The Hexagon MyMo portable radar-vision fusion monitoring system features a lightweight, non-contact design, allowing a single operator to rapidly deploy the unit and simultaneously capture displacement and vibration frequency data. Beyond its use for historic structures and tunnels, the system is highly versatile, making it suitable for applications such as bridge and slope monitoring.
Leveraging the core strengths of quantitative radar monitoring and visual geo-registration, the system enables the integration of monitoring data with real-world imagery, facilitates the tracing of deformation anomalies, and provides safety early warnings.
Bridge Soffit Monitoring | Precise Registration of Monitoring Points on Real-World Imagery
A single operator can set up the system in approximately 10 minutes and select specific monitoring points directly on the live video feed. Displacement and vibration data are displayed in real-time, with the capability to resolve these into vertical or horizontal components. Compared to traditional methods, this streamlines the workflow, enabling timely assessment of structural conditions and providing essential data for load-bearing capacity evaluations and modal analysis.
Through non-contact monitoring, users can view displacement and vibration data—including deflections in the bridge soffit—in real-time via a tablet.
Bridge Cable Vibration Monitoring | Simultaneous Multi-Point, Multi-Cable Assessment
There is no need to attach targets or sensors to the cables; the system can capture data from multiple points across several cables simultaneously. With a sampling rate of up to 400Hz and an integrated accelerometer, it calculates cable amplitudes and vibration frequencies for various modes in real-time. This supports the assessment of cable tension and the overall structural health of the bridge, enhancing both monitoring efficiency and safety.
Emergency Slope Monitoring | Intuitive Tracing of Deformation Anomalies
The lightweight design allows for flexible deployment in emergency scenarios. Utilizing real-world mapping capabilities, users can pinpoint areas of concern directly on the visual feed, accelerating the identification of hazards and on-site verification. The system’s radar-based 3D reconstruction generates a point cloud model of the site, while the onboard software enables real-time observation of slope deformation.
The system supports remote data viewing, analysis, and early warning alerts. It provides critical data for emergency response and rescue operations, enabling the proactive anticipation of disasters and rapid intervention to safeguard lives and property. Key Advantages
Innovative fusion of MIMO 2D-array radar and binocular vision: Monitoring results are registered and overlaid onto real-world imagery, ensuring that what you see is exactly what is being measured.
Comprehensive static and dynamic monitoring: A single unit handles both slow-moving, quasi-static displacement observation and high-frequency dynamic signal acquisition—ideal for long-term stability monitoring, vibration analysis, deflection measurement, and dynamic load testing.
Onboard edge computing: Monitoring results are presented in real time. Data processing and analysis are performed locally on the device, eliminating the need for an external computer and enabling direct output of results in the field.
All-weather field operation: Designed for outdoor use, the system withstands significant temperature fluctuations. It supports battery power and various data transmission methods, ensuring continuous data acquisition even in challenging environments such as those with heavy dust or rainfall.
The Hexagon MyMo portable radar-vision fusion monitoring system provides a convenient, efficient, and precise solution for structural health monitoring and emergency assessment of geological hazards, establishing a robust safety line for infrastructure operations, maintenance, and disaster response.
