Client: Xiamen Road and Bridge Construction Group Co., Ltd

Location：Huli District, Xiamen City, Fujian Province

Inspection Scope: Five sea-crossing bridges

Work Period: May 2025 – December 2025

Service to Scope: Equipment Deployment, System Development, Route Planning, Disease Identification

The project addresses Xiamen's cross-sea bridge maintenance challenges through automated inspection systems integrating drone hangars, 5G-A connectivity, and AI-powered corrosion mapping. Technical frameworks overcome GPS-denied navigation in structural voids and EMI interference, achieving millimeter-level defect detection accuracy.

Implementation resolved four core technical barriers: signal dropout across long spans, position drift under electromagnetic interference, equipment degradation from salt mist exposure, and optical recognition errors in dynamic lighting.

Visual SLAM navigation fused with LiDAR point clouds enables blind zone inspections, while edge computing processors host multi-tier AI validation models. The closed-loop "detection-assessment-action" workflow establishes industry benchmarking protocols, demonstrating quantifiable efficiency gains in structural health monitoring.
