摘要:
暗涵作为城镇排水系统的重要组成部分，在黑臭水体治理过程中对其进行排查和整治尤为关键。通过非接触式三维激光扫描技术解决了传统排查方式存在的暗涵定位精度低、二维成果形式单一和不满足GIS入库需求等问题。总结了三维激光扫描技术在城镇排水暗涵排查中的技术路线和方法。以深圳市宝安区大空港片区为例，介绍了三维激光扫描技术在暗涵排查中的应用。该技术能够快速获取暗涵内部的真实情况，获得精准的激光点云数据，进而实现暗涵的三维数字化。结果表明，采用三维激光扫描技术能够高效可靠地进行暗涵排查，成果丰富多样，精确度更高，在城镇黑臭水体治理中具有一定的推广应用价值。
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.
