| 摘 要： | 提出了利用机载LiDAR点云数据进行复杂平面建筑物重建的方法。首先,将提取出的建筑物点云聚类到不同的平面点集;然后,对各个平面点集进行平面拟合,采用平面相交确定平面边界,并解算出各平面边界角点的三维坐标,从而重建建筑物模型。某区域的机载LiDAR点云数据的实验结果表明,该方法能有效地重建出较复杂的平面建筑物。

| Abstract: | We present a method for complicated planar building reconstruction from airborne LiDAR point cloud data.Firstly,the extracted building points are clustered into the different plane point sets.Then,those points in point set are fitted into plane.Every planar boundary is decided by multi-planes intersecting.From every planar boundary and the height of ground around building,we can calculate the 3D coordinate of every corner point parameter in building reconstruction.The building model can be reconstructed usi... |
