ĐỀ TÀI LUẬN VĂN : Nghiên cứu ứng dụng mô hình YOLOv5 nhận diện đa vật thể trong ảnh cho hệ thống giám sát tốc độ xe bằng camera theo thời gian thực. TASKS AND CONTENTS: - Develop a traffic sign recognition system, specifically for speed limit signs, from images captured by cameras on the road. - Employ the Jetson Nano embedded computer as the central processing unit to run the YOLOv5 model for detecting speed limit signs. Simultaneously, compare the sign recognition results with the vehicle's current speed accessed from the OBD-II system.
Subsequently, the system provides a direct alert to the driver on the screen if the speed limit is exceeded. TASKS STARTING DATE: February 06th, 2023. TASKS ENDING DATE: June 12th 2023. INSTRUCTOR: Trần Đăng Long, Ph.

Ho Chi Minh City, 15th July, 2023 Researcher, Nguyen Ngoc Truc iii ABSTRACT This study aims to two objectives. Firstly, the design of a real-time traffic sign detection system for automobiles, with a specific focus on speed limit signs, using the YOLOv5 model.
Secondly, the study includes an assessment of the practical implementation of the traffic sign detection system by integrating it with a speed warning system that can be integrated into vehicles. This study includes several key tasks. Firstly, extensive research was conducted to identify real-time detection methods suitable for traffic signs. Subsequently, a comprehensive dataset of speed limit traffic signs was prepared, consists of 3200 images.
