We have developed a new system that continuously measures three-dimensional positions of the contact points of the pantograph and the trolley line of SHINKNSEN under running. Two CCD cameras are set up on the roof of the vehicle, and they acquire the images around the pantograph under high-speed running. By using image processing technique, our system extracts the pantograph and the trolley line from the images, and calculates three-dimensional positions of the contact points. This report describes system configuration of our system, the image processing procedures and some measurement results of the pantograph height and contact point deviation.
