BridgePulse - AI and Drone technology for bridge health monitoring
In the pursuit of safe and sustainable infrastructure, continuous monitoring of bridges is a critical requirement. Traditional manual inspections often fall short in identifying micro-level structural issues such as early-stage cracks or rust, which can lead to catastrophic failures over time. To address these challenges, we developed BridgePulse, an innovative AI and drone-powered application that scans, analyzes, and monitors bridges across Andhra Pradesh.
This solution not only identifies surface level and subsurface structural issues such as cracks and rust but also provides accurate metrics like crack depth, width, and location via photogrammetry and mesh data. BridgePulse enables data comparison between scans taken at different times to track structural degradation, offering a powerful tool for maintenance teams, government agencies, and infrastructure planners.
Objectives
Develop a scalable solution for extensive bridge inspection.
1. Detect early signs of structural deterioration with precision.
2. Provide actionable data to improve maintenance planning and execution.
3. Enable periodic comparison to monitor degradation over time.
Methodology
BridgePulse revolutionizes the traditional approach by using drone-based scans combined with advanced AI and ML models to detect, visualize, and analyze bridge conditions. It pinpoints structural anomalies such as:
- Cracks (with depth and width estimation)
- Rust or corrosion in metal components
- Deviations from original design or previous scan data
- Crack and rust detection overlays
- Time-series comparison tools to monitor degradation

This solution not only identifies surface level and subsurface structural issues such as cracks and rust but also provides accurate metrics like crack depth, width, and location via photogrammetry and mesh data. BridgePulse enables data comparison between scans taken at different times to track structural degradation, offering a powerful tool for maintenance teams, government agencies, and infrastructure planners.
After deploying Sentra’s GNSS meters and edge gateways, our team gained continuous, high-fidelity visibility into structural behaviour. Their digital-twin dashboards and predictive alerts reduced unplanned maintenance, improved planning accuracy, and materially increased asset reliability — a true step-change for our operations.
