Applications of Multimedia Technology in Deformation Monitoring of Subway Tunnel

This paper briefly introduces data acquisition approaches of tunnel deformation with the assistance of video camera, camera, georobot, three-dimensional laser scanner and other acquisition equipments of graph and image, 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 modern multimedia data acquisition technology and database technology to establish tunnel deformation monitoring system can reflect the real-time deformation conditions of tunnel and provide forecasting and alarming information at any time by ways of number, curves, graph and image to ensure the safety of the tunnel.
