Client:

Organisations and establishments requiring enhanced convenience and security at entry points.

Challenge:

To develop and implement an automatic gate control system that provides seamless access control and recognizes licence plates for efficient entry management.

Solution:

1. Gate Control System:

• Development of an automatic gate control system for entry places requiring protection and security.
• The system operates automatically, minimising manual efforts.
• Integration of artificial intelligence and modern PCs with high-quality CCTV cameras.
• Video frames containing visible car licence plates are captured and processed.

2. Training the ML Model:

• Acquisition of Images:
  • High-resolution cameras with infrared capabilities are used to capture vehicle photos round the clock.
  • Front images of vehicles are collected, ensuring minimal reflections and optimal camera angles.
  • Cameras are triggered to capture photos of passing vehicles using radar or motion detection.
• Image Annotations:
  • 10,000 sample images are collected for training.
  • Annotations for these images are created using labelling applications, preferably in XML format.
  • Annotations provide detailed information about objects, including height, width, angle, path, and label name.
• Training:
  • Multiple neural networks are employed to train the annotated images alongside their respective XML files.
  • The trained model detects number plates from recorded video frames.

3. Predictions:

• Image Enhancement and Pre-processing:
  • Captured car images are processed using Python libraries to enhance their quality.
  • Pre-trained models are applied to the frames to detect licence plates.
  • Skewness of objects is checked to improve the accuracy of number plate recognition.
• Database and Results:
  • Recorded videos are saved, including the captured number plate information, in a database.
  • Results are stored in CSV format, including incoming and outgoing cars’ image frames.

Results:

• The automatic gate control system significantly enhances convenience and security at entry points.
• The system achieves a recognition rate of approximately 90% for vehicles, indicating high efficiency.
• Efficient licence plate recognition enables effective entry management and access control.

Benefits:

• Improved convenience and security for organisations and establishments.
• Streamlined access control with minimal manual efforts.
• Enhanced accuracy and efficiency in licence plate recognition.
• Detailed records of incoming and outgoing vehicles for better monitoring and analysis.
