| Summary: | Automated License Plate Detection and Recognition (ALPR) is a technology that identifies and reads license plates in transportation and surveillance systems. However, ALPR is a challenging task due to several factors, including differences in vehicle license plates between countries, a lack of public datasets, environmental factors that can decrease the performance of recognition models, and challenging lighting conditions for vehicle license plates. In this work, we present an ALPR system for real-time applications specifically designed to detect and recognize Moroccan license plates. Our contribution is threefold. First, we employ the YOLOv3 algorithm to extract valuable features from input scenes and detect vehicles. Second, we track vehicles and assign a unique id to each detected vehicle. Finally, we detect and recognize the plates of tracked vehicles based on computer vision techniques and a voting system. The latter is a post-processing step that selects the most consistent content as the final prediction. Furthermore, we collected and annotated a set of videos that contain vehicles with Moroccan license plates in various conditions. The collected data is used to assess the performance of our system. The obtained results demonstrate that our system achieves an accuracy of 99.19% and 95.62% for detection and recognition, respectively. |
