Container Damage Detection System | AI-Powered Fully Automated Container Damage Recognition Solution for Port Yards

To address industry pain points such as low efficiency in manual container inspections at ports and yards, frequent missed or false detections, and imprecise damage localization, Fuwei Intelligent has developed a proprietary container damage detection system. Leveraging multi-angle high-definition imaging and deep learning AI algorithms, the system achieves fully automated, non-contact detection of damage across the entire container surface. It provides high-precision quantitative assessment using a 3cm × 3cm grid and is designed to support high-speed throughput operations at terminals.

I. Multi-camera panoramic imaging for comprehensive coverage

The imaging hardware is arranged in zones to fully cover five sides of the container:

1. Left, right, and top sides: Three line-scan cameras capture seamless panoramic images without distortion or stitching artifacts.

2. Front and rear ends (door areas): Two global-shutter area-scan cameras mitigate interference from water stains, reflections, and motion blur.

The equipment features high IP67/IP66 protection ratings, ensuring reliable all-weather outdoor operation despite port conditions such as salt spray, light rain, and strong backlighting.

II. Deep learning AI algorithms for precise identification of seven damage categories

The system employs a dual-layer neural network combining detection and pixel segmentation, integrated with the CBAM attention mechanism. It is specifically optimized to detect seven types of container damage: rust, dents, scratches, holes, and weld cracks.

- Standard detection unit: 3cm × 3cm; damage localization error: ≤ ±5cm;

- Overall recognition rate: ≥ 90%; missed and false detection rates: < 5%;

- Stable image capture at vehicle speeds of 0–15 km/h (constant speed or with minor acceleration/deceleration).

III. Core operational performance meeting high terminal throughput demands

1. Efficiency: Total time from capture to result generation is ≤ 10 seconds per container; hourly throughput capacity is ≥ 300 containers;

2. Stability: Supports 24/7 continuous operation with an MTBF (Mean Time Between Failures) of ≥ 10,000 hours;

3. Environmental compatibility: Operates in lighting conditions ranging from 100 lux to 100,000 lux, as well as in light rain and foggy weather;

4. Output: Automatically maps damage using a grid overlay and color-codes it into three severity levels: minor, moderate, and severe.

IV. Lightweight software functionality balancing automated inspection with manual operations

1. Panoramic grid visualization: Overlays a standard grid onto the panoramic container view, allowing for localized zoom-ins to verify damage details;

2. Manual editing and traceability: Supports manual addition, deletion, and modification of damage annotations, with full operation logs retained for traceability;

3. Comprehensive data management: Locally stores container images and inspection reports for 180 days, with automated cleanup alerts upon expiration;

4. Convenient integration and export: Standard HTTP interfaces connect to container management and TMS systems; supports one-click export of JPEG images and Excel statistical reports;

5. Historical comparison and retrieval: Enables rapid searches by container ID, time, or damage type to compare changes in container condition over time.

V. Standardized acceptance for worry-free deployment

The Fuwei container damage inspection system comes with comprehensive acceptance criteria: 72 hours of continuous, full-load operation without system failure; stable performance across various weather conditions and operating speeds; and mandatory compliance with all metrics regarding recognition accuracy, efficiency, and software functionality prior to delivery. Standardized reference images of damage types are provided to assist with on-site maintenance and manual verification.

Compatible with 20ft, 40ft, and 45ft dry containers, reefers, and flat-rack containers (suitable for both steel and aluminum bodies), this system offers a one-stop solution to the challenges faced by port yards—namely the high costs, low efficiency, and inconsistent standards associated with manual container damage inspection.
