Assessing road quality is a crucial task in infrastructure management. One of the most widely used indicators for this is the IRI — International Roughness Index. Traditionally, measuring IRI requires expensive equipment such as vehicle-mounted profilometers or laser sensors.

But what if I told you that we can calculate IRI using only a GoPro camera?

What Is IRI?

IRI is a standardized metric that represents the smoothness or roughness of a road surface, measured in meters per kilometer (m/km). The lower the IRI value, the smoother the road.
IRI is widely used by:

  • Government agencies (like public works departments) for road evaluations,
  • Contractors for quality assurance in road construction,
  • Transport or logistics startups for route optimization.

The Problem with Traditional IRI Measurement

Traditional IRI measurement tools include:

  • Vehicle-Mounted Profilometers – accurate but extremely expensive.
  • Accelerometer + GPS Setups – relatively cheaper but require careful calibration and integration. The issue? These tools are not accessible to everyone.

The Solution: GoPro + Algorithms
We explored the possibility of estimating IRI from road video recordings using affordable, widely available GoPro cameras.

Here’s how it works:
1. Record Road Footage
Mount a GoPro camera on your vehicle dashboard.
Record videos at a stable frame rate (ideally 30–60 fps).
2. Extract Road Features from Video
Frame-by-frame analysis using computer vision.
Our algorithm detects vibrations, surface texture, and visual oscillation.
3. Estimate IRI
Visual data is converted into numerical metrics.
Calibrated to match standard IRI values for reliable estimation.

Why It Matters
✅ Affordable
✅ Fast – Just record, upload, and get results in minutes.
✅ Flexible – Perfect for city walks, rural routes, or logistics planning.
✅ Web-based – Everything runs on a browser-based dashboard.
