  • Rail inspection is very important for ensuring safety and preventing dangerous situations. Track superstructure can have different types of anomalies such as defects of rail surface and sleepers, missing of fastening elements and deviations in the contour of the ballast. In this paper we present a vision-based technique for automatically detecting the absence of the fastening bolts that secure the rails to the sleepers. The inpection system uses images from a digital line scan camera installed under a train. The images are pre-processed by using several combinations of WT and PCA methods. Two different types of classifiers analyse the images in order to evaluate the pre-processing technique that gives the highest rate in detecting the presence of the bolts. The final detecting system (the best combination pre-processing technique and classifier) has been applied on a long sequence of real images showing a high reliability and robustness. (literal)
