Rail Component Detection, Optimization, and Assessment for Automatic Rail Track Inspection

Abstract: In this paper, we present a real-time automatic vision-based rail inspection system, which performs inspections at 16 km/h with a frame rate of 20 fps. The system robustly detects important rail components such as ties, tie plates, and anchors, with high accuracy and efficiency. To achieve this goal, we first develop a set of image and video analytics and then propose a novel global optimization framework to combine evidence from multiple cameras, Global Positioning System, and distance measurement instrument … Show more

“…Therefore, automated and nondestructive inspection systems are strongly recommended for practical reasons [4]. For example, Fiber Bragg grating sensors [5,6], ultrasonic inspection [7], Eddy currents [8,9], MEMS gyroscope sensors [10], and visual inspection system (VIS) [11][12][13]. Ultrasonic inspection is very suited to internal crack detection, but the speed is very slow and it cannot detect surface defects in rail tracks.…”

“…When fasteners' positions and the switch are not at the same level line or fasteners themselves are damaged and missing, identification performance will also be affected. In addition, computer vision technology can also be applied to the identification of sleepers and fasteners, [4][5][6][7][8] but this technology is based on the images taken during tamping operation. If the shooting light is dim or sleeper itself is covered by ballast, the identification becomes also difficult.…”
