N2 - The pantograph-catenary interaction is an important index of railway safety, which is always evaluated and analyzed by the position of the contact points. The tracking and locating of the contact points in online monitoring has always been an urgent problem due to the high speed of the train operation and various complex backgrounds. In this paper, we proposed an practical online tracking method for contact points. The position of the contact points can be obtained by the staggering of the edges of the pantograph and catenary, which are fitted by the points detected by template matching using line templates respectively. Next, the position in the image sequence can be further located in the area which was tracked by an kernel tracking method. The final precise contact points can be approximated to the corner by the gradient-based refinement method. The result running at a dataset collected in 200 fps when the train is running at the speed of 200 km/h shows that the proposed method can achieve effective and robust online contact points tracking.
