摘要
综合图像处理和激光扫描两种技术优势,设计一套移动式隧道自动化检测系统,详细介绍了系统所达到的目标,给出了系统硬件设计方案,阐述了建立隧道扫描点云模型和隧道影像数据处理方法,通过对武汉大学珞珈山隧道进行数据采集和数据处理试验,结果表明,系统达到了预期效果,实现隧道内部表面三维点云和全景影像的快速自动化采集,可应用于隧道病害的检测分析。
A new mobile mapping system,combining the technical advantages of image processing and laser scanning,was developed for automated tunnel inspection.This paper explaines the purpose of the system,gives the system hardware design and describes the method of building a tunnel point cloud model and processing tunnel image data.After the trial of the Luojiashan Tunnel in Wuhan University,it turned out that the system achieved the desired effect which could realize the automatic acquisition of the 3Dpoint cloud and the panoramic image of the inner surface of the tunnel,and it could be applied to the detection and analysis of tunnel diseases.
