Abstract: PURPOSE: A method for measuring the dynamic displacement of an electric vehicle lane is provided to detect a change of a contact point according to an interaction of a pantograph and the electric vehicle land and to measure the dynamic height and dynamic declination of the electric vehicle lane regardless of a place or a vehicle model. CONSTITUTION: A method for measuring the dynamic displacement of an electric vehicle lane(140) comprises: a step of outputting image signals, which are photographed the electric vehicle lane and a pantograph(130), by being arranged on the top of a railway vehicle(110) which is operated by using the electric vehicle lane; a step of detecting a position of the pantograph by receiving the image signals and converting the same into digital image signals; a step of detecting an inclined surface of the pantograph; a step of distinguish background and the electric vehicle lane by detecting the electric vehicle lane by using a multi-threshold set in advance with respect to the electric vehicle lane; a step of detecting a cross point, which is a contact point of the electric vehicle land and the pantograph; a step of converting units by substituting a proportional expression using the length of the pantograph into the cross point; and a step of obtaining displacement with a converted unit.
