Abstract

This paper details a complete hardware and software system designed to aid in the visual inspection and structural condition monitoring of railway tunnels. The system consists of two main components; an image acquisition system for data collection and an image processing software package for data analysis. The image acquisition system consists of an array of cameras with overlapping fields of view, a uniform lighting solution and a computer to control recording mounted on a rail trolley. The software package carries out operations such as image registration and stitching, 3D reconstruction and change detection. This software package is designed to generate and present image information in a manner which is most useful to structural examiners. The overall system aims to reduce the time taken to carry out visual inspection of tunnels while increasing the overall accuracy of inspections. Our preliminary findings indicate that the system directly benefits examiners when carrying out visual tunnel inspections.

一种用于铁路隧道视觉检测和结构状态监测的成像系统

本文详细介绍了一套完整的用于铁路隧道目视检测和结构状态监测的硬件和软件系统。该系统主要由两个部分组成;用于数据采集的图像采集系统和用于数据分析的图像处理软件包。图像采集系统由一组视场重叠的摄像机、一个统一的照明解决方案和一台安装在轨道小车上控制记录的计算机组成。该软件包可实现图像配准与拼接、三维重建、变化检测等操作。该软件包旨在以对结构检查员最有用的方式生成和呈现图像信息。整个系统旨在减少进行隧道目视检查所需的时间，同时提高检查的整体准确性。我们的初步研究结果显示，该系统在进行隧道目视检查时，可直接为检查员带来好处。
