本研究旨在构建面向NDE 4.0的自动化缺陷检测与分类框架,针对现有信息不足、虚拟缺陷增广利用不充分及框架可行性验证等问题展开。以223张飞机焊缝CR图像为基础数据源,采用虚拟缺陷增广与标准增广技术进行数据扩充。基于优化后的数据集训练改进的U-net模型,生成缺陷语义分割图。通过案例(Case)、精确度与误报率等NDE指标评估模型性能。结果表明,在90/95尺寸误差条件下,关键特征表现出强区分能力,检测灵敏度优异。综合增广策略在焊缝区域表现最优,且因快速推导能力,能高效处理大尺寸图像。现场专业人员评估认为,该系统可作为检测流程中的可靠辅助工具,不受特定设备或程序差异影响。
原文摘要 · Abstract (English)
This investigation attempts to create an automated framework for fault detection and organization for usage in contemporary radiography, as per NDE 4.0. The review's goals are to address the lack of information that is sufficiently explained, learn how to make the most of virtual defect increase, and determine whether the framework is viable by using NDE measurements. As its basic information source, the technique consists of compiling and categorizing 223 CR photographs of airplane welds. Information expansion systems, such as virtual defect increase and standard increase, are used to work on the preparation dataset. A modified U-net model is prepared using the improved data to produce semantic fault division veils. To assess the effectiveness of the model, NDE boundaries such as Case, estimating exactness, and misleading call rate are used. Tiny a90/95 characteristics, which provide strong differentiating evidence of flaws, reveal that the suggested approach achieves exceptional awareness in defect detection. Considering a 90/95, size error, and fake call rate in the weld area, the consolidated expansion approach clearly wins. Due to the framework's fast derivation speed, large images can be broken down efficiently and quickly. Professional controllers evaluate the transmitted system in the field and believe that it has a guarantee as a support device in the testing cycle, irrespective of particular equipment cut-off points and programming resemblance.
