Desenvolupament del sistema de control d’accés al nucli antic de Sant Llorenç de Morunys

Abstract

This project includes the installation of a vehicle access control system in the old town of Sant Llorenç de Morunys : - Portal de la Capella - Portal del Puit. The purpose of the project is to minimize the social and landscape impact caused by this motorized traffic . The installation is formed by a system of IP cameras to capture and transmit the different accesses, which will be analyzed and stored by a registration plate reading system and resulting data management. The reading system is based on a computer vision system known as ALPR or ANPR (Automatic Number/License Plate Recognition). This is a method that uses OCR (Optical Character Recognition) in image recognition to read license plates and extract their alphanumeric values and detect its existence and position. On the other hand, a database and web interface are created for the management and interaction of the information generated. The features offered are the following: add authorized vehicles, add periods of days when access is restricted, handle license plate reading errors, generate PDF to the sanction process and lastly show access statistics. Finally, readings have been validated in different tests conducted throughout the project and an usability analysis has also been made to adapt the design to the client’s needs.
