In a device for measuring vertical acceleration of a pantograph by photographing an image of a pantograph by a line sensor camera (1) mounted on a vehicle body and calculating the vertical acceleration of the pantograph in an image processing portion (2) based on the image taken by the line sensor camera (1), the image processing portion (2) comprises an image input portion (21) for inputting an image of the pantograph photographed by the line sensor camera (1) at a measuring point of the pantograph, a pantograph position detecting portion (23) for detecting a position of the pantograph displayed by the line sensor camera (1) in accordance with an image process with respect to the input picture image, and a pantograph vertical acceleration measuring portion (24) for calculating vertical acceleration of the pantograph at a point for contacting the pantograph with a trolled wire based on one or more than transmitting functions previously obtained and a displacement of the pantograph, so that the vertical acceleration of the pantograph can be accurately measured by a compact device. |
