Embodiment Construction
[0069] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.
[0070] In the following description, the use of suffixes such as “module”, “part” or “unit” used to indicate elements is only for the purpose of facilitating the description of the present invention, and has no specific meaning in itself. Therefore, "module", "part" or "unit" can be used in a mixed manner.
[0071] In order to solve the problem of using a total station and other auxiliary equipment to acquire three-dimensional data in the prior art, the scanner site needs to be set up and the target is arranged, and the station needs to be moved during data collection, which reduces work efficiency. The embodiment of the present invention provides A dynamic three-dimensional ...

The invention discloses a dynamic three-dimensional tunnel section deformation detection and analysis system, method and device. The method comprises the following steps that: controlling a scanner tocollect tunnel section information and rail section information to obtain a point cloud dataset; enabling the scanner to be positioned on the vehicle-mounted platform of a detection device; controlling an inertial navigator to obtain the three-dimensional attitude data of the detection device; controlling a driving motor to obtain the stroke data of the detection device; on the basis of a synchronization signal, carrying out data synchronization integration on the three-dimensional attitude data and the stroke data to generate positioning information; and according to the point cloud datasetand the positioning information, generating the three-dimensional spatial information dataset of the tunnel so as to carry out deformation analysis on the tunnel. Through the method, in a short maintenance period, the three-dimensional spatial information dataset is quickly obtained to carry out deformation analysis on the tunnel, and efficiency for obtaining data is improved. In addition, throughthe joint movement of the scanner and the vehicle-mounted platform, data collection accuracy is improved so as to realize the accurate evaluation of a tunnel safety state.
Description
Technical field [0001] The invention relates to the technical field of tunnel detection, and 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 the level of urbanization, traffic congestion has become a common problem in my country's major cities. The key to traffic congestion is the lack of urban road capacity, and the speed of road expansion cannot keep up with the increase in traffic volume. In order to solve the problem of traffic congestion, based on the principle of reducing the density of cars per unit area of roads, there are methods such as increasing road capacity, reducing road crossings, restricting vehicle entry, and developing public transportation systems. Among them, efficient underground rail public transportation is developed. The underground public transportation network extending in all dire...
