Since an image processing unit (5A) for determining the acceleration of a pantograph by processing the image of a marker captured by a line sensor camera (2) comprises a input image creating unit (5a) for creating an input image, a template setting unit (5b) for setting a template, an image diving unit (5c) for dividing the input image, a template enlarging/reducing unit (5d) for enlarging/reducing the template, a pattern matching unit (5e) for detecting the pixel position of the marker in the input image, a pantograph displacement calculating unit (5f) for converting the pixel position of the marker into the actual displacement of the pantograph, a filtering unit (5g) for smoothing the displacement of the pantograph, and an acceleration output unit (5h) for outputting the acceleration of the pantograph; the accuracy of the pattern matching is improved.
