Anomaly detection using a modified kernel-based tracking in the pantograph–catenary system

作者：

Highlights：

• A new contactless condition monitoring method is proposed for anomaly detection in the pantograph–catenary system.

• Kernel-based tracking is modified for a robust tracking of catenary wire.

• The foreground detection and object tracking are combined for simultaneously arcing detection.

• The detailed analysis of the trajectory of the contact wire gives useful information to evaluate the pantograph condition.
