Survey on vision-based railway track defect detection
智能科学与技术学报The detection of train track defects is of great significance to the safety of rail transportation, but current manual inspection can no longer meet the complex and heavy track inspection requirements.

Rail defect detection using ultrasonic surface waves
Current testing of the rail network is limited in terms of both speed of testing and PF accuracy of detecting surface defects such as gauge corner cracking.

Time of flight diffraction and imaging (TOFDI) [PDF]
Time of flight diffraction and imaging (TOFDI) is based on time of flight diffraction (TOFD), adding cross-sectional imaging of the sample bulk by exploiting the scattering of ultrasonic waves from bulk defects in metals.

Evaluation of rail surface cracks using laser ultrasonic technique
, 2017 In order to detect and evaluate rail surface fatigue cracks, this paper proposes a non-contact laser ultrasonic technique based on data fusion and wavelet packet analysis. The theory for defect depth detection using Rayleigh wave was described via finite
