| Abstract: | According to the efficient modeling demand of mass well chambers in the information construction of un-derground pipeline, the well chamber classification method of underground pipeline is proposed. Based on the clas-sification, the three-dimensional data model and the automatic modeling method of the true three-dimensional well chamber are designed and realized. And the contrast experiments on efficiency and effectiveness for this method and the traditional 3DMax modeling method are done. The experiments show that automatic modeling method of true three-dimensional well chamber can greatly improve the efficiency and accuracy of well chamber three-dimen-sional modeling. |
