the ground control points was effective and feasible .
