Automatic Container Nameplate Weight Recognition Technology

In container logistics management, the accurate identification of nameplate weight is crucial for cargo transportation safety, customs supervision, and terminal operational efficiency. Fuwei Intelligence integrates container nameplate weight recognition into the high-definition container number recognition system using advanced OCR (Optical Character Recognition) technology and AI image analysis capabilities, achieving fully automated and high-precision data collection.
I. Technical Principles of Nameplate Weight Recognition
Container nameplates are typically fixed in prominent positions on the container, displaying key information such as the container number, maximum gross weight (MAX GROSS), and tare weight (TARE). Fuwei Intelligence achieves automatic nameplate weight recognition through the following steps:
1. High-definition image capture:
The system uses deployed multi-angle high-definition cameras to trigger snapshots when vehicles pass through gates or checkpoints, ensuring clear imaging of the nameplate area. Even with dirt, glare, or tilting, image enhancement algorithms optimize the results.
2. Target localization and segmentation:
Based on deep learning models, the system accurately locates the nameplate area and segments weight information (e.g., "MAX GROSS: 30,480 KG"), eliminating background interference.
3. OCR intelligent recognition:
Utilizing a multilingual OCR engine, the system supports the parsing of nameplate text in various formats, automatically extracts numbers and units (e.g., KG, LB), and ensures data rationality (e.g., weight value ranges) through logical validation.
II. Technical Advantages and Industry Value
1. High efficiency and accuracy:
The entire recognition process requires no manual intervention, with single-container processing time <3 seconds and an accuracy rate exceeding 98%, far surpassing traditional manual recording.
2. Multi-system collaboration:
Weight data can be integrated with weighing systems and customs platforms for real-time verification of whether the actual load exceeds limits, avoiding transportation risks or compliance issues.
3. Expanded application scenarios:
Combined with subsystems such as RFID and electronic seals, it forms a comprehensive smart customs clearance solution, assisting customs and terminals in achieving end-to-end cargo traceability.
III. Fuwei Intelligence’s Differentiated Capabilities
- Adaptation to complex environments: Algorithms optimized for scenarios such as rain, snow, dirt, and low light ensure stability.
- Global standard compatibility: Supports international standard nameplate formats like ISO6346, adaptable to containers from different regions.
- Seamless system integration: Through open APIs, it interfaces with TOS (Terminal Operating System) and logistics platforms, enhancing data flow efficiency.
Through technological innovation, Fuwei Intelligence has upgraded nameplate weight recognition from "manual transcription" to "AI automated collection," driving the port and logistics industry toward digitalization and intelligence. In the future, we will continue to optimize our technology to provide global customers with more efficient container management solutions.
