Title:
摩耗測定装置及びその方法
Document Type and Number:
Japanese Patent JP5534058
Kind Code:
B1
Abstract:
A wear measuring device which has a wear measurement camera (2) to image the bottom face of the trolley wire (3) in contact with a pantograph (5) installed on the roof of a train (1) and comprises an image processing unit (10) that measures wear width of a trolley wire (3) by processing the image of the bottom of the trolley wire (3) that is imaged with the wear measurement camera (2), wherein two pantograph imaging cameras (6, 7) that image each marker (8, 9) mounted in two locations, on the left and right, of the pantograph (5) are installed on the roof of the train (1), an angle of inclination calculating unit (14) that calculates the angle of inclination of the entire pantograph (5) on the basis of images acquired by the pantograph imaging cameras (6, 7) is provided in the image processing unit (10), and a correction calculating unit (15) uses the angle of inclination of the entire pantograph (5) calculated by the angle of inclination calculating unit (14) as the angle of inclination of the trolley wire (3).
