Abstract
Method for the video inspection of a pantograph (100) along an overhead contact line, including the steps of: detecting passage of the pantograph (100) in a plurality of monitoring stations (2); in each monitoring station (2), in response to the detection of the passage of the pantograph (100), illuminating a first overhead zone in which a portion of the pantograph (100) passes; in each monitoring station (2), during the step of illuminating the first overhead zone, acquiring images of the first overhead zone by way of at least one pair of stereo video cameras (5a, 5b); calculating the disparity between the images acquired; reconstructing a three-dimensional model of the portion of the pantograph (100).
