Abstract

The invention discloses a 3D automatic modeling and scheduling rendering method for an integrated pipe network, and relates to the technical field of 3D model building. The method comprises the following steps: data reading; layer creating; cutting scheduling; automatic pipeline modeling; automatic pipe point modeling; and automatic pipe network building. The technical problems, such as 2D-3D integrated management based on underground pipe network data in geographic information, spatial data organizing and rendering, and automatic 3D pipe network building according to 2D data, can be solved effectively. The access efficiency to pipe network information in a 3D scene is improved. The level of unified display, management and analysis of multiple underground pipe network systems having different attributes is improved. An important basis is provided for the acquisition and construction scheme of underground pipe network spatial information in urban construction, especially in smart city building in the future. The rapid development of urban construction leads to large-scale development and utilization of urban underground space resources.

Description

technical field [0001] The invention relates to the technical field of three-dimensional model construction, in particular to a technical problem that can effectively solve the two-dimensional and three-dimensional integrated management of underground pipe network data based on geographic information, spatial data organization and scheduling, automatic construction and rendering of three-dimensional pipe network, and the like. By using 2D pipeline data to automatically create 3D models, the management level of 2D and 3D integration is improved, the workload of 3D pipeline data maintenance is greatly reduced, and the display effect of pipeline data is improved. By adopting a dynamic scheduling method for the pipe points and pipelines in the underground pipeline network, the equipment memory is effectively used to support the loading of massive pipeline data, and the data loading speed is improved; the paging index mechanism is adopted to quickly schedule and display pipeline dat...

Problems solved by technology

The three-dimensional modeling of the pipe network is carried out through the three-dimensional modeling software. This modeling method first needs to import the central axis of the pipe network entity into the computer-aided design software, and then use the human-computer interaction technology to render the points and lines in the three-dimensional software. The method generates a 3D model of the pipeline and performs corresponding processing on the pipeline interface. The disadvantage of this method is that the precise positioning of the pipeline elements is not strong, it requires a lot of manual intervention, and the modeling speed is slow

[0013] At present, there is no perfect method that can effectively solve technical problems such as two-dimensional and three-dimensional integrated management of underground pipe network data based on geographic information, spatial data organization, and automatic construction of underground three-dimensional pipe network.
