Description
Technical Field
The application relates to a three-dimensional visual modeling method for an underground pipeline based on GIS and BIM, and belongs to the technical field of three-dimensional modeling of underground pipelines.
Background
Urban underground pipelines are an important component of urban infrastructure, which is the material basis upon which cities depend to survive and develop, known as the lifeline of cities. As the underground pipeline of the important infrastructure of the city, six pipelines including water supply, water discharge, fuel gas, heat, electric power, telecommunication pipelines and the like are respectively responsible for the work of energy transportation, dirt discharge, information transmission and the like, and are life line engineering for the development of city construction.
The underground pipeline has the greatest characteristics of strong concealment, difficult acquisition of spatial position information and low precision; the underground pipelines are crisscrossed vertically and horizontally, closely like a spider web, and the spatial relationship among various pipelines is complex. For the huge network of crisscross, a lot of data and charts of design, construction and completion exist in many cities, but due to various reasons such as long data time, quick city updating and the like, the data are incomplete, the related data have low precision or are inconsistent with the current situation, underground pipelines are easily broken or damaged during construction of facilities, and serious accidents such as water cut-off, communication interruption, sewage overflow and the like are caused. In addition, most of the urban data are managed by adopting a traditional manual mode, so that the urban data are low in efficiency and poor in scattered systematic property, manual drawing archiving is almost impossible for a changed area, drawing updating is slow, data collection is difficult, standards are not uniform, and pipeline maintenance is difficult. Therefore, with the development of urban planning construction, it is important to improve the management level of underground pipelines, and it is urgent to adopt informatization means to efficiently manage various underground professional pipelines, so as to meet the needs of school decision-making, management departments and construction units.
The three-dimensional visualization technology is one of key technologies of digital cities, is a dynamic visualization technology, and provides a brand new auxiliary technical means and method for planning, construction and management of cities. According to the Geographic Information (GIS) underground pipeline data detected in the field, three-dimensional visualization of the underground pipeline is realized, the current situation of the pipeline is restored, and space design and reconstruction updating are assisted. The three-dimensional visualization system displays underground pipeline information such as pipe diameter, burial depth, materials and categories by using a geographic information system technology, and can be displayed together with underground other infrastructures, underground garages, underground channels, subways and the like to realize inquiry and analysis related to space and topology.
The existing underground pipeline three-dimensional system construction is based on a database of pipeline detection, automatic pipeline modeling is carried out by using plug-in programs in the system, later data updating is convenient, and the three-dimensional model changes along with the database as long as the database changes. The system is a geographic information system, wherein the three-dimensional model can be applied to attribute inquiry, space analysis and the like. However, the model is not a built entity model, and is subjected to attribute hooking and long-short segmentation according to information data of a database, and can not be independently cut and divided. And the three-dimensional GIS entity model is automatically built according to the database and the drawing, and then is imported into a three-dimensional visualization system, wherein the three-dimensional model is GIS data. According to the underground pipeline model automatically built by the database, no entity model is built, and the underground pipeline model is inconvenient to use in later design and transformation, or a GIS entity model is built, but pipeline attribute information data is lacking.
