New FA-PI Method Enhances Defect Detection in Concrete Structures

Researchers have developed a new method called Frequency-Amplitude Persistence Image (FA-PI) to improve the detection of defects in concrete structures using impact-echo testing. This technique constructs a two-dimensional image from the Fourier amplitude spectrum, representing frequency-bin location and amplitude. FA-PI was evaluated on experimental and public datasets, demonstrating superior performance over traditional raw and smoothed Fourier spectra, particularly in noisy conditions. The findings suggest that this 2D spectral representation enhances defect classification accuracy. AI

IMPACT This research could lead to more reliable and accurate non-destructive testing methods in civil engineering and infrastructure maintenance.

    From Fourier Amplitudes to Persistence Images for Impact-Echo Defect Detection

    arXiv:2610.18732v1 Announce Type: cross Abstract: Impact-echo testing is a nondestructive testing method used to detect internal defects in concrete structures. However, boundary reflections, structured interference, and measurement noise can produce complex Fourier amplitude spe…
