- Under the US National Bridge Inspection Standards, how often do most highway bridges typically receive a routine inspection?
- Every 6 months
- Every 5 years
- Every 24 months
- Only after an accident
- Why is crack detection usually treated as a segmentation task instead of simple object detection?
- Practitioners need crack length and width, which requires pixel-level outlines
- Segmentation needs no training data
- Object detection cannot run on drones
- Cracks are always perfectly rectangular
- What is ground sampling distance?
- The distance a drone flies between batteries
- The depth ground-penetrating radar can reach
- The spacing between bridge piers
- The real-world size represented by one image pixel
- Which tools does the guide name for revealing deterioration inside concrete decks?
- Dashcams and GPS
- Ground-penetrating radar and infrared thermography
- Laser profilers and roughness indexes
- Strain gauges only
- Which of these is a common source of false positives for crack-detection models?
- Exposed rebar
- Potholes
- Stains, joints, shadows and formwork marks
- Corrosion on steel
- In this guide, what is a digital twin of a bridge?
- A model of the asset linked to its inspection history and sensor data
- A second bridge built next to the first
- A backup copy of the inspector's notes
- A drone that follows the inspector
- Why can't a crack image alone determine how serious the crack is?
- Cameras cannot capture cracks
- All cracks are equally dangerous
- Images are too large to analyze
- Seriousness depends on the crack's location, the type of member and the loads it carries
- Which technique helps with the severe class imbalance in crack segmentation?
- Using only color images
- Dice or focal loss functions
- Flying the drone higher
- Removing all images that contain cracks
