三维激光扫描仪在排水管网测量中的应用
- Title:
- Application of 3D Laser Scanner in Drainage Pipe Network Measurement
- 摘要:
- 随着城市地下管线信息化管理、表达和应用从二维向三维延伸，可利用三维激光扫描及点云建模技术开展三维管网建设工作。以某排水管网为研究案例，采用架站式激光扫描仪和移动式激光扫描仪对排水管网进行扫描，主要介绍了两种扫描方式的技术要点及优缺点，最后对管网扫描精度进行了分析。结果表明，采用三维激光扫描仪测量排水管网，可以解决传统二维管线空间关系不明晰、显示效果不直观等问题，此次研究可为未来大规模开展管网激光扫描工作提供经验。
- Abstract:
- With the extension of urban underground pipeline information management, expression and application from two-dimension to three-dimension, 3D laser scanning and point cloud modeling technology can be used to carry out 3D pipe network construction. Taking a drainage pipe network as a case, this paper studies the scanning of drainage pipe by using stand-up laser scanner and mobile laser scanner, mainly introduces the technical points, advantages and disadvantages of the two scanning methods, and finally analyzes the scanning accuracy of the pipe network. The results show that using 3D laser scanner to measure the drainage pipe network can solve the problems of unclear spatial relationship and unintuitive display effect of traditional 2D pipeline, which can provide experience for future large-scale pipeline network laser scanning work.
