Vehicle Plate Recognition System Using Image Processing

Abstract

In this study, the license plate reading system, which is needed in security applications, automaticdoor systems, or parking lot entrance and exit processes, is designed. The main reasons for choosing this systemare that it greatly reduces the workload and contributes to the acceleration of operation in areas with heavytraffic. This work has been programmed with image processing methods on MATLAB and will take an imageinput with an internal or external camera system and give an output to the user. When we look at all thecountries of the world, it is observed that there are different shapes and sizes on the license plates. In this study,simple but effective morphological operations and Sobel edge detection method were used so that thesedifferences do not cause the system to make any mistakes. With this approach, the letters and numbers on theplate were divided by using the bounding box method, and an effective study was carried out. After this study,the template matching approach is used to identify the characters.
