The automated parking fee calculation using license plate recognition system

Designing of an automated parking fee calculation using license plate recognition aims to solve the problem of identifying the vehicle license plate number at the parking lot. The image processing theories and researches related to character recognition were used to design the system. The techniques used in this system are RGB Image to Grayscale Image, Grayscale Image to Binary Image, Edge Detection, Noise Reduction, Character Segmentation and Character and Number Recognition. The system starts from capturing the image of license plate, processing the image with different techniques and registering date and time of the license plate image both inbound and outbound in the database to calculate the parking fee. The result of the experiment shows that the system is able to recognize the characters in 41 of 50 license plate images or 93.42% accuracy. The accuracy of calculating the parking fee by using the prescribed fee equals to 100%. The efficiency of license plate recognition of this system can be 100% if the license plate images are clear, sharp, no reflection and the background should be white or light color and no pattern.
