Abstract

The research focuses on the integration of artificial intelligence (AI) and cloud computing to develop a License Plate Recognition (LPR) model. The existing LPR model is a combination of the detection (YOLOv4-tiny) model and the recognition (ResNet-FC) model. The LPR model is then deployed from the local environment to the Intel® Developer Cloud for the Edge for further improvement (e.g. addition to the feature of selection of the inferencing engine provided by Intel). After deployment, this LPR model can be accessed from anywhere, anytime as long as internet connectivity is available. The purpose of the LPR model is to detect license plates in videos uploaded by users, reducing the need for manual monitoring and recording of car plate numbers. Next, further improvement was made by replacing the existing detection model (YOLOv4-tiny) with the more advanced version by using the YOLOv7 series. Subsequently, the detection model (YOLOv7-tiny) with the highest Mean Average Precision (mAP)@.5 of 0.936, and mAP@.5:.95 of 0.720, will replace the YOLOv4-tiny. Among the commonly used Intel hardware, the inference engine with Intel® Core™ i7-1185G7E and Intel® Iris® Xe Graphics 530 GPU integrated with the CPU had the highest performance. This inference engine had a processing time of 29 s and a frame per second (FPS) of 5.7 when applying to the LPR system with the YOLOv4-tiny detection model.
