Visual Inspection of Railroad Tracks
In this dissertation, we have developed computer vision methods for measurement of rail gauge, and reliable identification and localization of structural defects in railroad tracks. The rail gauge is the distance between the innermost sides of the two parallel steel rails. We have developed two methods for evaluation of rail gauge. These methods were designed for different hardware setups: the ...
متن کاملAutomatic Persistent Inspection of SkyTran Track System
The monitoring of the SkyTran track condition is imperative. Damaged tracks can cause a fatal crash that can even claim lives. A mechanism for an automatic persistent inspection of SkyTran track system is suggested. The paper suggests employing basic digital camera that can produce JPEG images for this task. If a damage track segment is detected, the traffic in this segment should be halted imm...
متن کاملRailway track inspection using GPR
Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...
متن کاملLaser-air Hybrid Ultrasonic Technique for Dynamic Railroad Inspection Applications
Laser-Air Hybrid Ultrasonic Technique (LAHUT) combines laser generation with air-coupled detection of ultrasound. The technique is non-contact and has the characteristic of operating from remote distances. Acoustic wave laser-generation apparatus can be meters away from the interrogated surface while air-coupled detection standoff can be on the order of several centimeters. The technique has th...
متن کاملDynamic railroad inspection using the laser-air hybrid ultrasonic technique
In recent years, remote non-contact NDE techniques have been sought in an effort to improve railroad related inspection operations. More specifically, efforts have been aimed at increasing the inspection coverage and performing dynamic inspections for railroad tracks and wheels. Throughout most of the 20th century, dynamic inspections of railroad tracks have been developed and performed, howeve...
