摘要(Abstract)：

提取建筑立面中窗户等非墙面元素的边界特征是利用点云数据进行建筑物精细化建模的难点。针对该问题，提出一种基于模板匹配的建筑物激光点云立面几何特征提取方法。首先采用RANSAC算法粗分割建筑物立面，通过双向DBSCAN算法提取墙面点云，并依据墙面点云提取墙面边界和分离窗户点云；其次，对窗户点云进行欧式聚类和矩形拟合分类；然后对窗户的特征凸包点内插获得窗户边界模板点云；最后利用模板匹配方法获取完整的建筑物立面窗户点云边界，并获得整体建筑物立面边界点云数据。实验结果表明，该方法可以精确提取建筑物墙面点云边界，补全部分边界缺失的窗户轮廓边界点云，满足建筑物精细化建模的需求。
