| description | PROBLEM TO BE SOLVED: To measure the mounting angle of bendingly pulling metal fitting or the like supporting a trolley line in real time on an ultrahigh speed running measuring vehicle by using a laser beam source, receiving reflecting light from a trolley line supporting metal fitting to pick up the image, and computing mounting angle from the images of points over specific points. SOLUTION: Beams of light over three having fixed length in the running direction of a measuring vehicle 20 and at fixed intervals in the perpendicular direction to the running direction, laser beam sources 12a-12c generating over the measuring vehicle are provided. At timing when reflecting light from a trolley line supporting metal fitting such as a bendingly pulling metal fitting is obtained by a sensor, the image of a trolley line supporting metal fitting is picked up. By this, the trolley line supporting metal fitting can be caught as the images of points corresponding to the length of the beam of light. Then from the straight lines connecting together a plurality of points over three points, the angle of the trolley line supporting metal fitting can be easily computed. Hereby the mounting angle of the bendingly pulling metal fitting or the like can be measured in real time on an ultrahigh speed running measuring vehicle. |
