摘要: 隧道掘进机(Tunnel boring machine,TBM)被广泛地运用于隧道施工中。隧道的变形是影响TBM施工安全的主要因素之一,过大的隧道变形会引起隧道塌方、TBM卡机等事故,影响施工进度,威胁施工人员的生命安全。针对TBM施工情况,介绍基于视觉辅助的隧道轮廓监测系统。采用荧光涂料设计人工标志点,单目视觉检测目标,云台驱动激光位移传感器瞄准目标。基于极坐标测量原理,获取目标点三维坐标。为进一步提高测量效率,提出基于半定规划的双目视觉系统辅助测量方案。试验结果表明系统的精度可达1 mm并具有较高的测量效率。

Abstract: Tunnel boring machine (TBM) has been widely applied in tunnel construction. The deformation of tunnel is one of the major concerns in TBM construction project. Major deformation may cause tunnel landslide or TBM jam, influence the construction schedule and threaten the safety of the constructors. A tunnel deformation monitoring system based on vision assistant in TBM construction is proposed. Artificial target points are designed by using fluorescent coating. Targets are detected by using monocular vision and aimed by using a Pan-tilt platform. The three-dimensional coordinates of the targets are obtained based on the principal of polar coordinates of the Pan-tilt platform using laser distance measurement. The efficiency of measuring is further improved by using a binocular vision system assistant measurement based on semi-definite programming method. Experiments show the precision of the system can be up to 1mm with good efficiency.

Key words: laser, TBM, tunnel deformation, vision
