Pipeline network is composed of crisscross sewage pipes, water supply pipes, fire-fighting pipes, power industrial pipes, etc. it is an important part of urban infrastructure and regarded as the lifeline of the city. Unified planning, design, construction and management of urban underground pipe network is an important infrastructure and "lifeline" to ensure urban operation.
To carry out visual management of pipeline network, monitor the operation status and loss degree of urban pipeline network, feedback the operation status of equipment, and provide accurate, intuitive and efficient reference for the planning, utilization and scientific layout of underground pipeline resources, the 3D visualization model of pipe network geographic information system came into being, which is the basis for 3D spatial analysis of large and complex urban pipe network system, and provides scientific decision-making, Economic scheduling. It is necessary to establish a 3D model of the pipeline network.
The 3D model which built by 3D laser scanning technology breaks through the traditional data acquisition method of discrete points and creates a surface-based data acquisition method. It can obtain the 3D coordinates of the measured object surface in a large area and high resolution, and can quickly collect spatial point information, as well as color information, object reflectivity and other information. It makes up for the limitation of the traditional 2D information on the interaction of underground space, and is especially suitable for the measurement and modeling of complex above ground pipelines and underground pipe corridors in pipe network engineering to meet their high-definition, dynamic and 3D management needs.
EasyScan series can be worked actively. In the dark environment, the spatial position information of the target can still be obtained, and the 3D point cloud data can intuitively reflect the internal structure of the whole space. In the practical application of pipeline network engineering, no matter how complex the observation object or environment is, the massive point cloud data obtained by 3D laser scanning technology can be truly and restored to the real situation after later in-house processing, providing an information platform for the maintenance, monitoring and transformation of pipeline network and equipment. The data obtained by 3D laser scanning technology is accurate, comprehensive, easy to operate, high efficiency, and can avoid potential safety hazards, which can well meet the needs of pipeline network engineering.
