Assessment of image processing methods for the determination of propagation of squat-type defects in rails
Abstrakt
We demonstrate the idea of squat-type defect measurement in the rail and the concept of tracking of the defect development using the techniques of image acquisition and image processing as well as the methods of metric spaces. We introduce the concepts of a set diameter δ(A) and the metric ρ1, which come from the properties of plane figures, to compare and to observe the development of the defects. We characterize the feasibility of the method to determine the dynamics of the defect development. The tests have shown that it is possible to apply the method with a camera during current diagnostic procedures provided that the distance to the rail is similar. Normalized metric enables easy comparison of the results and allows for the assessment of the reliability of the rails. The advantages of the method include simplicity and ability to observe the defects during the entire cycle of their development, which makes it possible to take the diagnostic decisions at the appropriate time
