| 摘 要： | 提出了基于顶点线性插值的建筑物群聚合的简易方法:首先通过插值加密建筑物轮廓线顶点,以最短邻近连线互不相交为原则,构建相邻建筑物轮廓线顶点之间的最短邻近连线;其次依据这些最短邻近连线自动确定相邻建筑物之间的聚合区域;最后按照渐进式方法聚合建筑物群,获取聚合后的新建筑物轮廓线,该方法还可以处理建筑物群的多边形存在相交和重叠空间拓扑关系的聚合问题。实验结果验证了该方法能有效聚合建筑物群,实用性强。

| Abstract: | To simplify the process and improve the efficiency of building group aggregation,we proposed a simple method of building group ag-gregation based on vertex linear interpolation.Firstly,we constructed the shortest adjacent connection lines under the principle of disjointafter in-terpolating dense vertices.Then,the aggregated parts between building group were automatically determined based on the shortest adjacent con-nection lines.Finally,building groups were aggregated progressively and new building outlines were obtained.This method can also aggregate building groups intersecting with each other.The experimentresults verify that the proposed method can effectively aggregate building group and has strong practicability. |
