Design And Implementation Of Indoor Pipe Network System In Buildings

With the continuous development of information technology in China’s urban management,3D modeling technology has been widely applied in the fields of digital city,urban planning,rail transit,campus,architecture,pipe network and so on.The application of 3D model is developing rapidly.However,the traditional 3D modeling method can not meet the requirements of integrated modeling for large buildings and indoor underground pipelines.With the rapid development of photogrammetry and lidar technology,the 3D modeling method based on multi-source geospatial data arises at the historic moment.This paper through the analysis of multi-source geospatial data acquisition experiment and data characteristics,multi-source geospatial data using the Tianjin Normal University built the large building indoor integration and 3D model,and then the research and application of 3D visualization model based on Skyline,get the following results:1.The acquisition of multi source geospatial data in the experimentation area is realized.2.Based on the acquired multi-source data,we built the indoor and outdoor integrated model of experimentation area building,and built an indoor and outdoor integrated 3D scene for the establishment of three-dimensional pipe network model.3.Based on the data standard of the pipe network,the construction of the data of the pipe network and the construction of the 3D modeling of the pipe network are carried out with the gymnasium of the experimentation area as the experimental object.4.According to the actual needs of the experimentation area management for the pipe network system,skyline was selected as the 3D visualization analysis platform,and the 3D visualization and application based on Skyline were studied.The functions such as visualization,query and measurement of pipeline network were realized.This paper proposes multi-source geospatial data based on the method of building indoor and outdoor and network integration of three-dimensional model of large buildings,can satisfy the requirement of integrated modeling and 3D modeling of indoor and outdoor precision and large buildings,and realize the 3D visualization,spatial measurement,spatial query and analysis functions of the information network profile based on 3D data visualization and application.
