Abstract

Nondestructive testing of rails is regularly conducted using various approaches and methods, including eddy current testing, to ensure railroad safety. Automatic analysis of large data arrays (defectograms) from the corresponding equipment is an important problem. The analysis is the process of detecting defective places and identifying structural elements of a railroad track by using defectograms. This paper is devoted to pattern recognition of structural elements of railroad rails in defectograms of multichannel eddy current flaw detector. We investigate two classes of structural elements: (1) axle counters and (2) rail crossings. Patterns (long marks) that cannot be assigned to these two classes are conventionally considered as defects and are attributed to a separate (third) class. Pattern recognition in defectograms is carried out using a convolutional neural network based on the TensorFlow open library. For this purpose, each defectogram area selected for analysis is converted into a grayscale image with a size of 30 by 140 pixels.
