摘要:
[Object] To ensure a wear measurement over an entire section of a trolley wire and to facilitate the wear measurement, and also to perform the measurement during daytime, without being affected by structures existing around the trolley wire. [Means to solve] A line sensor 5 and an illumination lamp 6, which are placed in a direction of a scanning line perpendicular to a laying direction of a trolley wire, are mounted on a test car 1. The line sensor 5 shoots a pantograph contact surface of the trolley wire by the running of the test car, and this image signal is saved in a recording device 8 through a measurement computer 7. The measurement computer 7 arranges luminance signals of scanning lines, obtained by the line sensor 5, in time series, and creates a line sensor image. The measurement computer 7 gets a binary operated line sensor image from this line sensor image. The measurement computer 7 further removes sky parts from this binary operated line sensor image and detects edges of a trolley wire worn portion, then determines a width of the trolley wire worn portion through an overall width of the trolley wire and a height, viewed from the line sensor, of the trolley wire.
摘要:
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).
摘要:
The present invention provides a trolley wire wear measurement device by image processing in which a line sensor is arranged vertically and upward on a roof of an inspection car so that the line sensor looks up to a trolley wire and a lighting means that illuminates the trolley wire is formed by arranging a plurality of point light sources in a straight line in a direction perpendicular to a travelling direction of the inspection car on the inspection car.
