1. How is 0.05mm achieved?
Imaging capability depends on pixels and focal length: the 100MP medium-format camera with a telephoto lens clearly reproduces 0.05mm or even smaller detail at close range. This capability was verified by field caliper measurement by a water-conservancy customer (captured at 3 meters).
2. Why is the engineering standard 0.1mm?
The higher the resolution, the smaller the single-frame coverage and the more drastically operational efficiency drops — doubling resolution reduces efficiency by about four times. Engineering practice therefore uses 0.1mm as the routine recognition standard, and shortens the distance for targeted re-capture when higher accuracy is needed, balancing accuracy and efficiency.
3. Accuracy vs efficiency trade-off
| Accuracy standard | Applicable scenario |
|---|---|
| 0.1mm (routine) | Full-bridge automated inspection |
| 0.05mm (high precision) | Close-range targeted verification |
4. Applicable conditions and scenarios
- Areas with high-precision recognition needs for fine cracks
- Verification scenarios requiring close-range targeted re-capture
- Routine inspection follows the 0.1mm standard to ensure operational efficiency
5. Notes
Higher accuracy comes with reduced operational efficiency and distance constraints; choose the standard per detection needs. Results are recommended for review by professional engineers.
