移动式三维激光SLAM技术在暗涵排查中的应用

暗涵是城市排水系统中不可缺少的重要设施,暗涵雨污合流导致河流水系污染严重,年久失修易出现淤堵、渗漏、塌陷等病害。移动式三维激光SLAM技术不仅能采集暗涵三维空间数据,建立1∶1的模型,还可以获取暗涵的空间地理信息,达到探测测量的效果。利用点云数据模型,还能完成排放口的探测、箱涵结构检测、涵内环境扫描等一系列工作,为生态文明建设提供可靠的技术保障。

The hidden culvert is an indispensable important facility in the urban drainage system.The confluence of rain and pollution in the hidden culvert leads to serious pollution of the river system,and diseases such as blockage,leakage and collapse are easy to occur after falling into disrepair.The mobile 3D laser SLAM technology can not only collect the 3D spatial data of the hidden culvert and establish the 1:1 model,but also obtain the spatial geographic information of the hidden culvert,so as to achieve the effect of detection and measurement.Using the point cloud data model,we can also complete a series of work,such as discharge port detection,box culvert structure detection,environment scanning and so on,so as to provide reliable technical guarantee for the construction of ecological civilization.
