摘要
为保证隧道安全运营,要长期对其进行变形监测。隧道沉降变化是评估隧道安全的一个重要指标。文章利用激光准直性设计了隧道沉降监测装置系统,该系统由激光源组件和目标靶组成,系统首先采集激光打到目标靶上的光斑图像,再通过图像分割、形态学处理等获得光斑中心坐标,结合其他参数和初始测量信息,最终得出隧道沉降变化情况。实验检测和工程应用证明,该系统具有低成本、易于敷设、高精度等优点,能对隧道沉降实施有效监测。
In order to ensure the security of tunnel operation,the long-term structural deformation monitoring should be adopted. Tunnel settlement deformation is an important indicator to assess the safety of tunnel. This paper mainly introduces the monitoring system for tunnel settlement based on laser alignment,which is composed of laser modules and the target. The measurement purpose of this system has been realized through collecting video data of a laser spot,image segmentation,the morphological processing,the modules of surveying and initial parameter successively. Experimental results and engineering application show that this system is efficient in monitoring the structural deformation of tunnel,and has the advantages of low cost,easy laying and high precision as well.
