Design and Evaluation of YOLOv7-Based License-Plate Recognition for Mobile Vehicles Using Notebook-Raspberry-PI

Automatic License Plate Recognition (ALPR) has been a popular mechanism in daily traffic monitoring, and entrance control. Most of the ALPR devices are statically installed on the street posts or on the entrances. However, in Taiwan and some other countries, the public security greatly relies on the police mobile patrolling. The polices, on the motorbikes or on the cars, regularly patrol the streets and identify suspicious cars. This study aims at designing low-cost mobile ALPR systems using some affordable notebooks or Raspberry Pis. Based on the experiments, we suggest several models of hardware and various resolution images for satisfactory performance.
