AI Technical Summary
Existing vehicle target recognition methods have low recognition accuracy in complex scenes, especially under factors such as occlusion, changes in lighting, and background interference, which makes it difficult to effectively capture subtle features, resulting in a decrease in detection accuracy.
The YOLO-FSG model is adopted, and the C3K2 module in the backbone network is replaced with a spatial frequency hybrid convolutional module (SFHC), a P2 detection head is added, and a global local adaptive module (GLAM) is introduced to improve vehicle recognition accuracy.
It significantly improves the accuracy and noise resistance of vehicle target recognition, and can achieve accurate detection in complex lighting and multi-scale scenes. The evaluation indicators are improved by 3%-5%, surpassing other mainstream models.
