摘　　要：为了提取出地面建筑物的特征点与特征线,采用平面拟合算法提取特征点的方法,对算法进行了理论分析和实验验证,得到了建筑物的特征点与特征线,并构建出该建筑物的边界线框图。结果表明,利用地面3维激光扫描技术,扫描得到建筑物的点云数据,并对点云数据进行处理,最终能够提取出建筑物的边界线。这对数字城市建设具有重大的意义。For extracting feature points and feature lines of the building, this paper adopted plain fitting algorithm and theoretically analyzed and experimentally proved it, then obtained feature points and feature lines of the building and constructed boundary frame of it eventually. The result demonstrated that, which is significant for building digital city, with processing of point cloud acquired by terrestrial laser scanning technique, boundaries of buildings can be extracted.
