Lightweight Visual Localization of Steel Surface Defects for Autonomous Inspection Robots Based on Improved YOLOv10n
Unlocking Precision: AI for Autonomous Steel Defect Detection
This research introduces KDM-YOLO, an enhanced lightweight deep learning model built upon YOLOv10n, specifically designed for autonomous inspection robots to detect steel surface defects. Addressing challenges like fine-grained textures, scale variations, and complex backgrounds, KDM-YOLO integrates KernelWarehouse Convolution (KWConv) for improved edge feature extraction, a C2f-DRB module for enlarged receptive fields and long-range dependency, and a Multi-Scale Attention Fusion (MSAF) module for adaptive feature integration. The model achieves superior accuracy (mAP@50 of 95.4%) and recall (93.9%) while maintaining high inference speed (155.6 f/s) and a compact parameter count (3.29 M), making it ideal for real-time deployment on embedded platforms.
