A comparison study of rail fault detection methods in the literature

Abstract

Railsareone of themostimportantcomponents of railwaytransportation. It is neededthattherails can be observed at regularinterval in ordertoensurethesafety of railwaytransportation, preventthedisruption of transportation, andavoidaccidents. To be inspected of railsurfacebyusingmanualtechniques, bothdamagestherailsurfaceandleadstodisruption of railway transport. Railprofileanalysismethodsthatutilizecontactlessimageprocessi ngtechniquesareavailable in theliterature in ordertoavoidtheseproblems. Thispaperpresents a comparison of raildefectdetectionmethodsthatareavailable in theliterature. Thesemethods in theliteraturehavebeencompared in terms of feasibility, performance, accuracy, elapsed time, andimageprocessingtechniquesused. Theadvantagesanddisadvantages of thesemethodsrelativetoeachotherareexamined in thisarticle
