    摘要： Pantograph identification methods and devices including computer-implemented methods, software, computer systems for identifying a pantograph of an electric vehicle represented in an image captured by a camera. The method includes, for each pair of adjacent edges represented in the image, determining distances between the adjacent edges, wherein the distances are in a same direction for each of the distances. Then determining a point weight for points of the image associated with the distance by comparing the distance to a value or a value range representing a dimension of the pantograph. Further determining a region of the image that represents the pantograph based on the point weights.

    摘要： Computer-implemented methods, software, and computer systems for identifying a contact point between a pantograph of an electric vehicle and a power supply line represented in an image. The method includes, based on edges represented in the image, determining a first intersection point P1 and a second intersection point P2 that are sufficiently separated. The first intersection point P1 is formed by an intersection of a first edge Line with a top edge of the pantograph, and the second intersection point P2 is formed by an intersection of a second edge with the top edge of the pantograph. Then determining a first slope associated with the first edge, and a second slope associated with the second edge. Further, identifying the first intersection point P1 or the second intersection point P2 as the contact point between the pantograph and the power supply line by comparing the first slope and the second slope.

    摘要： A system for detecting arcing between two electrical conductors includes an image capture arrangement including a plurality of image capture devices configured to be arranged in spaced relationship relative to one another and to a contact region between the electrical conductors so as to provide depth information. A processor is responsive to the image capture arrangement for computing a depth range of the contact region between the electrical conductors relative to a first image capture device of the image capture arrangement and determining if an arcing candidate appears within the computed depth range for the first image capture device of the image capture arrangement and at least one further image capture device of the image capture arrangement and, if it does, flagging the candidate as arcing at the contact region.
