Materials Mechanics
Monocular 3D Video Extensometer
In a tunnel safety monitoring project, we adopted the online visual tracker for long-term displacement and deformation monitoring of the tunnel structure. With multiple measurement heads, the system monitors the key structural points of the tunnel 24 hours a day without interruption, acquiring and analyzing the displacement and vibration data of the structure in real time.


Case highlights:
1. Real-time monitoring: the system can run continuously 7*24 hours, capturing the deformation, deflection and vibration of the tunnel structure in real time to ensure the timeliness of the monitoring data.
2. High-precision data: it can monitor the displacement changes at multiple positions simultaneously and output high-precision 2D (horizontal and vertical) displacement data, providing a scientific basis for structural safety during construction.



3. Intelligent early warning: the system has multiple warning thresholds. When the displacement or deformation of the tunnel structure exceeds the preset range, the warning mechanism is triggered automatically and the alarm information is pushed to the relevant technicians in real time, ensuring a timely response to risks.
4. Follow-up analysis: with the system's built-in video recording function, the structural behavior of the tunnel during key periods is recorded for further analysis and evaluation later.
Monitoring Results
The system effectively ensured the structural safety of the tunnel during construction and subsequent operation, successfully preventing a number of potential structural safety hazards through high-precision data and intelligent early warning, and providing reliable support for the smooth implementation of the project.
