System for Automatic Toll Collection Using Image Processing and Raspberry PI
摘要
The application will continuously monitor the IR Sensor. Upon detecting a vehicle approaching the gate, it will capture a snapshot of the vehicle's number plate. Subsequently, through the utilization of OpenCV and cloud technology, we will extract the number plate information. This information will be cross-referenced with an existing database, which contains known vehicle numbers along with associated balances recorded in a file format. The system will compare the captured number plate data with the database. If the vehicle's number is found, and the associated balance is sufficient, the system will deduct the appropriate amount and control the servo motor to open or close the gate. However, if the balance is insufficient or if the number plate data is not present in the database, the system will trigger a buzzer alarm and display a message on the LCD screen, prompting the vehicle owner to make a manual payment. Additionally, a push button will be provided to enable manual operation of the servo motor. The implementation of this system will significantly reduce the need for human intervention in managing gate access and payments.
