In response to the challenges of high labor repetition, escalating labor costs, and low production efficiency in traditional hub classification and inspection processes, this paper proposes an automatic automobile hub classification system using the YOLOv8 network. The workflow of this system includes: first, collecting extensive X-ray images of automobile hubs to construct a comprehensive dataset encompassing various hub types; next, utilizing the YOLOv8 algorithm to train this dataset to generate a model capable of accurately distinguishing hub types. During the model training phase, improvements were made to the YOLOv8 algorithm based on the specific characteristics of hub classification, with Focal Loss introduced as the loss function, effectively mitigating the issue of imbalance between positive and negative samples and further enhancing the accuracy of hub classification. In the experimental validation stage, hub images were tested under different noise interference and lighting conditions. The experimental results demonstrate that the system can swiftly and accurately identify various types of hubs, with an average recognition accuracy of 98.43%, showcasing excellent classification accuracy and robustness.
