1. What are the pain points of traditional bridge inspection vehicles?
Traditional bridge inspection vehicles have three pain points: first, high cost — full-bridge scanning requires large labor and equipment investment; second, dangerous operations — personnel must work at height beneath the bridge deck; third, limited coverage — areas such as bridge bottoms and box girders are hard to reach fully, leading to high miss rates.
2. Core advantages of the drone solution
| Comparison dimension | Traditional bridge inspection vehicle | Intelligent drone inspection |
|---|---|---|
| Blind spot coverage | Bridge bottom, high piers hard to reach | Full-structure coverage with no dead zones |
| Operational risk | High-altitude, edge operations high risk | Non-contact, zero personnel risk |
| Operational efficiency | Several days per bridge | Full-bridge capture in hours |
| Data traceability | Paper records hard to trace | Full imagery comparable year over year |
3. How is data value realized?
The drone automatically collects full-bridge data along preset routes, relies on AI to automatically detect defects and map them onto the 3D model, supports multi-period comparison to observe defect progression, and provides complete data support for maintenance decisions; connecting routine and periodic inspection data further lowers periodic inspection cost.
4. Applicable conditions and scenarios
- Large bridges across rivers/roads and complex-structure bridges
- Scenarios connecting routine inspection and periodic inspection data
- Expressway and municipal owners sensitive to safety and cost
5. Notes
Extreme weather and restricted areas require evaluation of operating conditions; special-structure bridges are recommended to combine fixed-point verification to ensure complete detection.
