Abstract: Building information modeling (BIM) has been widely used to improve the management efficiency of complex pipeline systems. However, BIM modeling of existing oil pipelines often relies on design drawings or field mapping, which is time-consuming and laborious. Therefore, a BIM reconstruction method for oil pipeline based on RGB-D depth image and LiDAR point cloud data is proposed. Based on the rich semantic information provided by RGB-D image and the precise geometric information of LiDAR point cloud, the RGB image collected by depth camera is segmced to generate 3D semantic map. Then data fusion is realized by point cloud rough matching and precise matching. Finally, the BIM model making method of different structure pipeline components is given. The experimental results show that compared with the previous BIM reconstruction methods of pipelines, this method is more accurate and efficient, which is helpful for petroleum enterprises to implement information management for the metering and transfer stations containing complex pipelines.
