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。 A method to reconstruct complex plane buildings using onboard LiDAR point cloud data is proposed. Firstly, the extracted point clouds of buildings are clustered to different sets of plane points. Then, the plane sets of each plane are fitted by plane, the plane boundaries are determined by plane intersection, and the three-dimensional coordinates of the corner points of each plane are solved. Thus rebuilding the building model. The experimental results of airborne LiDAR point cloud data in a certain area show that this method can effectively reconstruct the complex plane structures.
