【摘要】：以機載LiDAR點云數(shù)據(jù)為研究對象,提出一種新的基于點云數(shù)據(jù)的多層建筑物三維輪廓模型高精度自動重建方法。在已完成建筑物結(jié)構(gòu)提取及輪廓規(guī)則化處理的基礎上,利用多層屋頂輪廓在水平投影面內(nèi)的相鄰關(guān)系,將各層屋頂中同等級屋頂?shù)南噜応P(guān)系概括為平行邊、不平行且不相交、相交3種相鄰形式,結(jié)合多層屋頂?shù)膶蛹壗Y(jié)構(gòu)信息對相鄰輪廓邊界進行一致性處理。實驗證明本文方法可以進一步消除多層建筑物各屋頂輪廓的規(guī)則化處理誤差,使相鄰輪廓邊界在水平投影面內(nèi)嚴格重合,同時重建后建筑物三維輪廓模型的正確性與完整性較高,拐點的定位精度優(yōu)于激光點平均間距。
[Abstract]:Taking airborne LiDAR point cloud data as the research object, a new high precision automatic reconstruction method for 3D contour model of multi-story buildings based on point cloud data is proposed. On the basis of the extraction of building structure and the regularization of the outline of the building, the contiguous relation of the multi-story roof contour in the horizontal projection plane is used to generalize the contiguous relation of the roof of the same grade in each floor as the parallel edge, which is not parallel and does not intersect. Three adjacent forms are intersected, and the contiguous contour boundary is processed in accordance with the hierarchical structure information of the multi-story roof. Experimental results show that the proposed method can further eliminate the regularization error of each roof profile of multi-storey buildings, and make the adjacent contour boundaries coincide strictly in the horizontal projection plane. At the same time, the 3D contour model of the reconstructed building has higher accuracy and integrity, and the accuracy of the inflexion is better than the average distance between laser points.
