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

Abstract

The invention discloses a generation system and method using a three-dimensional model of an underground pipe network. The method includes: determining the spatial reference of the two-dimensional pipe network data; obtaining the origin position of the earth area data; dividing the earth area data into multiple grid areas according to the origin position and subdivision size; and uniquely identifying and coding each grid area; Generate the corresponding three-dimensional pipe network data from the two-dimensional pipe network data; obtain multiple tile codes corresponding to the multiple grid areas corresponding to the area to be drawn, and determine the three-dimensional pipe network data to be drawn; according to the tile code set and the to-be-drawn Three-dimensional pipe network data, draw a three-dimensional model of the underground pipe network; obtain the two-dimensional pipe network data to be updated; determine the corresponding tile code; determine the corresponding three-dimensional pipe network data to be updated; update the corresponding tile code in the three-dimensional underground pipe network model The data is used to obtain an updated three-dimensional model of the underground pipe network. The invention realizes the automatic and real-time generation and update of the three-dimensional model of the underground pipe network.

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
