Automatic Number Plate Recognition System

This project presents an Automatic Number Plate Recognition (ANPR) System for automated vehicle access control and monitoring. The system uses the ESP32-CAM module to capture vehicle images and applies OpenCV and EasyOCR techniques to extract vehicle registration numbers. The extracted number is verified against a MySQL database of authorized vehicles.Based on the verification result, the system displays the access status on an OLED display and controls gate operation using a servo motor. The proposed solution reduces manual intervention, improves security, and provides an efficient and low-cost vehicle authentication mechanism suitable for residential societies, parking areas, educational institutions, and industrial premises.
