Overview

Model evaluation demonstrates enhanced defect detection accuracy in industrial gear datasets, highlighting the benefit of robust hybrid attention.

Key Points

To develop a high-efficiency deep learning model capable of detecting gear surface defects under challenging conditions, including multiscale, low-contrast, and complex-textured features.
Built the YOLO-RCHA model upon the YOLOv5-v7.0 architecture by integrating a C3 with Global Grouped Coordinate Attention Pyramid (C3GGCAP) module for enhanced local feature extraction.
Incorporated a C3 Median-Enhanced Channel Spatial Attention (C3MECSA) module into the neck to suppress noise and added a Global Channel Shuffle Spatial Attention (GCSSA) module before the head for cross-dimensional interaction.
Evaluated performance on the NEU-GSD and NEU-DET defect benchmark datasets using mean average precision (mAP@0.5).
Achieved an mAP@0.5 of 97.0% on the NEU-GSD dataset, reflecting a 0.8% increase over baseline YOLOv5-v7.0.
Attained an mAP@0.5 of 75.7% on the NEU-DET dataset, representing a 1.6% increase compared to baseline YOLOv5-v7.0.
