Rock mass tunnel face analysis feedback integrated system based on three-dimensional laser scanning

Abstract

The invention relates to a rock mass tunnel face analysis feedback integrated system based on three-dimensional laser scanning. The system comprises a face three-dimensional laser scanning device which uses a three-dimensional laser scanning technology to record three-dimensional point cloud data and transmits the data out, a background non-continuous numerical value analysis device which carries out three-dimensional reconstruction of the point cloud data and automatic information extraction, establishes and analyzes a three-dimensional non-continuous numerical value model, and feeds back the analysis result to a mobile terminal located at the construction site through a data remote transmission module, and a rock tunnel data remote transmission device which is connected with the face three-dimensional laser scanning device, the mobile terminal and the background non-continuous numerical value analysis device and is used for forwarding data. Compared with the prior art, the system provided by the invention realizes refined and rapid acquisition, analysis and feedback of the information on the face of a rock mass tunnel, and can effectively guarantee the construction quality, safety and progress.

Description

technical field [0001] The invention relates to the technical field of rock tunnel engineering, in particular to an integrated system for rock tunnel face analysis and feedback based on three-dimensional laser scanning. Background technique [0002] Structural planes exist widely in rock mass and have a significant impact on the mechanical parameters and stability of rock mass. The refinement and rapid acquisition, analysis and feedback of important structural surface information in the tunnel face of rock mass can directly affect the quality, safety and progress of tunnel construction. At present, the collection of face information is mainly through visual observation and manual recording. This method has poor accuracy and is easily affected by environmental and personnel subjective factors. The collected information needs to be transmitted to the back end of the numerical analysis to quickly analyze and get the results back to the site, but currently there is a lack of a ...

However, only the information on the two-dimensional surface of the joint can be obtained, and the camera device needs to be assisted by a lighting device, which is easily affected by the site environment

[0005] The existing technology similar to the present invention can only obtain two-dimensional image information of the face surface, is easily affected by the site environment, and only has the functions of information collection and joint recognition. There is still a big gap
