The purpose of this thesis was to research and develop an ALPR (Automatic License Plate Recognition) system to be used as part of a bigger family of sys-tems, in order to enable users to opt-in into the system’s functionality. This was done in a multitude of steps, ranging from researching and developing a cus-tom algorithm, to trying out commercial algorithmic solutions, and finally to de-veloping the actual software to integrate as a solution.
The methodologies used for this thesis were mainly quantitative, as research-ing and testing different solutions required development of a test suite to measure the accuracy of different iterations of the ALPR.
The result of this thesis was a working ALPR solution in the form of a Java ap-plication using Spring Framework. It was discovered along the way that open-source frameworks that could be used as a basis (and the one that was used) had limitations that would only ever allow the ALPR to reach an accuracy level that, while not bad, was inadequate for the applications the ALPR system was going to be used for.
