多媒体技术在地铁隧道变形监测中的应用

简述了通过摄像机、照相机、测量机器人、三维激光扫描仪和其他图形图像采集设备采集隧道变形数据的方法,提出了多媒体变形监测数据的数学处理流程,讨论了多媒体变形监测数据的存储、查询调用、分析和管理方法.研究表明,采用现代多媒体数据采集技术和数据库技术建立隧道变形监测系统,能以数字、曲线、图形和图像等方式来反映隧道的实时变形情况并随时提供预报报警信息,确保了隧道安全.

Application of Multimedia Technology in Subway Tunnel Deformation Monitoring

This paper briefly introduces data acquisition approaches of tunnel deformation with the assistance of vid- eo camera, georobot, three - dimensional laser scanner and other acquisition equipments of graph and image. It proposes mathematical process flow of multimedia deformation monitoring data and discusses storage, query and calling, analysis and management methods of multimedia deformation monitoring data. The research shows that the application of modem multimedia data acquisition technology and database technology to establish tunnel deforma- tion monitoring system can reflect the real - time deformation conditions of tunnel and provide forecasting and alarm- ing information at any time by ways of number, curves, graph and image to ensure the safety of the tunnel.
