Automatic Construction and Visualization of 3D Models of Underground Pipe Network
With the development of underground municipal infrastructure survey,a large amount of underground pipeline survey data with different standards emerged.In order to improve the efficiency and utilization of pipeline survey data,based on the domestic GIS platform,taking the specification of Zhejiang underground municipal infrastructure database as an example,a method of automatic construction and visualization of 3D models of underground pipe network was proposed.Based on the data normalization inspection and automatic correction,the method completed the 3D topology networking,and then formulated the symbolization specification to realize the automatic symbolization of 3D pipeline network.It realized the automatic processing from the pipeline surveying data compliance with predefined specification to the modelling 3D topology pipeline network and provided a solution for the efficient processing of large quantities of standardized pipeline surveying data.
