License plate recognition (LPR) is an advanced technology that uses computer vision and machine learning to automatically detect and read vehicle license plates. By analyzing images or video feeds from cameras, LPR systems extract alphanumeric characters from plates, enabling quick identification of vehicles.
How It Works
LPR involves several key steps:
- Detection – A camera captures an image of a vehicle, and the system locates the license plate.
- Preprocessing – The image is enhanced to improve clarity, adjusting for lighting, angles, or obstructions.
- Character Recognition – OCR (Optical Character Recognition) technology reads the plate’s characters.
- Verification – The system cross-checks results with databases for accuracy.
Applications
LPR is widely used in:
- Traffic Management – Monitoring speed, toll collection, and congestion control.
- Security – Tracking stolen vehicles or unauthorized access in parking lots.
- Smart Cities – Automating parking systems and law enforcement.
As AI improves, LPR is becoming faster and more reliable, transforming transportation and security.
