隧道是铁路运营的重要设施,隧道沉降控制在铁路运营安全中起着至关重要的作用。以京广高铁为背景,在研究现有的静力水准远程自动化监测方案和激光远程测量监测方案的基础上,利用激光测量技术与计算机技术,提出了一种新的路基沉降监测方案——机器视觉监测方案。该方案使用片光源与图像识别技术解决了监测系统精度与成本的矛盾,能对高速铁路隧道路基沉降变形进行准确的监测。 Tunnels are important facilities for railway operations. Tunnel subsidence control plays a crucial role in the safety of railway operations. Based on the Beijing-Guangzhou high-speed railway, based on the research of existing static level remote monitoring program and laser remote measurement monitoring program, a new subgrade settlement monitoring program is proposed based on laser measurement technology and computer technology Visual monitoring program. The program uses the tablet light source and image recognition technology to solve the conflict between the accuracy and the cost of the monitoring system and can accurately monitor the subsidence and deformation of high speed railway tunnel subgrade.
