A method and system for generating a three-dimensional model of an underground pipe network

Abstract

The invention discloses a method and a system for generating an underground pipe network three-dimensional model. The method comprises steps that spatial reference of the two-dimensional pipe network data is determined; an origin position of the earth area data is acquired; according to the origin position and dissection dimensions, the earth area data is divided into multiple grid areas; unique identification coding for each grid area is carried out; the three-dimensional pipe network data corresponding to the two-dimensional pipe network data is generated; multiple tile codes corresponding to multiple grid areas corresponding to a to-be-drafted area are acquired, and the to-be-drafted three-dimensional pipe network data is determined; the underground pipe network three-dimensional model is drafted according to a tile code set and the to-be-drafted three-dimensional pipe network data; the to-be-updated two-dimensional pipe network data is acquired; corresponding tile codes are determined; the corresponding to-be-updated three-dimensional pipe network data is determined; the data corresponding to the tile codes of the pipe network three-dimensional model is updated, and the updated underground pipe network three-dimensional model is acquired. Through the method, the underground pipe network three-dimensional model can be automatically and timely generated and updated.

Description

technical field [0001] The invention relates to the technical field of underground pipe network management, in particular to a method and system for generating a three-dimensional model of an underground pipe network. Background technique [0002] In recent years, with the frequent occurrence of domestic urban underground pipe network accidents, all walks of life have paid more and more attention to the safety of urban underground pipe networks. How to ensure the safety of urban underground pipe networks has become an urgent problem for governments at all levels to solve. Compared with two-dimensional display technology, three-dimensional simulation technology has the characteristics of truly reflecting the distribution, position, and shape of objects in real space. It is used in the field of urban underground pipe networks with complex distribution and various types, which will provide protection for urban underground pipe networks. provide strong support for safety.

Problems solved by technology

The 3D model of the underground pipe network is generally generated in a pre-generated manner, that is, the 3D model of the underground pipe network is generated in advance through the program, and then directly loaded and called when the application system is running; when there is a 2D 3D pipe network data update in a certain geographical area In this case, delete all the original 3D model data of the pipe network in the area, and then pre-generate the 3D model of all the updated 2D and 3D pipe network data in the area, and then reload and call it when the application system is running. Not only is the efficiency low, it is not conducive to the update of the 3D model of the underground pipe network, but also the corresponding 3D pipe network model in the application system can also be updated automatically and in real time after the 2D pipe network data is updated
