Gantry Crane Container Number Recognition System

In modern ports and logistics parks, gantry cranes, as the core equipment for container handling, have their operational efficiency directly impacting overall operational performance. Container number recognition, as a critical link, has seen traditional reliance on manual verification become inadequate to meet the demands for high efficiency and accuracy. Leveraging advanced image processing technology, intelligent container number recognition systems have emerged as a key solution to enhance the automation level of gantry crane operations.
Core Technology: Integration of Image Processing and Deep Learning
1. High-Precision Image Capture
The system utilizes industrial-grade high-definition cameras with wide dynamic range (HDR) and low-light enhancement capabilities, enabling adaptation to complex environments such as strong light, backlight, rain, and fog. This ensures clear and stable container images, providing a high-quality data foundation for subsequent recognition.
2. Intelligent Image Preprocessing
Through techniques such as noise reduction, contrast enhancement, and edge sharpening, the system optimizes raw images to effectively eliminate environmental interference. Addressing common issues like surface contamination, rust, or partial occlusion on containers, the system automatically corrects image distortion, precisely locates the container number area, and enhances character recognizability.
3. Deep Learning Character Recognition
Based on convolutional neural networks (CNN) and optical character recognition (OCR) technology, the system rapidly segments and identifies container number characters. Trained on vast datasets of container numbers, the model achieves over 99% accuracy in recognizing printed, handwritten, and worn characters, significantly reducing the risk of misidentification.
4. Real-Time Processing and System Integration
Embedded high-performance processors ensure the system completes recognition within milliseconds and transmits results in real-time to backend management systems. Additionally, the system supports functions such as container number recording, automatic comparison, and anomaly alerts, meeting the high-efficiency demands of continuous operations.
Technical Advantages and Industry Value
- High Adaptability: Algorithms are optimized for different container types (e.g., 20GP, 40HQ) and ISO standards, compatible with global mainstream container number formats, and suitable for diverse application scenarios.
- Stability and Reliability: Supports local processing and cloud data collaboration, ensuring stable system operation even under poor network conditions.
- Scalability: The system can be further integrated with functions such as weight detection and container damage identification, providing more comprehensive intelligent solutions for ports and logistics parks.
By deeply integrating image processing and artificial intelligence technologies, the gantry crane container number recognition system achieves a leap from "manual verification" to "intelligent recognition," significantly enhancing operational efficiency and accuracy.
