A Code-Conforming Computer Vision Framework for Visual Inspection of Reinforced and Prestressed Concrete Bridges
This paper presents VIADUCT, an AI-powered framework for visual inspection of concrete bridges, using YOLOv8n for damage detection. It focuses on code-compliant defect taxonomy, multimodal attention mechanisms (SAM, U-Net) for segmentation, and a user-friendly GUI to assist inspectors. The system aims to enhance efficiency and objectivity in bridge maintenance by identifying a wide range of defects, even in challenging wide-angle images, and integrating with existing regulatory frameworks.
The Enterprise Impact
VIADUCT provides a code-conforming, AI-assisted inspection framework that supports inspectors in identifying a wide range of bridge defects, enhancing safety assessments and maintenance planning according to national guidelines.

Decision Support (Inspection Aid)
| Feature | U-Net | SAM |
|---|---|---|
| Inference Speed | Significantly faster, suitable for real-time/batch | Slower, resource-intensive for high-res |
| Output Determinism | Consistent, automated segmentation | Interactive, point-based user guidance |
| Domain Specificity | Trained on bridge images, better generalization | General purpose, high precision for user-guided refinement |
| Visual Context | Gaussian blur preserves context and reduces discontinuity | Traditional masking (implied by SAM's precise cuts) |
Real-World Application: Bridge #1 Detection
An example demonstrating the model's ability to identify predominant deterioration mechanisms on Bridge #1, comparing ground truth annotations with YOLO predictions.
Highlights:
- Correctly identifies dominant defects like washed-out concrete and drainage streaks.
- Challenges with small-scale, localized defects such as corroded reinforcement.
- Demonstrates effectiveness in identifying prevailing deterioration mechanisms at the image level.
Outcome: The model proves capable of supporting inspectors by accurately classifying major defect types, even if precise localization of minor defects remains challenging in complex backgrounds.
