Study on the automatic generation and visualization of three-dimensional pipeline oriented for smart city

Smart city, as an advanced form of new-generation urban information based on internet of things and cloud computing, has become the latest concept of urban construction, striving to make the city life much more intelligent with information and communication technology. As a significant part of construction, wall pipelines cover various aspects, including electricity, water supply and pollution discharge. In this paper, the three-dimensional model was automatically generated by the traditional two-dimensional plane graph, and the interaction and real-time modeling for three-dimensional scene were accomplished with virtual roaming technology, which can observe the location of wall pipeline in the most direct way and provide convenience for managing the pipeline information of smart city.
