多媒体技术在地铁隧道变形监测中的应用

摘要

This paper briefly introduces data acquisition approaches of tunnel deformation with the assistance of video camera, camera, georobot, 3-D laser scanner and other acquisition equipments of graph and image, proposes multimedia mathematical process flow of deformation monitoring data, and discusses the storage, query and calling, analysis and management methods of deformation monitoring data. The research shows that the application of modern multimedia data acquisition technology and database technology to establish tunnel deformation monitoring system can reflect the real-time deformation conditions of tunnel, and can provide forecasting and alarming information at any time by ways of number, curves, graph and image to ensure the safety of the tunnel.%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。
