Establishment method for urban three-dimensional visualization underground pipeline system based on Cesium

Abstract

The invention discloses an establishment method for an urban three-dimensional visualization underground pipeline system based on Cesium, and relates to the field of virtual three-dimensional pipelines. The method comprises the following steps: S001, acquiring above-ground and underground data information of an urban building group by using a GIS technology, and perfecting an urban geomorphological database; S002, using a GPS system and a pipeline positioning system to complete data collection of pipeline under construction and pipeline to be constructed, and perfecting an underground pipelinenetwork database; S003, using a remote sensing image technology and a DEM technology, combined with the urban geomorphological database and the underground pipeline network database, to generate 2.5-dimensional topographic landscape map data. The method provides convenience for people to maintain underground pipelines and future urban layout by collecting urban geography and geomorphology information and urban network management data information, and the remote sensing image technology, the DEM technology and the Cesium are used to build an urban three-dimensional model and an underground pipeline network model.

Description

technical field [0001] The invention belongs to the field of virtual three-dimensional pipelines, in particular to a method for establishing an urban three-dimensional visualized underground pipeline system based on Cesium. Background technique [0002] With the rapid development of my country's economy, the scale of cities is also constantly expanding, and the laying of urban underground pipe networks is also increasing. Urban underground pipe networks are responsible for the tasks of information transmission, energy delivery, water supply and drainage, etc. Therefore, it is known as the lifeline of the city. However, with the rapid development of the city, the material flow and energy flow in the city gradually increase, which makes the spatial distribution of urban underground pipelines more and more narrow. Therefore, it is of great significance to establish a 3D model of the city and underground pipeline network. [0003] The traditional underground professional pipelin...
