English(EN) From Fourier Amplitudes to Persistence Images for Impact-Echo Defect Detection

新的FA-PI方法增强了混凝土结构中的缺陷检测

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-14 04:00

研究人员开发了一种名为频率-幅度持久性图像（FA-PI）的新方法，以改进使用冲击回波测试检测混凝土结构中的缺陷。该技术从傅里叶幅度谱构建二维图像，表示频率箱位置和幅度。FA-PI在实验和公共数据集上进行了评估，与传统的原始和平滑傅里叶谱相比，尤其是在嘈杂条件下，表现出优越的性能。研究结果表明，这种二维频谱表示提高了缺陷分类的准确性。 AI

影响这项研究可能为土木工程和基础设施维护带来更可靠、更准确的无损检测方法。
