Non-Contact Monitoring Throughout the Bridge Lifecycle

Haytham’s bridge monitoring solution uses the Online Visual Tracking System, passive targets, data transmission, and a cloud platform to monitor bridges from construction and load testing to long-term operation.

It continuously measures:

Deflection · 2D Displacement · Vibration · Modal Response

One system can monitor multiple points remotely, with no complex wiring on the bridge structure.

Non-contact · Multi-point · Fast deployment · Low disturbance · Remote monitoring

Non-Contact Visual Monitoring

The Online Visual Tracking System uses oblique-axis imaging and sub-pixel tracking to remotely measure displacement and deflection at multiple bridge locations.

▪ Image Acquisition

High-resolution cameras track passive targets on the bridge from a distance.

▪ Sub-Pixel Tracking

Advanced image tracking detects small displacement changes with high precision.

▪ Measurement Outputs

Deflection · 2D Displacement · Vibration Frequency · Modes · Impact Factor · Frequency-Domain Data

▪ Cloud Alerts

Data is transmitted via 4G/5G, Ethernet, or fiber, with automatic threshold alerts.

▪ Sensor Integration

Can integrate with strain, cable force, inclination, temperature, and humidity sensors.

From Monitoring to Early Warning

Visual Sensing → Data Transmission → Cloud Platform → Early Warning

▪ Visual Sensing

Online Visual Tracking System + passive targets for long-term outdoor monitoring.

▪ Data Transmission

Supports 4G/5G, Ethernet, and fiber, with mains or solar power options.

▪ Cloud Platform

Real-time dashboard, historical trends, report export, and multi-bridge management.

▪ Early Warning

Multi-level threshold alerts and automatic abnormal-event notifications.

Applications

Long-Term Bridge Monitoring

Continuous monitoring of deflection, displacement, and vibration during bridge operation.

Static & Dynamic Load Testing

Multi-point synchronized measurement of bridge deflection and dynamic response.

Construction Monitoring

Track structural deformation during cantilever construction, launching, rotation, and other construction stages.

Existing & Aging Bridges

Non-contact monitoring with passive, reversible targets and minimal disturbance to the structure.

Long-Span Bridges

Suitable for cable-stayed and suspension bridges, including large-area multi-point monitoring.

Emergency Inspection

Portable systems support rapid deployment for periodic inspection and post-event assessment.
