A crossover measuring device includes an illuminating member, a line sensor image forming section to form line sensor images respectively by lining up, in time series, luminance signals obtained by the crossover line sensor and the pantograph line sensor, and to store as input images; a discrimination analysis binarizing section to form a binary line sensor image in which the crossover part is emphasized by a discrimination analysis binarization of the line sensor image; a noise removing section to remove the noise of the binary line sensor image; a crossover part edge detecting section to detect edges of the crossover part in the binary line sensor image; a crossover part height calculating section to determine a width of the crossover part on the image, and to determine a height of the crossover; a crossover part deviation calculating section to determine a value of a center of the edges of the crossover, as a center of gravity of the crossover, and to determine a deviation of the center of the gravity from a center; a pantograph height and position calculating section to determine a height and a position of the pantograph; and a pantograph and crossover relative position calculating section to determine a relative position between the pantograph and the crossover. |
