This invention relates to the field of gear surface defect detection technology, and more particularly to a cross-domain gear surface defect detection method and system. To enrich the diversity of training samples and reduce background interference, an implicit information fusion strategy based on Fourier decoupling is proposed. By retaining invariant phase information and weakening amplitude information, the model can learn more robust semantic features. Addressing the difficulty in bridging inter-domain distribution differences, a domain adversarial adaptation framework is constructed to reduce global domain offset, and a domain-aware attention mechanism is designed to guide the model to focus on semantic regions with cross-domain adaptive value. Based on global alignment, the maximum mean difference of class prototype labels is designed, further achieving more refined class-level conditional alignment on top of global adversarial alignment. This invention effectively improves the detection accuracy of surface defect detection models for gear surface defects in unsupervised cross-domain scenarios.
