- Abstract:
- As an important part of urban drainage system, culverts’ investigation and regulation are particularly important in the treatment of black and odorous water bodies. The non-contact three-dimensional (3D) laser scanning technology solves the problems of traditional investigation method, such as low position accuracy, single 2D output form, and not meeting GIS database requirements. The technical approach and method of 3D laser scanning technology in urban drainage culvert investigation are summarized. With the example of Dakonggang area in Bao’an District of Shenzhen, the application of 3D laser scanning technology in culvert investigation is introduced. This technology can quickly obtain the true situation inside culverts, obtain accurate laser point cloud data, and achieve the 3D digitization of culverts. The results show that using the 3D laser scanning technology can yield more efficient and reliable culvert investigation, with richer and more diverse output, and higher accuracy. Therefore, the technology has broad application value in the treatment of urban black and odorous water bodies.
