GSP-YOLO: An Efficient Tire Detection Algorithm for Truck Scale Scenarios

Résumé fourni par la source

Truck scale systems are often located in complex industrial environments, and existing inspection methods based on the appearance of an entire vehicle are difficult to accurately locate trucks in space-constrained scenarios. This study proposes GSP-YOLO, a tire detection algorithm for truck scale scenarios based on an improved YOLOv8n, that assists in locating trucks on the scale by detecting tires and enhances the detection performance in industrial environments. GSP-YOLO incorporates a global-to-local spatial aggregation module into the neck structure to improve the perception of tires on small scales. A shared detail-enhanced convolutional detection head is designed in the detection head to enhance its ability to recognize complex features while reducing the computational cost. The model also replaces conventional convolution with poly-scale convolution to enhance object recognition capability and reduce feature loss. Additionally, the wise-intersection over union loss function is employed as the bounding box regression loss to suppress competition among high-quality anchors and reduce the impact of low-quality samples, thereby improving detection performance. The experimental results demonstrated that GSP-YOLO achieves an mAP50 of 89.3% on the dataset, representing a 2.0% improvement over the baseline model, and an increase of 0.9% in mAP50–95. This model significantly enhances the detection capability within truck scale systems and ensures reliable performance in complex industrial environments.
