Abstract
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.
