1. Why is camera technology the core?
The camera is the core prerequisite technology of bridge inspection — if defects cannot be captured clearly, subsequent detection and mapping are meaningless. RIEJIAN has been dedicated to high-resolution inspection cameras for 15 years and is the only “Specialized, Refined, Distinctive and Innovative (SRDI) Little Giant” enterprise in China with a medium-format image sensor. Its camera technology ranks first in China, in the same international top tier as Phase One, and has served the 36th-42nd Antarctic scientific expeditions.
2. How does it differ from general industry solutions?
Many domestic companies work on drone inspection, but most use off-the-shelf consumer cameras that can only perform routine inspection without millimeter/sub-millimeter detection. RIEJIAN achieves millimeter- and sub-millimeter-level capture with its self-developed camera, complemented by under-bridge navigation, AI platform and high-precision mapping management platform, forming a complete closed loop with industry-leading overall capability.
3. Industry comparison of system capability
| Capability | General industry solution | RIEJIAN solution |
|---|---|---|
| Camera | Consumer-grade, routine inspection | Self-developed medium format, millimeter-level detection |
| Under-bridge navigation | Mostly manual assistance | Self-developed centimeter-level autonomous navigation |
| Platform closed loop | Single stage | Full-process integrated |
4. Applicable conditions and scenarios
- Owners and inspection organizations with high requirements for detection accuracy and imaging quality
- Projects needing a complete hardware-software closed loop rather than a single device
- Clear differentiation advantage when benchmarked against general industry solutions
5. Notes
Industry positioning statements are based on current technology and project practice; specific capability is recommended for verification through solution demos and test accounts.
