摘要/Abstract

摘要： 地铁隧道随着运营时间的增长,因地质条件、自然灾害、施工质量、周边环境等复杂因素的存在,易发生衬砌剥落、裂纹、渗漏水等常见病害。目前检查手段主要靠人工目视,受隧道断面、天窗时间、照明条件等各项因素的限制,难以高精度、高效率地完善隧道检查。本文设计了基于车载式多目相机的地铁隧道病害检测系统,以专用检测车为载体平台,集成线阵相机、光源、电源等硬件设施。首先,检测车沿着轨道电动匀速前进,并在垂直方向上作二维扫描,采集隧道表观高分辨率彩色影像数据;然后,基于拼接后的影像,判断、识别隧道裂缝、渗漏、剥落等病害信息。相对于传统手段,基于车载式线阵相机的检测系统可对隧道空间信息实现全覆盖快速采集,且便于数字化存档及病害发展态势分析。

Abstract: As the operation time of subway tunnels increases,common diseases such as lining peeling,cracks,and water leakage are prone to occur due to complex factors such as geological conditions,natural disasters,construction quality,and surrounding environment.At present,the inspection method mainly relies on manual visual inspection,which is limited by various factors such as tunnel section,skylight time,and lighting conditions,making it difficult to improve tunnel inspection with high precision and efficiency.A subway tunnel disease detection system based on a vehicle-mounted multi-eye camera is designed.A special inspection vehicle is used as a carrier platform,and hardware facilities such as linear array cameras,light sources,and power supplies are integrated.The inspection vehicle is used to move along the track at a uniform speed and perform 2D scanning in the vertical direction to collect high-resolution color image data of the tunnel surface.Based on the spliced images,the information of tunnel cracks,leakage,peeling,and other diseases can be judged and identified.Compared with traditional methods,the detection system based on vehicle-mounted linear array cameras can achieve full coverage and rapid collection of tunnel space information,and is convenient for digital archiving and disease development trend analysis.
