IDENTIFICATION OF A CONTACT POINT BETWEEN A PANTOGRAPH AND A POWER SUPPLY LINE IN AN IMAGE

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.
