Rapid three-dimensional mapping moulding method for ground and underground pipe network

Abstract

The invention relates to a rapid three-dimensional mapping moulding method for ground and an underground pipe network, which comprises the following steps of: acquiring ground scene data and underground pipe data and respectively establishing three-dimensional model images of the ground and the underground pipe network; establishing the link between the ground and underground pipe network three-dimensional model images according to coordinates and storing the link into a database; carrying out rapid moulding in sections according to the moulding range of a rapid moulding machine to obtain underground pipe network sectioned distributing physical models; and splicing the sectioned distributing physical models to obtain an underground pipe network distributing physical model. The ground scene and an underground pipeline are combined and linked by the coordinates; people at different levels can vividly and visually find out the corresponding ground scene by a failure pipeline position and establish a maintenance scheme; similarly, an underground pipe network under a ground scene can be reformed and maintained; and the invention realizes the scientific management of urban infrastructure, saves the maintenance and construction cost, reduces the generating probability of accidents and improves the engineering safety degree and quality.

Description

technical field [0001] The invention relates to a three-dimensional surveying and mapping forming method, in particular to a rapid three-dimensional surveying and mapping forming method for ground and underground pipe networks. Background technique [0002] The urban underground pipe network is mainly composed of electricity, telecommunications, gas, tap water, rain (sewage) water pipes, etc. It is an important part of urban infrastructure, responsible for transmitting information and energy, and is the lifeline of the city. [0003] Since the reform and opening up, cities have developed rapidly. With the transformation of old urban areas and the construction of new urban areas, the volume of municipal infrastructure such as water pipes and sewage pipes has increased significantly; my country's vigorously developed telecommunications, gas, electricity, and urban centralized supply Heat, cable TV network, etc. have also increased the demand for underground pipelines; with the ...

AI Technical Summary

Problems solved by technology

[0007] 3. Various departments of the municipal department work independently, and the drawings of electric power, telecommunications, gas, tap water, and rain (sewage) water pipes are drawn separately, and there is no overall summary; even if there is, it is expensive

However, for the 3D visualization information established by this method, a large number of databases must first be established, and then modeled through the spatial data engine technology between the application program and the database management system, that is, ground and underground pipeline modeling; 2D and 3D data , must correspond to the 3D visualization level. On the computer display interface, the 3D pipe network view is easy to get lost. It is necessary to view the 2D modeling image and the 3D modeling image together to analyze clearly; in addition, the calculation of the pipe network is complicated, which is not conducive to construction Teams with different levels of education can understand
