The geometry status of electric railway catenary is critical to the stability of railway power
supplying. An accurate and efficient vision measurement approach for railway catenary …

Vision-based abnormal object detection in railway track inspection images is one of the
critical tasks to ensure the safety of railway transportation. Even though many machine …

In order to increase the operation safety of the railway vehicles, including subways,
tramways, and all other types of the trains running on the railroads, it is necessary to inspect …

In order to decrease the noise and vibration of operation in railway tracks, it is necessary to
inspect the status of them frequently. A main task in inspection of railway tracks is …

Dynamically measuring rail profile using the structured-light vision suffers from random
vibrations on the line laser projector, which would cause distorted rail profiles. This paper …

Rail profile measurement is one of the most critical tasks for track quality inspection to
ensure the safe operation of track systems. In modern railway systems, laser triangulation …

For rail wear measurement, the process of profile registration is critical. Nowadays, the
widely used method is the rail waist double circle segment method (DCS). However, this …

Measuring rail profile in the presence of multiple degrees of freedom vibration is a very
challenging task. This paper presents a novel method based on the local affine invariant …

Rail wear inspection is vitally important in the railway industry. Conventional methods mainly
use manual or static measurements to detect rail wear, which are inefficient, imprecise, and …

The diagnosis of railway system faults is significant for its comfort, efficiency, and safety. The
rail surface wear is the key impact factor when considering the health conditions of rails. This …
