A method and a system for automatically collecting multiple information of a tunnel during construction period are provided. A detection point and a detection line are formed by projecting a light source on the inner wall of the tunnel, and then the pixel position changes of the areas where the detection point and the detection line are located in different time periods are recorded by a measuring camera, and the detection point and the detection line are integrated and corrected with tunnel point cloud data as a reference standard to form an accurate four-dimensional model of the tunnel.

Method and system for automatically collecting multiple information of tunnel during construction period

Provided are a method and a device for real-time monitoring of tunnel deformation. The monitoring method includes: S, erecting a plurality of structured light sources in an unstable area to be monitored of a tunnel structure, and erecting a monitoring terminal in a relatively stable region of the tunnel structure, where the monitoring terminal may communicate with the plurality of structured light sources; S, observing all structured lights in the unstable area of the tunnel structure and obtaining structured light curves in real time by the monitoring terminal; S, analyzing imaging changes of the structured lights, detecting deformation degrees and offset distances of the tunnel in real time, and monitoring the diseases such as settlement, convergence of a single-section of the tunnel and integral settlement of a multi-section of the tunnel by the data processing unit.
