The Application of 3D Laser Scanning Technology in the Pipe Modeling of Petrochemical Enterprise

3D laser scanning technology was rapidly developed based on the advantages that rapidly, efficient, real-time, high-precision scanning point cloud data of the target surface, have been widely used in the field of the surveying and mapping.Combining with the engineering example, the paper discusses the application of 3D laser scanning technology in the pipe modeling of petrochemical enterprise, and puts forward the method of 3D model reconstruction that based on point cloud data.It includes the field reconnaissance survey, station layout, data acquisition, and then constraining the different point cloud data from several stations together.Finally, the 3D model of the pipeline can be reconstructed by the point cloud basing on the relevant software.
