    • 摘要: 在机载设备履历本生成过程中,履历本数据填写及二维码粘贴由人工完成,自动化程度低。针对此问题,以某型机载设备履历本生成场景为研究背景,提出了一种基于YOLOv8-DM的履历本自动生成方法。一方面,实施采集典型样本拍摄图像作为数据集,采用YOLOv8-DM模型进行数据训练,实现对机载设备履历本二维码的检测并提取二维码数据;另一方面,基于提取的履历本二维码数据及履历本指标数据构成的履历本数据库自动化生成履历本电子文件;最后,基于YOLOv8-DM对纸质履历本二维码进行缺陷剔除以提高履历本制作质量。结果表明:模型对履历本二维码检测平均精度均值()达98.9%;模型对履历本二维码缺陷检测平均精度均值()达98.6%,较其它模型提高0.6至8个百分点;履历本生成速度达300本/h,较人工制作速度提升14倍;履历本制作较人工制作缺陷率降低98.7%;履历本制作成本下降约5000元/套(按40本/套计算)。因此,所提方法适用于机载设备履历本自动生成,提升了制作速度及制作质量的同时具有较高的经济效益,并可在其它需要制作履历本的领域扩展。

       

      Abstract: In the generation process of airborne equipment logbooks, data entry and QR code pasting are currently performed manually, resulting in a low level of automation. To address this issue, this study proposes an automatic logbook generation method based on YOLOv8-DM, utilizing a specific scenario for producing logbooks of airborne equipment as the research background. Firstly, representative sample images are collected to construct a dataset, and the YOLOv8-DM model is used for training to detect logbook QR codes and extract their embedded data. Secondly, an electronic logbook file is automatically generated based on the extracted QR code information and logbook index data, forming a complete logbook database. Finally, YOLOv8-DM is further employed to identify and remove defective QR codes on printed logbook pages, thereby improving the overall production quality. Experimental results show that the proposed model achieves a mean Average Precision (mAP₅₀) of 98.9% for QR code detection and 98.6% for QR code defect detection, exceeding other models by 0.6–8 percentage points. The logbook generation speed reaches 300 books per hour, representing a 14-fold increase compared to manual production. The defect rate is reduced by 98.7%, and the overall production cost decreases by approximately 5, 000 CNY per set (40 books per set). Therefore, the proposed method is well-suited for automatic generation of airborne equipment logbooks, offering significant improvements in both production speed and quality, along with substantial economic benefits. It can also be applied to other fields that require logbook generation.
