利用航空影像、点云数据和矢量图进行简单房屋三维重建方法研究

An Approach on Building Reconstruction from Images,Data Clouds and Vector Maps

采用航空影像、点云数据和矢量图进行房屋的三维重建。该方法从矢量图和三维点云数据提供的房屋高度信息中自动获取房屋模型参数的初始值,利用矢量和影像匹配技术、最小二乘平差算法实现平顶房、人字形简单房屋的自动三维重建。试验数据证明,该方法能较好地实现房屋的点云数据分割和平顶房、人字形简单房屋的几何模型自动重建。

This paper presents an approach on building reconstruction from images, point clouds and vector maps. The proposed method gets initial parameters of building models from vector maps and point clouds. The parameters of building models are refined by vector and image matching, least squares adjustment. The approach is tested to be effective on point clouds segment and building models reconstruction.
