Abstract

The invention discloses a dynamic three-dimensional tunnel section deformation detecting and analyzing system,method and device. The method comprises the steps that a scanner is controlled to collecttunnel section information and rail section information so as to acquire a point cloud data set; the scanner is located on a vehicle-mounted platform of a detecting device; an inertia navigator is controlled to acquire three-dimensional attitude data of the detecting device; a drive motor is controlled to acquire journey data of the detecting device; based on a synchronizing signal,data synchronism integration is carried out on the three-dimensional attitude data and the journey data,and locating information is generated; according to the point cloud data set and a tunnel three-dimensional space information data set generated by the locating information,deformation analysis is carried out on the tunnel. The dynamic three-dimensional tunnel section deformation detecting and analyzing system,method and device can quickly acquire the three-dimensional space information data set,carry out the deformation analysis on the tunnel,and improve the data acquiring efficiency in a shorter maintenance period. Through joint movement of the scanner and vehicle platform,data collecting accuracy is improved,therefore accurate estimation for tunnel safe states is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a dynamic three-dimensional tunnel section deformation detection and analysis system, method and device. Background technique [0002] With the development of my country's economy and the improvement of urbanization level, traffic congestion has become a common problem in major cities in my country. The key to traffic congestion lies in the insufficient capacity of urban roads, and the speed of road expansion cannot keep up with the speed of increasing traffic flow. In order to solve the problem of traffic congestion, based on the principle of reducing the vehicle density in the road per unit area, there are methods such as increasing road capacity, reducing road intersections, restricting vehicle entry, and developing public transportation systems. Among them, the development of efficient underground rail public transportation forms The well-connected underground publi...
