基于改进YOLOv8n的船舶设备拆装流程规范性评估方法
Operation standardization evaluation method based on improved YOLOv8n for ship equipment disassembly and assembly
摘要
Abstract
[Objectives]The standardization of ship engine room operations is a critical component of ship safety management.Therefore,the practical examination for crew members includes the disassembly and as-sembly of ship equipment as a key assessment item.To enhance the digitalization and intelligence of crew practical examinations,a computer vision-based automated recognition method for assessing the standardiza-tion of ship equipment disassembly and assembly processes is proposed.[Methods]First,the backbone net-work of the ship equipment detection model is constructed using YOLOv8n,and the shuffle-attention(SA)mechanism is introduced to improve the model's feature extraction capability and training efficiency.Sub-sequently,a reparameterized generalized feature pyramid network(GFPN)fusion structure is incorporated in-to the neck network to enhance the model's ability to fuse multi-scale features.Finally,the original CIoU loss function is replaced with the wise intersection over union(WIoU)loss function to improve the model's accur-acy.[Results]Experimental results on a self-constructed dataset demonstrate that,compared to YOLOv8n,the improved object detection algorithm achieves a 0.15 increase in mean average precision and a 0.6 frames-per-second improvement in real-time detection,enabling accurate recognition of the disassembly and as-sembly processes of gear pumps.[Conclusion]The improved algorithm exhibits superior recognition cap-abilities and is better suited for identifying the standardization of ship equipment disassembly and assembly processes.关键词
